Modem Management Commands

Modem Management Commands

This chapter describes the commands that manage modems existing inside access servers or routers. Cisco Systems does not consider external modems, which physically connect to an access server or router through an asynchronous cable, to be part of its modem management paradigm.

For configuration information and examples, refer to the "Managing Modems" chapter in the Dial Solutions Configuration Guide.

called-number

To assign a called party number to a pool of modems, use the called-number modem pool configuration command. Use the no form of this command to remove a number from a modem pool.

called-number number [max-conn number]
no called-number number [max-conn number]

Syntax Description

number

Called number for a modem pool.

max-conn number

(Optional) Maximum number of simultaneous connections allowed for the called party number.

Default

Disabled

Command Mode

Modem pool configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2 P.

A called party number is a telephone number that is used to reach a remote destination. For example, a mobile laptop dials a called party number to reach an ISP's POP. Some ISPs set up several called party numbers to enable remote clients to dial in, but to the end user, it appears and functions as one unified service.

Cisco's implementation of a called party number is based on the dialed number identification service (DNIS). You can configure multiple DNIS numbers in a single modem pool. However, the same DNIS number cannot be used in multiple modem pools. Each modem pool must be assigned different DNIS numbers.

Use the max-conn option to provide overflow protection, which specifies a maximum number of simultaneous connections that a called party number can consume. For example, if you create one modem pool to serve two or more services or customers, this option guarantees how many modems each service or customer can have access to at any given time.

The Cisco IOS software also includes a feature that simplifies the called number configuration. By using an x variable as the last digit in a called telephone number (for example, issuing the called-number 408555121x command), clients dialing different called numbers such as 4085551214 or 4085551215 will automatically be sent to the same modem pool. The x variable is a floating place holder for digits 1 through 9.


Note Modem pools using MICA or Microcom modems support incoming analog calls over ISDN  PRI. However, only MICA modems support modem pooling for CT1 and CE1 configurations with channel associated signaling.

Examples

In the following example, the modem pool called v90service is virtually partitioned between two customers using different DNIS numbers. The pool-range command assigns modems 1 to 110 to the shared modem pool. The called-number 5551212 max-conn 55 command assigns the DNIS number 5551212 to the v90service modem pool. The total number of simultaneous connections is limited to 55. The called-number 4441212 max-conn 55 command assigns the DNIS number 4441212, which is for a different customer, to the same v90service modem pool. The total number of simultaneous connections is also set to 55.

as5300# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
as5300(config)# modem-pool v90service
as5300(config-modem-pool)# pool-range 1-110
as5300(config-modem-pool)# called-number 5551212 max-conn 55
as5300(config-modem-pool)# called-number 4441212 max-conn 55
as5300(config-modem-pool)# exit
as5300(config)#

The following configuration rejects the pool-range 30 command because modem TTY line 30 is already a member of the modem pool v90service, which was configured in the previous example. Each modem in the access server is automatically assigned to a unique TTY line. TTY line numbers are assigned according to your shelf, slot, or port hardware configuration.

as5300(config)# modem-pool v34service
as5300(config-modem-pool)# pool-range 30
% TTY 30 is already in another pool.

clear modem

To reset the hardware for one or more manageable modems on an access server or router, use the clear modem EXEC command.

clear modem {slot/port-number | all | group group-number | at-mode slot/port-number |
group group-number}

Syntax Description

slot/port-number

Clear the modem at the specified slot and modem port number. Remember to include the forward slash (/) when entering this variable. For example: 1/1. This variable can also be used with the subcommands clear modem at-mode and clear modem counters.

all

Clear all modems. This command disconnects any active calls.

group group-number

Clears the modem hardware for a group of modems. The modem group-number is the number of the group you have previously created.

at-mode slot/port-number

Tears down an AT directly connected session. The variable, slot/port-number, is required. This EXEC command clears an attention (AT) directly connected session to a manageable Microcom modem from a second Telnet session.

Default

Disabled

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

The modem hardware is reset for modems that are idle or busied out for long periods of time.

An AT directly connected session is usually initiated and closed from the same Telnet session by using the modem at-mode command and Ctrl-C. However, you can clear an AT directly connected session that was mistakenly left open by enabling the clear modem at-mode command from a second Telnet session in to the access server.

