show aps

To display information about the current automatic protection switching (APS) feature, use the show  aps EXEC command.

show aps

Syntax Description

This command has no arguments or keywords.

Command Mode

Privileged EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.1 CC.

Sample Displays

The following is sample output of the show aps command on a router configured with a working interface. In this example, POS interface 0/0/0 is configured as a working interface in group 1, and the interface is selected (that is, active).

router1# show aps
POS0/0/0 working group 1 channel 1 Enabled Selected

The following is sample output of the show aps command on a router configured with a protect interface. In this example, POS interface 2/0/0 is configured as a protect interface in group 1, and the interface is not selected (the ~ indicates that the interface is not active). The output also shows that the working channel is located on the router with the IP address 15.1.6.1 and that the interface is currently selected (that is, active).

router2# show aps
POS2/0/0 protect group 1 channel 0 bidirectional ~Selected
        Rx_K1= 0, Rx_K2= 0 Tx_K1= 0 Tx_K2= 5
        Working channel 1 at 15.1.6.1 Enabled 

For the K1 field (8 bits), the first 4 bits indicate the channel number that has made the request, and the last 4 bits map to the requests (local or external) listed in Table 12. For the K2 field (8 bits), the first 4 bits indicate the channel number bridged onto the protect line, the next bit is the architecture used, and the last 3 bits indicate the mode of operation or non-APS use listed in Table 13.

Table 20: Show Controllers MCI Field Descriptions
Field Description

MCI 0

Card type and unit number (varies depending on card).

controller type 1.1

Version number of the card.

microcode version 1.8

Version number of the card's internal software (in read-only memory).

128 Kbytes of main memory

Amount of main memory on the card.

4 Kbytes cache memory

Amount of cache memory on the card.

22 system TX buffers

Number of buffers that hold packets to be transmitted.

largest buffer size 1520

Largest size of these buffers (in bytes).

Restarts
     0 line down
     0 hung output
     0 controller error

Count of restarts due to the following conditions:
     Communication line down
     Output unable to transmit
     Internal error

Interface 0 is Ethernet0

Names of interfaces, by number.

electrical interface is V.35 DTE

Line interface type for serial connections.

15 total RX buffers

Number of buffers for received packets.

11 buffer TX queue limit

Maximum number of buffers in transmit queue.

Transmitter delay is 0 microseconds

Delay between outgoing frames.

Station address 0000.0c00.d4a6

Hardware address of the interface.


Note The interface type is only queried at startup. If the hardware changes subsequent to initial startup, then the wrong type is reported. This has no adverse effect on the operation of the software. For instance, if a DCE cable is connected to a dual-mode V.35 applique after the unit has been booted, then the display presented for show interfaces incorrectly reports attachment to a DTE device although the software recognizes the DCE interface and behaves accordingly.

Table 21: Show Controllers POS Field Descriptions
Field Description

POS2/0/0

Slot number of the POS interface.

LOF

Section loss of frame is detected when a severely error framing (SEF) defect on the incoming SONET signal persist for 3 milliseconds.

LOS

Section loss of signal is detected when an all-zeros pattern on the incoming SONET signal lasts 19 (+-3) microseconds or longer. This defect might also be reported if the received signal level drops below the specified threshold.

BIP(B1)/BIP(B2)/BIP(B3)

Bit interleaved parity error reported.

For B1, the bit interleaved parity error report is calculated by comparing the BIP-8 code with the BIP-8 code extracted from the B1 byte of the following frame. Differences indicate that section level bit errors have occurred.

For B2, the bit interleaved parity error report is calculated by comparing the BIP-8/24 code with the BIP-8 code extracted from the B2 byte of the following frame. Differences indicate that line level bit errors have occurred.

For B3, the bit interleaved parity error report is calculated by comparing the BIP-8 code with the BIP-8 code extracted from the B3 byte of the following frame. Differences indicate that path level bit errors have occurred.

AIS

Alarm indication signal.

Line alarm indication signal is sent by the section terminating equipment (STE) to alert the downstream line terminating equipment (LTE) that a LOS or LOF defect has been detected on the incoming SONET section.

Path alarm indication signal is sent by the LTE to alert the downstream path terminating equipment (PTE) that it has detected a defect on its incoming line signal.

