show atm vc

To display all ATM virtual circuits (PVCs and SVCs) and traffic information, use the show  atm  vc privileged EXEC command.

show atm vc [vcd | interface interface-number]

Syntax Description

vcd

(Optional) Specifies which virtual circuit about which to display information.

interface interface-number

(Optional) Interface number or subinterface number of the PVC or SVC. Displays all PVCs and SVCs on the specified interface or subinterface.

The interface-number uses one of the following formats, depending on what router platform you are using:

· For the AIP on Cisco 7500 series routers; For the ATM port adapter, ATM-CES port adapter, and enhanced ATM port adapter on Cisco  7200 series routers; For the 1-port ATM-25 network module on Cisco  2600 and 3600 series routers: slot/0[.subinterface-number multipoint]

· For the ATM port adapter and enhanced ATM port adapter on Cisco 7500 series routers: slot/port-adapter/0[.subinterface-number multipoint]

· For the NPM on Cisco 4500 and 4700 routers: number[.subinterface-number multipoint]

For a description of these arguments, refer to the interface atm command.

Command Mode

Table 16 describes the fields shown in the display.


Table 16: Show Interface CBR Field Descriptions
Field Description

CBR6/0 is...

Type, slot, and port number of the interface and indicates whether the interface hardware is currently active (whether carrier detect is present), down, or if it has been taken down by an administrator.

line protocol is...

Indicates whether the software processes that handle the line protocol think the line is usable (that is, whether keepalives are successful). Values are up, down, or administratively down.

Hardware is...

Hardware type.

MTU

Maximum transmission unit of the interface.

BW

Bandwidth of the interface in kilobits per second.

DLY

Delay of the interface in microseconds.

rely

Reliability of the interface as a fraction of 255 (255/255 is 100% reliability), calculated as an exponential average over 5 minutes.

load

Load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes. The calculation uses the value from the bandwidth interface configuration command.

Encapsulation

Encapsulation method assigned to interface.

loopback not set

Indicates whether or not loopback is set.

Last input

Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a dead interface failed.

Last output

Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface.

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in any of the "last" fields exceeds
24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.

Last clearing

The time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) shown in this report were last reset to zero. Note that variables that might affect routing (for example, load and reliability) are not cleared when the counters are cleared.

*** indicates the elapsed time is too large to be displayed.
0:00:00 indicates the counters were cleared more than 231ms (and less than 232ms) ago.

Queueing strategy

First-in, first-out queuing strategy (other queueing strategies you might see are priority-list, custom-list, and weighted fair).

Output queue, drops
input queue, drops

Number of packets in output and input queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped due to a full queue.

5 minute input rate,
5 minute output rate

Average number of bits and packets transmitted per second in the last 5  minutes.

packets input

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

bytes input

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

no buffer

Number of received packets discarded because there was no buffer space in the main system. Compare with ignored count. Broadcast storms on Ethernets and bursts of noise on serial lines are often responsible for no input buffer events.

broadcasts

Total number of broadcast or multicast packets received by the interface.

runts

Number of packets that are discarded because they are smaller than the medium's minimum packet size.

giants

Number of packets that are discarded because they exceed the medium's maximum packet size.

input errors

Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum may not balance with the other counts.

CRC

Cyclic redundancy checksum generated by the originating LAN station or far end device does not match the checksum calculated from the data received. On a LAN, this usually indicates noise or transmission problems on the LAN interface or the LAN bus itself. A high number of CRCs is usually the result of collisions or a station transmitting bad data. On a serial link, CRCs usually indicate noise, gain hits or other transmission problems on the data link.

frame

Number of packets received incorrectly having a CRC error and a noninteger number of octets.

overrun

Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.

ignored

Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different than the system buffers mentioned previously in the buffer description. Broadcast storms and bursts of noise can cause the ignored count to be incremented.

abort

Illegal sequence of one bits on the interface. This usually indicates a clocking problem between the interface and the data link equipment.

packets output

Total number of messages transmitted by the system.

bytes

Total number of bytes, including data and MAC encapsulation, transmitted by the system.

underruns

Number of times that the transmitter has been running faster than the router can handle. This may never be reported on some interfaces.

output errors

Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, as some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.

collisions

Because collisions do not occur on CBR interfaces, this statistic is always zero.

interface resets

Number of times an interface has been reset. The interface may be reset by the administrator or automatically when an internal error occurs.

output buffer failures

Number of no resource errors received on the output.

output buffers swapped out

Number of packets swapped to DRAM.

Usage Guidelines

This command first appeared in Cisco IOS Release 12.0.

This command applies to Voice over ATM on the Cisco MC3810.

The vbr-rt command configures traffic shaping between voice and data PVCs. Traffic shaping is required so that the carrier does not discard calls. To configure voice and data traffic shaping, you must configure the peak, average, and burst options for voice traffic. Configure the burst value if the PVC will be carrying bursty traffic. The peak, average, and burst values are needed so the PVC can effectively handle the bandwidth for the number of voice calls. To calculate the minimum peak, average, and burst values for the number of voice calls, use the following calculations:


Note When you configure data PVCs that will be traffic shaped with voice PVCs, use the aalsnap encapsulation and calculate the overhead as 1.13 times the voice rate.

Example

The following example configures the traffic shaping rate for ATM PVC 20 on a Cisco MC3810. In the example, the peak, average and burst rates are calculated based on a maximum of 20 calls on the PVC.

pvc 20
  encapsulation aal5mux voice