Examples

The following example of the clear modem slot/port command resets the hardware for manageable modem 1/1:

as5300# clear modem 1/1

The following example of using the clear modem all command

as5300# clear modem all
This command will disconnect any active calls.
Clear (reset) all modems? [confirm]
Clearing modems................................................
Done
as5300#

The following examples of the clear modem group command clear the manageable modems in group 1:

clear modem group 1
clear modem group1

The following example executes the clear modem at-mode command from a Telnet session:

router# modem at-mode 1/1

The following example executes the clear modem at-mode command from a second Telnet session while the first Telnet session is connected to the modem:

router# clear modem at-mode 1/1
clear "modem at-mode" for modem 1/1 [confirm]
router#

The following output is displayed in the first Telnet session after the modem is cleared by the second Telnet session:

Direct connect session cleared by vty0 (171.69.1.164)

clear modem counters

To clear the statistical counters on one or more manageable modems installed in an access server, use the clear modem counters EXEC command.

clear modem counters [slot/port-number | group [group-number]]

Syntax Description

slot/port-number

Clear the modem at the specified slot and modem port number. Remember to include the forward slash (/) when entering this variable. For example: 1/1. This variable can also be used with the subcommands clear modem at-mode and clear modem counters.

group [group-number]

Clears the counter for one or all groups of modems. The subcommand, clear modem counters group, without the group-number clears counters in all modem groups. The optional modem group-number is the number of the group you have previously created. The Group number range is 1 through1002.

Default

Disabled

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

Entering the clear modem counters command without specifying an optional keyword or argument resets the modem statistics on each modem and the summary statistics displayed in the show modem summary command.

Examples

The following example of the clear modem counters slot/port command clears the statistical counters on manageable modem 1/1:

clear modem counters 1/1

The following example of the clear modem counters group command clears the statistical counters on all manageable modem groups:

copy modem

To copy modem firmware to integrated modems in an access server, use the copy modem EXEC command.

copy {flash | tftp | rcp} modem

Syntax Description

flash

Copies firmware from Flash memory to the modems.

tftp

Copies firmware from a local TFTP server on your network to the modems.

rcp

Copies firmware from a local rcp server on your network to the modems.

Default

Disabled

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2. For more information on this command, see the online configuration guides and command references for configuration fundamentals.

After you enable this command, you are asked to provide the download destination (a slot/port or all), the remote host name, and the path leading to the source modem firmware.

If a modem that you want to upgrade is busy with a call when the copy modem command is enabled, the upgrade for that modem yields until the active call is dropped. All other idle modems in the upgrade range proceed with the downloading operation.

Examples

The following example copies the modem firmware file called modem_upgrade from the TFTP server called Modem_Server to modem 2/0, which is installed in a Cisco AS5200 access server:

router# copy tftp modem
Modem Numbers (<slot>/<port>[-<slot>/<port>] | group <number> | all)? 2/0
Address or name of remote host [UNKNOWN]? Modem_Server
Source file name? dirt/elem/modem_upgrade
Accessing file 'dirt/elem/modem_upgrade on Modem_Server...
Loading dirt/elem/modem_upgrade .from 223.255.254.254 (via Ethernet0): ! [OK]

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

Example

The following example shows how to set the modem autotest to run once per week at 3:00 a.m. Additionally, the autotest will activate if the system detects a modem error count higher than 40  errors.

Step 1 Determine the current time set on the access server with the show clock EXEC command. In this example, the time and date set is 3:00 p.m, Monday, August 25, 1997:


Step 2 Enter global configuration mode and set the time you want the modem autotest to activate. In this example, the access server is configured to run the modem autotest each ongoing Tuesday at 3:00 a.m:

Step 3 Configure the autotest to activate if the system detects a high modem error count. In this example, the autotest activates if the system detects a modem error count higher than 40  errors. For the list of modem errors that are monitored by the modem autotest command, see the show modem call-stats command.