RDI

Remote defect indication.

Line remote defect indication is reported by the downstream LTE when it detects LOF, LOS, or AIS.

Path remote defect indication is reported by the downstream PTE when it detects a defect on the incoming signal.

FEBE

Far end block errors.

Line far end block error (accumulated from the M0 or M1 byte) is reported when the downstream LTE detects BIP(B2) errors.

Path far end block error (accumulated from the G1 byte) is reported when the downstream PTE detects BIP(B3) errors.

LOP

Path loss of pointer is reported as a result of an invalid pointer (H1, H2) or an excess number of new data flag (NDF) enabled indications.

NEWPTR

An inexact count of the number of times the SONET framer has validated a new SONET pointer value (H1, H2).

PSE

An inexact count of the number of times the SONET framer has detected a positive stuff event in the received pointer (H1, H2).

NSE

An inexact count of the number of times the SONET framer has detected a negative stuff event in the received pointer (H1, H2).

Active Defects

List of all currently active SONET defects.

Active Alarms

List of current Alarms as enforced by Sonet Alarm Hierarchy.

Alarm reporting enabled for

List of alarms that you enabled reporting for with the pos report interface command.

APS

Automatic protection switching.

COAPS

An inexact count of the number of times a new APS value has been detected in the K1, K2 bytes.

PSBF

An inexact count of the number of times a protection switching byte failure has been detected (no three consecutive SONET frames contain identical K1 bytes).

PSBF_state

Protection switching byte failure state.

Rx(K1/K2)/Tx(K1/K2)

Contents of the received and transmitted K1 and K2 bytes. For more information on the K1 field, refer to Table 12. For more information on the K2 field, refer to Table 13.

S1S0

The two S bits received in the last H1 byte.

C2

The value extracted from the SONET path signal label byte (C2).

CLOCK RECOVERY

SONET clock is recovered using information in the SONET overhead. RDOOL is an inexact count of the number of times Receive Data Out Of Lock has been detected which indicates the clock recovery phased lock loop is unable to lock to the receive stream.

PATH TRACE BUFFER

SONET path trace buffer is used to communicate information regarding the remote hostname, interface name/number and IP address. This is a Cisco-proprietary use of the J1 (path trace) byte.

BER thresholds

List of the bit error rate (BER) thresholds you configured with the pos threshold interface command.

TCA thresholds

List of threshold crossing alarms (TCA) you configured with the pos threshold interface command.

show controllers serial

Use the show controllers serial privileged EXEC command to display information that is specific to the interface hardware.

show controllers serial [slot/port]

Table 22: Show Controller T1 Field Descriptions
Field Description

T1 0/0 is up.

The T1 controller 0 in slot 0 is operating. The controller's state can be up, down, administratively down. Loopback conditions are shown by (Locally Looped) or (Remotely Looped).

No alarms detected.

Any alarms detected by the controller are displayed here. Possible alarms are as follows:

Transmitter is sending remote alarm.

Transmitter is sending AIS.

Receiver has loss of signal.

Receiver is getting AIS.

Receiver has loss of frame.

Receiver has remote alarm.

Receiver has no alarms.

Data in current interval (725 seconds elapsed)

Shows the current accumulation period, which rolls into the 24-hour accumulation every 15 minutes. Accumulation period is from 1 to 900  seconds. The oldest 15 minute period falls off the back of the 24-hour accumulation buffer.

Line Code Violations

Indicates the occurrence of either a Bipolar Violation (BPV) or Excessive Zeros (EXZ) error event.

Path Code Violations

Indicates a frame synchronization bit error in the D4 and E1-noCRC formats, or a CRC error in the ESF and E1-CRC formats.

Slip Secs

Indicates the replication or deletion of the payload bits of a DS1 frame. A slip may be performed when there is a difference between the timing of a synchronous receiving terminal and the received signal.

Fr Loss Secs

Indicates the number of seconds an Out Of Frame (OOF) error is detected.

Line Err Secs

Line Errored Seconds (LES) is a second in which one or more Line Code Violation errors are detected.

Degraded Mins

A Degraded Minute is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3.

Errored Secs

In ESF and E1-CRC links, an Errored Second is a second in which one of the following are detected: one or more Path Code Violations; one or more Out of Frame defects; one or more Controlled Slip events; a detected AIS defect.

