show atm vc

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

show atm vc [vcd | interface interface-number]

Syntax Description

vcd

(Optional) Specifies the virtual circuit descriptor (VCD) 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 ATM Interface Processor (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 network processing module (NPM) on Cisco 4500 and Cisco 4700 routers: number[.subinterface-number multipoint]

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

Usage Guidelines

If no value is specified for the vcd argument, the command displays information for all PVCs and SVCs. The output is in summary form (one line per virtual circuit).

VCs on the extended MPLS ATM interfaces do not appear in the show atm vc command output. Instead, the show xtagatm vc command provides a similar output that shows information only on extended MPLS ATM VCs.

Examples

The following is sample output from the show atm vc command when no vcd value is specified. The status field is either ACTIVE or INACTIVE.

Type

Type of VC, either PVC, SVC, TVC, or multipoint SVC (MSVC).

MSVC (with no -x) indicates that VCD is a leaf of some other router's multipoint VC.

MSVC-x indicates there are x leaf routers for that multipoint VC opened by the root.

Type of PVC detected from PVC discovery, either PVC-D, PVC-L, or PVC-M.

PVC-D indicates a PVC created due to PVC discovery.

PVC-L indicates that the corresponding peer of this PVC could not be found on the switch.

PVC-M indicates that some or all of the Quality of Service (QoS) parameters of this PVC do not match those of the corresponding peer on the switch.

TVC indicates a Tag VC.

Encaps

Type of ATM adaptation layer (AAL) and encapsulation.

PeakRate

Kilobits per second sent at the peak rate.

Average Rate

Kilobits per second sent at the average rate.

Burst Cells

Value that equals the maximum number of ATM cells the VC can send at peak rate.

Status of the VC connection.

UP indicates that the connection is enabled for data traffic.

DOWN indicates that the connection is not ready for data traffic. When the Status field is DOWN, a State field is shown.

INACTIVE indicates that the interface is down.

ACTIVE indicates that the interface is in use and active.

etype

Encapsulation type.

Flags

Bit mask describing VC information. The flag values are summed to result in the displayed value.

VCmode

AIP-specific or NPM-specific register describing the usage of the VC. This register contains values such as rate queue, peak rate, and AAL mode, which are also displayed in other fields.

OAM frequency

Seconds between OAM loopback messages, or DISABLED if OAM is not in use on this VC.

InARP frequency

Minutes between Inverse Address Resolution Protocol (InARP) messages, or DISABLED if InARP is not in use on this VC.

virtual-access

Virtual access interface identifier.

virtual-template

Virtual template identifier.

InPkts

Total number of packets received on this VC. This number includes all fast-switched and process-switched packets.

OutPkts

Total number of packets sent on this VC. This number includes all fast-switched and process-switched packets.

InBytes

Total number of bytes received on this VC. This number includes all fast-switched and process-switched packets.

OutBytes

Total number of bytes sent on this VC. This number includes all fast-switched and process-switched packets.

InPRoc

Number of process-switched input packets.

OutPRoc

Number of process-switched output packets.

Receive Ring Limit for this VC.

Transmit priority

ATM service class transmit priority for this VC.

InCells

Number of incoming cells on this VC.

OutCells

Number of outgoing cells on this VC.

InPktDrops

A non-zero value for the InPktDrops of a VC counter suggests that the ATM interface is running out of packet buffers for an individual VC, or is exceeding the total number of VC buffers that can be shared by the VCs.

OutPktDrops

The PA-A3 driver increments the OutPktDrops counter when a VC fills its individual transmit buffer quota. The purpose of the quota is to prevent a consistently over-subscribed VC from grabbing all of the packet buffer resources and hindering other VCs from transmitting normal traffic within their traffic contracts.

InCellDrops

Number of incoming cells dropped on this VC.

OutCellDrops

Number of outgoing cells dropped on this VC.

InByteDrops

Number of incoming bytes that are dropped on this VC.

OutByteDrops

Number of outgoing bytes that are dropped on this VC.

Number of cyclic redundancy check (CRC) errors on this VC.

SarTimeOuts

Number of segmentation and reassembly sublayer time-outs on this VC.

OverSizedSDUs

Number of over-sized service data units on this VC

LengthViolation

Number of length violations on this VC. A length violation occurs when a reassembled packet is dropped without checking the CRC.

CPIErrors

The Common Part Indicator error field is a one octet field in the AAL5 encapsulation of an ATM cell and must be set to 0. If it is received with some other value, it is flagged as an error by the interface. For example, this error may indicate data corruption.

Out CLP

Number of Packets and/or cells where the Output Cell Loss Priority bit is set.

OutAS

Number of autonomous-switched or silicon-switched output packets.