Step 4 Display the results of the modem autotest once the test has run through a test cycle by issuing the show modem test EXEC command:

Alternatively, you can view which modems were marked bad by the modem autotest by issuing the show modem EXEC command. Bad modems are marked by the letter B. In this example, modems 1/0 and 1/3 are marked bad (identified with a B), which takes them out of commission and unable to participate in dial services:

modem bad

To remove an integrated modem from service and indicate it as suspected or proven to be inoperable, use the modem bad line configuration command. Use the no form of this command to restore a modem to service.

modem bad

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

If you mark a modem as inoperable, it appears as Bad---without the asterisk (*)---in the Status column of the show modem command output. A modem marked inoperable by the modem startup-test command appears as Bad* in the show modem command output. Use the no modem bad command to unmark a modem as Bad* or Bad and restore it for dial-up connection services.


Note Only idle modems can be marked bad by the modem bad command. If you want to mark a modem bad that is actively supporting a call, first issued the modem shutdown command then issue the modem bad command.

Example

The first part of the following example shows a successful connection between modem 2/1 and modem 2/0, which verifies normal operating conditions between these two modems. However, when modem 2/1 is tested against modem 2/3, the back-to-back modem test fails. Therefore, modem 2/3 is suspected or proven to be inoperable. Modem 2/3 is removed from dial-up services through the use of the modem bad command on line 28.

disable

Mark the modem bad. Mark the originally faulty modem as bad and return all other modems back into service.

drop-call

Force firmware download by dropping holding calls. This forces the recovery by dropping any active calls remaining on modems within the module.

reschedule

Reschedule firmware download to next maintenance time. Leave the originally faulty modem as needing recovery and return all other modems back into service. Recovery will be attempted again on the following day. The default is set to reschedule.

max-download number

Maximum simultaneous recovery downloads. You must choose one number between 1 and 30. A range of values is not supported.

schedule

Scheduling method for modem recovery. Determines if the system should attempt module recovery as soon as a problem is found or wait for the maintenance window.

immediate

Immediately attempt module recovery.

pending

Delay recovery until maintenance time.

time hh:mm

Time of day for scheduled modem recovery. This is the actual time of day when the modem recovery maintenance process wakes up and starts recovering MICA modems. The default time is 3:00 AM.

window minutes

Amount of time for normal recovery to take place. This is the delay timer in minutes, which is between 0 and 360.

Default

The default action is set to reschedule. The default is modem recovery maintenance schedule is set to pending. The default time is 3:00 AM.

Command Mode

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 12.0.

MICA portware is downloaded on a modular basis and not on a modem basis. Thus, reloading MICA portware requires all 6 modems (or 12) in a module to be re-loaded.

Every 24 hours, the modem recovery maintenance process will wake up and attempt to recover any modems which are in the pending recovery state.

When a MICA module attempts to reload its portware, it must avoid taking down any modem connections that may exist. As such, the recovery process sets all modems currently not in use to recovery pending state. If any modems on the module are active, the recovery process waits for the calls to terminate normally. To avoid capacity problems from attempting recovery for an excessively long time period, a maintenance window is configured to require the modem recovery to take place within a specific timeframe. Otherwise, a given action is performed on that module when the window expires. The  default window is 60 minutes. This behavior is set using the modem recovery maintenance window minutes command.

When the modem recovery maintenance window expires, one of the following actions is performed on the modem module awaiting recovery: disable, reschedule, or drop-call. These options are associated with the modem recovery action command.

When the modem recovery maintenance process starts, it attempts to recover all modems in the recovery pending state. This can potentially be all modules on a given system. Thus, to avoid taking down all modems on a given system, only a maximum of simultaneous module recoveries can take place. The default is dynamically calculated to be 20% of the modules on a given system. This configuration allows that value to be overridden. These options are associated with the modem recovery maintenance max-download number command.

Example

The following example shows the available options for this command:

Router(config)# modem recovery maintenance ?
  action        Mode of recovery
  max-download  Maximum simultaneous recovery downloads
  schedule      Scheduling method for modem recovery
  time          Time of day for scheduled modem recovery

modem-pool

To create a new modem pool or to specify an existing modem pool, use the modem-pool global configuration command. Use the no form of this command to delete a modem pool from the access server's configuration.

modem-pool name
no modem-pool name

Syntax Description

name

Specifies the name of a modem pool.