For D4 and E1-noCRC links, the presence of Bipolar Violations also triggers an Errored Second.

Bursty Err Secs

A second with fewer than 320 and more than 1 Path Coding Violation error, no Severely Errored Frame defects and no detected incoming AIS defects. Controlled slips are not included in this parameter.

Severely Err Secs

For ESF signals, a second with one of the following errors: 320 or more Path Code Violation errors; one or more Out of Frame defects; a detected AIS defect.

For E1-CRC signals, a second with one of the following errors: 832 or more Path Code Violation errors; one or more Out of Frame defects.

For E1-noCRC signals, a second with 2048 Line Code Violations or more.

For D4 signals, a count of 1-second intervals with Framing Errors, or an Out of Frame defect, or 1544 Line Code Violations.

Unavail Secs

A count of the total number of seconds on the interface.

show controllers t3

To display information about the Channelized T3 Interface Processor (CT3IP) on Cisco  7500 series routers, use the show controllers  t3 privileged EXEC command.

show controllers t3 [slot/port-adapter/port [:t1-channel]] [brief | tabular | remote performance [brief | tabular]]

:t1-channel

(Optional) For the CT3IP, the T1 channel is a number between 1 and 28.

remote performance

(Optional) Displays the far-end ANSI performance monitor information when enabled on the T1 channel with the t1 fdl ansi controller command.

brief

(Optional) Displays a subset of information.

tabular

(Optional) Displays information in a tabular format.

Command Mode

Privileged EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

This command was modified in Cisco IOS Release 11.3 to include the remote performance keyword.

This command displays controller status that is specific to the controller hardware. The information displayed is generally useful for diagnostic tasks performed by technical support personnel only.


Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This is to ensure consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

The show controllers t3 command also displays Maintenance Data Link (MDL) information (received strings) if MDL is configured and framing is set to C-bit.

  • Transmitter is sending AIS.

  • Receiver has loss of signal.

  • Receiver is getting AIS.

  • Receiver has loss of frame.

  • Receiver has remote alarm.

  • Receiver has no alarms.

MDL transmission is disabled

Status of the maintenance data link (either enabled or disabled).

FEAC code received

Whether or not a far-end alarm code request is being received. Possible values are as follows:

  • DS3 Eqpt. Failure (SA)

  • DS3 LOS/HBER

  • DS3 Out-of-Frame

  • DS3 AIS Received

  • DS3 IDLE Received

  • DS3 Eqpt. Failure (NSA)

  • Common Eqpt. Failure (NSA)

  • No code is being received

Framing is M23

Framing type on the CT3IP. Values are: M23, C-Bit, and Auto-detect.

Line Code is B3ZS

Line coding format on the CT3IP.

Clock Source is Internal

Clock source on the CT3IP. Values are: internal or line.

BERT test result

BERT test information is available if the t1 bert controller command is enabled for the T1 channel on the CT3IP. The BERT results include the following information:

  • Test Pattern---Type of test pattern selected.

  • Status---Status of the test.

  • Sync Detected---Number of times the pattern synch is detected (that is, the number of times the pattern goes from No Sync to Sync).

  • Interval---Duration selected.

  • Time Remain---Time remaining on the BERT test.

  • Bit Errors(Sync BERT Started)---Number of bit errors during the BERT test.

  • Bit Errors(Sync last Sync)---Number of bit errors since the last patter sync was detected.

  • Bits Received---Total bits received.

When the T1 channel has a BERT test running, the line state is DOWN. Also, when the BERT test is running and the Status field is Not Sync, the information in the total bit errors field is not valid. When the BERT test is done, the Status field is not relevant.

Data in current interval (39  seconds elapsed)

Shows the current accumulation period, which rolls into the 24-hour accumulation every 15 minutes. Accumulation period is from 1 to 900  seconds. The oldest 15-minute period falls off the back of the 24-hour accumulation buffer.

Line Code Violations

Line Code Violations (LCV) is a count of both Bipolar Violations (BPVs) and Excessive Zeros (EXZs) occurring over the accumulation period. An EXZ increments the LCV by one regardless of the length of the zero string.