OAM cells received

Number of OAM cells received on this VC.

Table 19 describes the fields shown in the display.

Table 19 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, and 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. This counter is updated only when packets are process switched, not when packets are fast switched.

Last output

Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface. This counter is updated only when packets are process switched, not when packets are fast switched.

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 that the elapsed time is too large to be displayed.
0:00:00 indicates that 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.

Table 20 show interfaces atm Field Descriptions 

Field
Description

ATM... is {up | down|
administratively down}

Indicates whether the interface hardware is currently active (whether carrier detect is present) and if it has been taken down by an administrator.

line protocol
is {up | down |
administratively down}

Indicates whether the software processes that handle the line protocol think the line is usable (that is, whether keepalives are successful).

Hardware is

Hardware type.

Internet address is

Internet address and subnet mask.

MTU

Maximum Transmission Unit of the interface.

sub MTU

Maximum Transmission Unit of the subinterface.

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.

ATM E164 Auto Conversion Interface

Indicates that ATM E164 auto conversion is enabled. When this field is not present, ATM E164 auto conversion is disabled.

Encapsulation

Encapsulation method assigned to interface.

loopback

Indicates whether the interface is configured for loopback testing.

keepalive

Indicates whether keepalives are set or not.

Encapsulation(s)

Type of encapsulation used on the interface (for example, AAL5, and either PVC or SVC mode).

TX buffers

Number of buffers configured with the atm txbuff command.

RX buffers

Number of buffers configured with the atm rxbuff command.

Maximum active VCs

Maximum number of virtual circuits.

VCs per VP

Number of virtual circuits per virtual path (the default is 1024).

Current VCs

Number of virtual circuit connections currently open.

VC idle disconnect time

Number of seconds the SVC must be idle before the SVC is disconnected.

Signalling vc

Number of the signaling PVC.

vpi

Virtual path identifier number.

vci

Virtual channel identifier number.

ATM NSAP address

NSAP address of the ATM interface.

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. This counter is updated only when packets are process switched, not when packets are fast switched.

Last output

Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface. This counter is updated only when packets are process switched, not when packets are fast switched.

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

Queueing strategy

First-in, first-out queueing 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.

Received 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 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

This feature is not applicable for ATM interfaces.

interface resets

Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the transmit clock signal, or by a cable problem. If the system notices that the carrier detect line of a serial interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.

output buffer failures

Number of times that a packet was not output from the output hold queue because of a shortage of MEMD shared memory.

output buffers swapped out

Number of packets stored in main memory when the output queue is full; swapping buffers to main memory prevents packets from being dropped when output is congested. The number is high when traffic is bursty.

restarts

Number of times the controller was restarted because of errors.


show network-clocks

To display the current configured and active network clock sources, use the show network-clocks privileged EXEC command.

show network-clocks

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release
Modification

11.1

This command was introduced.


Usage Guidelines

This command applies to Voice over Frame Relay, Voice over ATM, and Voice over HDLC on the Cisco MC3810.

The Cisco MC3810 has a background task that verifies whether a valid clocking configuration exists every 120 seconds. If this task detects an error, you will be reminded every 120 seconds until the error is corrected. A clocking configuration error may be generated for various reasons. Using the show network-clocks command, you can display the clocking configuration status.

Examples

The following is sample output from the show network-clocks EXEC command.

Router# show network-clocks

Priority 1 clock source: ATM3/0/0
Priority 2 clock source: System clock
Priority 3 clock source: System clock
Priority 4 clock source: System clock

Current clock source:ATM3/0/0, priority:1

The following is sample output from the show network-clocks command on the Cisco MC3810:

Router# show network-clocks

Priority 1 clock source(inactive config): T1 0
Priority 1 clock source(active config) : T1 0
Clock switch delay: 10
Clock restore delay: 10
T1 0 is clocking system bus for 9319 seconds.
Run Priority Queue: controller0

In this display, inactive configuration is the new configuration that has been established. Active configuration is the run-time configuration. Should an error be made in the new configuration, the inactive and active configurations will be different. In the above example, the clock priority configuration is valid, and the system is being clocked as indicated.

The following is another sample output from the show network-clocks command:

Router# show network-clocks

Priority 1 clock source(inactive config) : T1 0
Priority 2 clock source(inactive config) : T1 1
Priority 1 clock source(active config) : T1 0
Clock switch delay: 10
Clock restore delay: 10
T1 0 is clocking system bus for 9319 seconds.
Run Priority Queue: controller0

In this display, the new clocking configuration has an error for controller T1 1. This is indicated by checking differences between the last valid configuration (active) and the new proposed configuration (inactive). The error may result from hardware (the system controller board or MFT) unable to support this mode, or controller T1 1 is currently configured as "clock source internal."