Default

All modems are configured to be part of one system default modem pool (displayed as System-def-Mpool by the show modem-pool command.). For example, if you have 120 MICA modems loaded in your access server, then 120 modems are in the default modem pool.

Command Mode

Global configuration

Usage Guidelines

This command was first introduced in Cisco IOS Release 11.2 P.

Modem pools enable you to physically partition or virtually partition your access server for dial-in and dial-out access.

Physical partitioning is makes one access server appear as if it is multiple access servers loaded with different types of modem services (for example, v.34 modems, fax capable modems, and point-of-sale (POS) modems). Each service is part of one modem pool and assigned a unique DNIS number.

Virtual partitioning is creates one large modem pool on the access server, but enables different customers to dial-in and share the modem resources. Each customer is assigned its own DNIS number. Each customer is given overflow protection, which guarantees a certain number of simultaneous connections.


Note MICA and Microcom modems support incoming analog calls over ISDN  PRI. However, only MICA modems support modem pooling for CT1 and CE1 configurations with channel associated signaling.

Examples

The following example creates a modem pool called v90service. After the modem-pool v90service command is issued, modem pool configuration mode is accessed. The access server's prompt changes from as5300(config)# to as5300(config-modem-pool)#.

as5300# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
as5300(config)# modem-pool v90service
as5300(config-modem-pool)# 

The next example assigns modem TTY line numbers 30 to 50 to a modem pool. The DNIS number is set to 2000. The customers dialing the number 2000 are guaranteed access to 21 modems. The 22nd client to dial in is refused connectivity because the maximum number of allowable connections is exceeded.

as5300(config-modem-pool)# pool-range 30-50
as5300(config-modem-pool)# called-number 2000 max-conn 21
as5300(config-modem-pool)# exit
as5300(config)#

pool-range

To assign a range of modems to a modem pool, use the pool-range modem-pool configuration command.

pool-range number-number (Cisco AS5200 and Cisco AS5300)

Syntax Description

number-number

Assigns a range of TTY lines, which correspond to ranges of modems, to a modem pool. A dash (-) is required between the two modem numbers. The range of modems you can choose from is equivalent to the number of modems in your access server that are not currently associated with another modem pool.

Default

Disabled. All modems are configured to be part of the system default modem pool.

Command Mode

Modem pool configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2 P.

For a complete description of modem pools and how they are configured on Cisco access servers, see the command reference page for the modem-pool command.

Replace the number-number variable with the modem TTY line numbers that correspond with the range of modems you want in the modem pool. TTY line numbers start from 1, which map to modem numbers that start from 0. For example, if you want to include modems 1/0 through 1/23 in a pool range, use the TTY line numbers 1 to 24. To verify the modem to TTY line numbering scheme, enter the show modem slot/port command.


Note MICA and Microcom modems support incoming analog calls over ISDN  PRI. However, only MICA modems support modem pooling for CT1 and CE1 configurations with channel associated signaling.

Examples

The following example assigns modem TTY line numbers 30 to 50 to a modem pool. The DNIS number is set to 2000. The customers dialing 2000 are guaranteed access to 21 modems. The 22nd client to dial in is refused connectivity because the maximum number of allowable connections is exceeded.

as5300(config)# modem-pool v90service
as5300(config-modem-pool)# pool-range 30-50
as5300(config-modem-pool)# called-number 2000 max-conn 21
as5300(config-modem-pool)# exit
as5300(config)#

The following configuration rejects the pool-range 30 command, because modem TTY line 30 is already a member of the modem pool v90service, which was configured in the previous example. Each modem in the access server is automatically assigned to a unique TTY line. TTY line numbers are assigned according to your shelf, slot, or port hardware configuration.

as5300(config)# modem-pool v34service
as5300(config-modem-pool)# pool-range 30
% TTY 30 is already in another pool.
as5300(config-modem-pool)#

The type of display output generated from the show modem slot/port command depends on the version of Cisco IOS software running on the router or access server. For example, the following shows example output for a 56K modem card, which carries digital modems that transmit at 56 kbps. (In truth, 56K modems do not modulate or demodulate data. A pure digital-to-digital connection is made.) See Table 14 for a description of the fields displayed by this modem card.