P-bit Coding Violation

For all DS3 applications, a P-bit coding violation (PVC) error event is a P-bit parity error event. A P-bit parity error event is the occurrence of a received P-bit code on the DS3 M-frame that is not identical to the corresponding locally calculated code.

C-bit Coding Violation

For C-bit parity and SYNTRAN DS3 applications, the C-bit coding violation (CCV) is the count of coding violations reported via the C-bits. For C-bit parity, it is the count of CP-bit parity errors occurring in the accumulation interval. For SYNTRAN, it is a count of CRC-9 errors occurring in the accumulation interval.

P-bit Err Secs

P-bit errored seconds (PES) is a second with one or more PCVs, one or more out of frame defects, or a detected incoming AIS. This gauge is not incremented when unavailable seconds are counted.

P-bit Severely Err Secs

P-bit severely errored seconds (PSES) is a second with 44 or more PCVs, one or more out of frame defects, or a detected incoming AIS. This gauge is not incremented when unavailable seconds are counted.

Severely Err Framing Secs

Severely errored framing seconds (SEFS) is a second with one or more out of frame defects or a detected incoming AIS.

Unavailable Secs

Unavailable seconds (UAS) are calculated by counting the number of seconds that the interface is unavailable. For more information, refer to RFC 1407.

Line Err Secs

Line errored seconds (LES) is a second in which one or more code violations occurred or one or more LOS defects.

C-bit Errored Secs

C-bit errored seconds (CES) is a second with one or more C-bit code violations (CCV), one or more Out of Frame defects, or a detected incoming AIS. This gauge is not incremented when UASs are counted.

C-bit Severely Errored Secs

C-bit severely errored seconds (CSES) is a second with 44 or more CCVs, one or more Out of Frame defects, or a detected incoming AIS. This gauge is not incremented when UASs are counted.

Total Data (last 1 15 minute intervals)

Shows the last 15-minute accumulation period.

T1 1 is up

T1 channel is operating. The channel's state can be up, down, administratively down. Loopback conditions are shown by (Locally looped) or (Remotely looped).

speed

Speed of the T1 channel in kbps.

non-inverted data

Indicates if the T1 channel is configured for inverted data.

timeslots

Timeslots assigned to the T1 channel.

FDL per AT&T 54016 spec.

Performance monitoring is via Facility Data Link per ANSI T1.403.

No alarms detected

Any alarms detected by the T1 controller are displayed here. Possible alarms are as follows:

  • Transmitter is sending remote alarm.

  • Transmitter is sending AIS.

  • Receiver has loss of signal.

  • Receiver is getting AIS.

  • Receiver has loss of frame.

  • Receiver has remote alarm.

  • Receiver has no alarms.

Framing is ESF

Type of framing used on the T1 channel. Values are: ESF or SF.

LineCode is B8ZS

Type of line coding used on the T1 channel. Values are: B8ZS or AMI.

Clock Source is Internal

Clock source on the T1 channel. Values are: internal or line.

Path Code Violations

Path coding violation (PCV) error event is a frame synchronization bit error in the D4 and E1-noCRC formats or a CRC error in the ESF and E1-CRC formats.

Slip Secs

Controlled slip second (CSS) is a one-second interval containing one or more controlled slips.

Fr Loss Secs

Frame loss seconds (SELS) is the number of seconds an Out Of Frame (OOF) error is detected.

Line Err Secs

Line errored seconds (LES) is a second in which one or more line code violation errors are detected.

Degraded Mins

Degraded minute (DM) is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3. For more information, refer to RFC 1406.

Errored Secs

Errored seconds (ES) is a second with one or more path coding violations, one or more Out of Frame defects, or one or more controlled slip events or a detected AIS defect.

Bursty Err Secs

Bursty errored seconds (BES) is a second with fewer than 320 and more than one path coding violation error events, no Severely Errored Frame defects, and no detected incoming AIS defects. Controlled slips are not included in this parameter.

Severely Err Secs

Severely errored seconds (SES) is a second with 320 or more path code violation errors events, one or more Out of Frame defects, or a detected AIS defect.