RX signals

Transmit signal levels.

Last clearing of "show modem" counters

Last time the modem's counters were cleared using the clear modem counters command. A summary of modem events also appears.

  • Incoming completes and failures---Total number of incoming connection requests that the modem answered and successfully or unsuccessfully connected with the remote DCE.

  • Outgoing completes and failures---Total number of outgoing connection requests that the modem dialed and successfully or unsuccessfully connected with the remote DCE.

  • Failed dial attempts---Number of times the modem attempted to dial out but the call failed to leave the modem.

  • Ring no answers---Number of times the integrated modem detected ringing but did not answer the incoming call.

  • Busied outs---Number of times the integrated modem was intentionally taken out of service (for example, the modem busyout command was enabled on the modem).

  • No dial tones---Number of times the dial-out attempt failed because the modem failed to detect a dial tone.

  • Dial timeouts---Number of times the modem has timed out while attempting to dial.

  • Watchdog timeouts---Number of times the modem internal watchdog timer has expired.

  • No carriers---Number of times the modem disconnected because no carrier was present.

  • Link failures---Number of times the modem has detected a link failure.

  • Resets---Number of times the modem has been reset.

  • recover oob---Number of times the out-of-band feature has been cleared and re-initialized.

  • Lost events---Number of incomplete modem events performed by the modem.

Transmit Speed Counters:

List of connection speeds that were transmitted by the modem.

Receive Speed Counters:

List of connection speeds that were received by the modem.

Connection Speeds
# of connections

A complete summary of possible connection speeds and the actual number of connections that occurred at those speeds. Depending on which modem port module and version of software you are running, possible connection speeds range from 75 to 56,000 bps. The number of successful connections are displayed directly beneath the connection speed identifier. For example, the following output shows that three connections were made at 56 kbps.

Connection Speeds 56000
# of connections 3

The following example shows the sample display for modem group 1, which is composed of modem  1/0 through modem  1/23:

1/13, 1/14, 1/15, 1/16, 1/17, 1/18, 1/19, 1/20, 1/21, 1/22, 1/23

Related Commands

You can use the master indexes or search online to find documentation of related commands.

show mica module
show modem version

show modem at-mode

To display a list of the manageable Microcom modems that have open AT sessions and a list of users logged in to those sessions, use the show modem at-mode EXEC command.

show modem at-mode

Syntax Description

This command has no arguments or keywords.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

Sample Display

The following output shows that modem 1/1 has one open AT directly connected session:

router# show modem at-mode
Active AT-MODE management sessions:
Modem    User's Terminal
1/1 	0 cty 0

show modem call-stats

To display the local disconnect reasons for all modems inside an access server or router, use the show modem call-stats EXEC command.

show modem call-stats [slot]

Syntax Description

slot

(Optional) Specifies the slot number, which limits the display output to a particular range of modems in the system.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

Use this command to find out why a modem ended its connection or why a modem is not operating at peak performance.

Local disconnect reasons for a particular modem are listed across the top of the screen display. For example, see lostCarr, dtrDrop, rmtLink, wdogTimr, compress, retrain, inacTout, and linkFail in the following output:

router# show modem call-stats
  dial-in/dial-out call statistics
       lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail
  Mdm 
* 0/0 
* 0/1 

In the body of the screen display, the number of times an error occurred on a specific modem is displayed (see the # column). The % column shows the total running percent that a modem was logged for the specified disconnect reason with respect to the entire modem pool. For example, out of all the times the lostCarr error occurred on all the modems in the system, the lostCarr error occurred 2% of the time on modem 0/0.

router# show modem call-stats
  dial-in/dial-out call statistics
       lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail
  Mdm     #   %    #   %    #   %    #   %    #   %    #   %    #   %    #   %
* 0/0     6   2    2   3    1   0    0   0    0   0    0   0    0   0    0   0
* 0/1     5   2    2   3    2   1    0   0    0   0    0   0    0   0    0   0

Bad or malfunctioning modems are detected by an unusually high number of disconnect counters for a particular disconnect reason. For example, if modem 1/0 had an astronomically high number of compression errors compared to the remaining modems in system, modem 1/0 would probably be bad or inoperable.

To reset the counters displayed by the show modem call-stats command, issue the clear modem counters command.


Note Remote disconnect reasons are not described by this command.

Sample Display

The following example shows call statistics for the show modem call-stats command. Due to the screen size limitation of most terminal screen displays, all the possible disconnect reasons cannot be displayed at the same time. Only the top eight most frequently experienced disconnect reasons are displayed.

Table 15 describes the show modem call-stats fields.


Table 15: Show Modem Call-Stats Field Descriptions
Field Description

dial-in/dial-out call statistics

This category of disconnect reasons can happen only in dial-in or dial-out scenarios.

wdogTimr

Watchdog timeout. An obscure firmware problem occurred. This is a rare disconnect reason.

compress

Compression. An error was detected during decompression, which caused the internal decompression dictionary to overflow. This could be caused by a modem dialing in that is using a slightly different compression algorithm.

retrain

Retrain failure. A connection was lost and not re-established after three attempts.

inacTout

Inactivity timeout. The time specified in the AT/T command has expired. No modem data transfers were detected during that period.

linkFail

Link failure. The protocol level link failed while using MNP-10 or LAPM in reliable mode.

moduFail

Modulation error. An error was detected at the DSP chip level, which caused a disconnect.

mnpProto

MNP10 protocol error. An uncorrectable error occurred during a MNP-10 connection.

lapmProt

LAPM protocol error. An uncorrectable error occurred during a LAPM connection.

lostCarr

Lost carrier. The modem firmware detected a carrier drop during a connection. The cause for the carrier drop could be the loss of signal from the remote modem or the result of a error detection.

dtrDrop

DTR drop. The modem disconnected because the DTR signal from the host became inactive.

userHgup

User hang up. The modem disconnected because a command such as ATH was detected.

rmtlink

Remote link disconnect. If an MNP-10 reliable link is established, the remote modem sends the disconnect reason across the link before disconnecting. The disconnect reason displayed is LOCAL (remote link disconnect) and REMOTE (the reason the remote modem disconnected).

trminate

Terminate. A password security error occurred in the Microcom HDMS. This error occurs only with Microcom modems.

callBkfa

Callback failed. This error applies to leased line connections only. A switched line connection failed and a connection still cannot be made on the leased line.

dial-out call statistics

This category of disconnect reasons can happen only in a dial-out scenario.

noCarr

No carrier. The called number answered, but no answer tone was detected after the appropriate wait.

noDitone

No dialtone. No dial tone was detected after the modem went off hook.

busy

Busy. A busy signal was detected while the local modem was attempting to dial.

abort

Abort. A character was received from the remote host after the dial command was issued and before a connection was established.

dialStrg

Dialstring error. An invalid character was detected in the dial string, which forced the dial attempt to terminate.

autoLgon

Autologon error. An autologon sequence did not successfully complete.

dialTout

Dial timeout. When a semicolon is used as a dial modifier, the modem returns to the command state as indicated by an "OK." This allows a continuation of the dial string. If a period of time elapses as specified in the S7 register without the dial string completing, the attempt is aborted with dial timeout as the disconnect reason.

rmtHgup

Remote hang-up. The modem disconnected because the remote modem disconnected the call and dropped DTR.

blacklst

Blacklist. In a country that supports blacklisting, an attempt was made to go off hook with a null dial string (ATD).

ccpNssn

CCP not seen. The credit card prompt (also known as Bong) was not detected.

faxClasz

FAX class 2 error. An abnormal termination to a fax transmission was detected.

Total

Total number of times the disconnect reason occurred among all the modems in the system.

show modem configuration

To display the current modem configuration for digital MICA modems loaded inside an access server or router, use the show  modem configuration EXEC command.

show modem configuration [slot/port]

Syntax Description

slot/port

(Optional) Specifies the location of a slot and modem port. If this number is not specified, statistics for all connected modems are displayed. Remember to include the forward slash (/) when entering this variable.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2 P.

show modem operational-status
show modem mica
show modem log

show modem connect-speeds

To display connection speed statistics for all the modems running in an access server or router, use the show modem connect-speeds EXEC command.

show modem connect-speeds [max-speed [slot]]

Syntax Description

max-speed

(Optional) Maximum speed you want displayed in the shifting speed window. You can specify from 12,000 to 56,000 bps.

slot

(Optional) Specifies the slot number, which limits the display output to a particular range of modems in the system.