Stuffed Secs

Stuffed seconds (SS) is a second in which one more bit stuffings take place. This happens when the Pulse Density Enforcer detects a potential violation in the output stream and inserts a 1 to prevent it. Such bit stuffings corrupt user data and indicate the network is misconfigured. This counter can be used to help diagnose this situation.

show controllers token

To display information about memory management and error counters on the Token Ring Interface Processor (TRIP) for the Cisco 7500 series, use the show controllers token privileged EXEC command.

show controllers token

Syntax Description

This command has no arguments or keywords.

Command Mode

Privileged EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 10.0.

The information was modified in Cisco IOS Release 11.3(3)T to include the PA-4R-FDX full-duplex Token Ring port adapter.

Depending on the card being used, the output can vary. This command also displays information that is proprietary to Cisco Systems. Thus, the information that show controllers token displays is of primary use to Cisco technical personnel. Information that is useful to users can be obtained with the show interfaces tokenring command, which is described later in this chapter.

show hub

To display information about the hub (repeater) on an Ethernet interface of a Cisco 2505 or Cisco  2507, use the show hub EXEC command.

show hub [ethernet number [port [end-port]]]

ethernet

(Optional) Indicates that this is an Ethernet hub.

number

(Optional) Hub number, starting with 0. Since there is currently only one hub, this number is 0.

port

(Optional) Port number on the hub. On the Cisco 2505, port numbers range from 1 through 8. On the Cisco 2507, port numbers range from 1 through 16. If a second port number follows, then this port number indicates the beginning of a port range.

end-port

(Optional) Ending port number of a range.

Syntax Description

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 10.3.

If you do not specify a port or port range for the show hub command, the command displays all ports (for example, ports 1 through 16 on a Cisco 2507) by default. Therefore, the commands show hub, show hub ethernet 0, and show  hub ethernet 0 1 16 all produce the same result.

If no ports are specified, the command displays some additional data about the internal port. The internal port is the hub's connection to Ethernet interface 0 inside the box. Ethernet interface 0 still exists; physical access to the interface is via the hub.

Sample Displays

The following is sample output from the show hub command for hub 0, port 2 only:

Table 25 describes significant fields shown in the display.


Table 25: Show Hub Field Descriptions
Field Description

Port ... of ... is administratively down

Port number out of total ports; indicates whether the interface hardware is currently active, or down due to the following:

  • The link-state test failed.

  • The MAC address mismatched when source address configured.

  • It has been taken down by an administrator.

link state is up

Indicates whether port has been disabled by the link-test function. If the link-test function is disabled by the user, nothing will be shown here.

packets input

Total number of error-free packets received by the system.

bytes

Total number of bytes, including data and MAC encapsulation, in the error free packets received by the system.

errors

Sum of FCS, alignment, too long, short, runts, very long, and rate mismatches.

collisions

Number of messages retransmitted due to Ethernet collisions.

FCS

Counter for the number of frames detected on the port with an invalid frame check sequence.

alignment

Counter for the number of frames of valid length (64 bytes to 1518 bytes) that have been detected on the port with an FCS error and a framing error.

too long

Counter for the number of frames that exceed the maximum valid packet length of 1518 bytes.

short

Counter for the number of instances when activity is detected with duration less than 74-82 bit times.

runts

Number of packets that are discarded because they are smaller than the medium's minimum packet size. For example, any Ethernet packet that is less than 64 bytes is considered a runt.

late

Counter for the number of instances when a collision is detected after 480-565 bit times in the frame.

very long

Counter for the number of times the transmitter is active in excess of 4 ms to 7.5 ms.

rate mismatches

Counter for the number of occurrences when the frequency, or data rate of incoming signal is noticably different from the local transmit frequency.

auto partitions

Counter for the number of instances where the repeater has partitioned the port from the network.

last source address

Source address of last packet received by this port. Indicates "none" if no packets have been received since power on or a hub reset.

Last clearing of "show hub" counters

Elapsed time since clear hub counters command. Indicates "never" if counters have never been cleared.

Repeater information (Connected to Ethernet0)

Indicates that the following information is about the hub connected to the Ethernet interface shown.

... bytes seen with ... collisions, ... hub resets

Hub resets is the number of times the hub has been reset by network management software or by the clear hub command.

Version/device ID 0/1 (0/1)

Hub hardware version. IMR+ version device of daughter board.

Internal Port (Connected to Ethernet0)

Set of counters for the internal AUI port connected to the Ethernet interface.