Default

The maximum speed displayed is 12,000 bps.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

Because most terminal screens are not wide enough to display the entire range of connection speeds at one time (for example, 75 to 56000 bps), the max-speed variable is used. This variable specifies the contents of a shifting baud-rate window, which provides you with a snap shot of modem connection speeds for your system. If you want to see a snap shot of lower baud rates, specify a lower connection speed. If you want to see a snap shot of higher baud rates, specify a higher connection speed.

The max-speed variable also rounds up to the nearest recognizable baud rate by the software, so you do no need to memorize or enter exact connection speeds. For example, if you enter a maximum baud rate of 22059, the system software automatically rounds the value up to 24000.

To display a complete picture of all the connection speeds and counters on the system, you must enter a series of commands. Each time you issue the show modem connect-speeds max-speed command, only nine baud rate columns can be displayed at the same time.

Table 17 shows a range of commands that you can issue, one at a time, to see a complete picture of the total possible connection speeds on your access server.


Table 17: Connect Speed Displays for the Show Modem Connect-Speeds Command
Command Connect Speed Range Displayed

show modem connect-speeds 56000

40,000 to 56,000 bps

show modem connect-speeds 38000

24,000 to 38,000 bps

show modem connect-speeds 21600

2,400 to 21,600 bps

show modem connect-speeds 12000

75 to 1200 bps

The show modem connect-speeds command displays a log of connection speed statistics starting from the last time the access servers or router was power cycled or the clear modem counters command was issued. If you want to create a monthly report of the connection speeds achieved by the modems, issue the clear modem counters command at the beginning of the month and issue the show modem connect-speeds command at the end of the month.


Note The Cisco IOS software does not accept commas (,) in the connect speed field. For example, enter 28000 not 28,000.

show modem mapping

To display a snapshot of all the firmware versions running on all the modems in the access server, use the show modem mapping EXEC command. This command also shows the source location of each version of firmware (for example, running out of Flash, boot Flash, or bundled with Cisco IOS software).

show modem mapping

Syntax Description

This command has no additional keywords or arguments.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3 T.

This command is useful for managing and monitoring multiple versions of modem firmware running in an access server.

Modem firmware can reside in the access server's Flash, boot Flash, or bundled with the Cisco IOS software.

Firmware can also be copied from a local TFTP server to the onboard modems. For the Cisco  AS5300, issue the copy tftp flash command followed by the copy flash modem command. The Cisco AS5300 stores individual firmware files that are not bundled with the Cisco IOS software in Flash memory. For the Cisco AS5200, issue the copy tftp bootflash command followed by the copy bootflash modem command. The Cisco AS5200 stores individual firmware files not bundled with the Cisco IOS software in boot Flash memory.

All the modems in a single MICA modem module run the same version of firmware (for example, modems 1/0 through 1/5 in module 0). However, different versions of modem firmware can exist between different modem modules (for example, module 0 and module 1).

Individual firmware files cannot be erased from Flash or boot Flash memory. The entire contents of Flash or boot Flash memory must be deleted during the erase operation. If you do this, be sure to backup your Cisco IOS software and running configuration before you erase your system's Flash or boot Flash memory.

Sample Display

The following is sample display output for the show modem mapping EXEC command. This access server is loaded with MICA and Microcom modems. Table 24 describes each field in the display.

Syntax Description

slot/port

Specifies the display for a single modem in a MICA digital modem board.

all

Displays output for all the MICA modems in the system.

slot number

Displays output for a particular slot, which is mainly used for debugging purposes. The optional number variable allows you to specify a slot number.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2 P.

Each MICA modem has its own data channel port, which is tied to its own TTY line. For example, modem 0/1 is tied to TTY line 2. To display data channel information for a single MICA modem, issue the show modem mica slot/port command.

All the modems on each MICA modem card share three pseudo channels for modem management functions, for example the DC session channel, status polling channel, and controlling channel. To view statistics for each modem management channel, issue the show modem mica all command. The first channel you see displayed is the status polling channel (shown as SLOT/PORT (0/61) TTYNUM=-1 (MM Status Port)). The second displayed channel is the DC session channel (shown as SLOT/PORT (0/60) TTYNUM=-1 (MM DC Port)). The third displayed port is the controlling channel (shown as SLOT/PORT (0/62) TTYNUM=-1 (Control Port)). No TTY lines are associated with the modem management ports, as indicated by the field display TTYNUM=-1. Finally, an extensive list of all the data channels for each MICA modem is displayed.

show modem-pool

To display the configuration and connection status for one or more modem pools, use the show modem-pool EXEC command.

show modem-pool [name]

Syntax Description

name

(Optional) Modem pool name.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2 P.

The counters display by the show modem-pool command are cleared with the clear counters (async) command.

Sample Display

In the following example, two modem pools are set up: v90service and v34service. Each pool contains one DNIS number: 1234 and 5678. Each DNIS number is allowed a maximum of 48 simultaneous connections. A total of 96 modems are assigned to the modem pools: 48 and 48. Modems that are left unassigned to modem pools are automatically put into the default modem pool (displayed as System-def-Mpool). The default pool is empty in this example.

as5300# show modem-pool
modem-pool: System-def-Mpool
modems in pool: 0     active conn: 0
0 no free modems in pool
modem-pool: v90service
modems in pool: 48    active conn: 46
 8 no free modems in pool
 called_party_number: 1234
   max conn allowed: 48, active conn: 46
   8 max-conn exceeded, 8 no free modems in pool
modem-pool: v34service
modems in pool: 48    active conn: 35
 0 no free modems in pool
 called_party_number: 5678
   max conn allowed: 48, active conn: 35
   0 max-conn exceeded, 0 no free modems in pool

Table 30 describes the modem-pool fields.


Table 30: Show Modem-Pool Field Descriptions
Field Description

modem-pool

Name of the modem pool. In the previous example, there are three modem pools configured: System-def-Mpool, v34service, and v90service. To set modem pool name, see the clear counters (async) command.

All the modems not assigned to a modem pool are automatically assigned to the system default pool (displayed as System-def-Mpool).

modems in pool

Number of modems assigned to the modem pool. To assign modems to a pool, see the clear counters (async) command.

active conn

Number of simultaneous active connections for the specified modem pool or called party DNIS number.

no free modems in pool

Number of times incoming calls were rejected because there were no more free modems in the pool to accept the call.

called_party_number

Specified called party DNIS number. This is the number that the remote clients use to dial into the access server. You can have more than one DNIS number per modem pool. To set the DNIS number, see the called-number command.

max conn allowed

Maximum number of modems that a called party DNIS number can use, which is an overflow protection measure. To set this feature, see the called-number command.

max-conn exceeded

Number of times an incoming call using this called party DNIS number was rejected because the max-conn number parameter specified by the called-number command was exceeded.

test modem back-to-back

To diagnose an integrated modem that may not be functioning properly, use the test modem back-to-back EXEC command.

test modem back-to-back first-slot/port second-slot/port

Syntax Description

first-slot/port

Slot and modem number of the first test modem. Remember to include the forward slash (/) when entering this variable.

second-slot/port

Slot and modem number of the second test modem. Remember to include the forward slash (/) when entering this variable.

Default

Disabled

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

Use this command to perform back-to-back testing of two modems. You might need to enable this command on several different combinations of modems to determine which one is not functioning properly.

Example

The following example performs a back-to-back modem test between modem 2/0 and modem 2/1 and removes modem 2/1 (which is associated with TTY line 26) from all dial-in and dial-out services:

router# test modem back-to-back 2/0 2/1
back2back 2/0 2/1
Repetitions (of 10-byte packets) [1]: 
router#
%MODEM-5-B2BCONNECT: Modems (2/0) and (2/1) connected in back-to-back test: 
CONNECT9600/REL-MNPM
%MODEM-5-B2BMODEMS: Modems (2/0) and (2/1) completed back-to-back test: success/packets 
= 2/2