Since the active and inactive configurations are different, the system will periodically display the warning message about the wrong configuration.

svc

To create an ATM switched virtual circuit (SVC) and specify the destination network service access point (NSAP) address on a main interface or subinterface, use the svc interface configuration command. To disable the SVC, use the no form of this command.

svc [name] [nsap address] [ces]

no svc [name] [nsap address] [ces]

Syntax Description

name

(Optional) The name of the SVC and map. The name can be up to 16 characters long. A name is required when creating passive a CES SVC.

nsap address

(Optional) The destination ATM NSAP address. Must be exactly 40 hexadecimal digits long and in the correct format. See the "Usage Guidelines" section. An NSAP address is required when creating an active CES SVC.

ces

(Optional) Circuit Emulation Service encapsulation. This keyword is available on the OC-3/STM-1 ATM Circuit Emulation Service network module only.


Defaults

No NSAP address is defined.

Command Modes

Interface configuration

Command History

Release
Modification

11.3

This command was introduced.

12.1(2)T

The ces keyword was added to configure CES encapsulation when using the OC-3/STM-1 ATM Circuit Emulation Service network module on Cisco 2600 and Cisco 3600 series platform.

12.1(3)T

This command was modified to allow an SVC to be created without having a specific NSAP address associated with it.


Usage Guidelines

After configuring the parameters for an ATM SVC, you must exit the interface-ATM-VC or interface-CES-VC configuration mode in order to enable the SVC settings.

Once you specify a name for an SVC, you can reenter the interface-ATM-VC or interface-CES-VC configuration mode by simply entering svc name.

You can remove an NSAP address and any associated parameters by entering no svc name or no svc nsap address.

ACreating an SVC without a specific NSAP address will allow a router to accept calls from any ATM address, and allow multiple VCs to be set up using the same configuration.

Use the ces keyword to configure an active or passive CES SVC. An active CES SVC can originate and terminate SVC calls. A passive CES SVC can only terminate calls.

Examples

SVC Example

The following example creates an SVC called "chicago" on ATM interface 2/0/0:

interface atm 2/0/0
  svc chicago

SVC with NSAP Address Example

The following example creates an SVC with the name "lion" and specifies the 40-digit hexadecimal destination ATM NSAP address:

svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05

Modification

11.3 T

This command was introduced.

12.0(3)T

This command was enhanced to support selection of UBR QoS and configuration of output PCR for ATM VC bundles and ATM VC bundle members.

12.1(5)T

This command was made available in PVC range and PVC-in-range configuration modes.


Usage Guidelines

To configure ATM SVCs with an output PCR and an input PCR that differ from each other, you must expressly configure an output value and an input value using the output-pcr and input-pcr arguments, respectively.

Configure QoS parameters using the ubr, ubr+, or vbr-nrt command. The last command you enter will apply to the PVC or SVC you are configuring.

If the ubr command is not explicitly configured on an ATM PVC, SVC, or VC bundle member, the VC inherits the following default configuration (listed in order of next highest precedence):

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC or SVC itself.

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC's or SVC's ATM subinterface.

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC's or SVC's ATM main interface.

Global default: UBR QoS at the maximum line rate of the PVC or SVC.

To use this command in VC-class configuration mode, enter the vc-class atm global configuration command. This command has no effect if the VC class that contains the command is attached to a standalone VC, that is, if the VC is not a bundle member.

To use this command in bundle-vc configuration mode, first enter the bundle command to specify the bundle, then enter bundle configuration mode. Then enter the pvc-bundle configuration command to add the VC to the bundle as a member of it and enter bundle-vc configuration mode.

VCs in a VC bundle are subject to the following configuration inheritance rules (listed in order of next highest precedence):

VC configuration in bundle-vc mode

Bundle configuration in bundle mode (with effect of assigned VC-class configuration)

Subinterface configuration in subinterface mode

Examples

The following example specifies the output-pcr argument for an ATM PVC to be 100,000 kbps:

pvc 1/32
 ubr 100000

The following example specifies the output-pcr and input-pcr arguments for an ATM SVC to be 10,000 kbps and 9,000 kbps, respectively:

svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC's or SVC's ATM subinterface.

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC's or SVC's ATM main interface.

Global default: UBR QoS at the maximum line rate of the PVC or SVC.

To use this command in VC-class configuration mode, enter the vc-class atm global configuration command before you enter the ubr+ command. This command has no effect if the VC class that contains the command is attached to a standalone VC, that is, if the VC is not a bundle member.

To use this command in bundle-vc configuration mode, first enter the bundle command to specify the bundle the VC member belongs to, then enter bundle configuration mode. Then enter the pvc-bundle bundle configuration command to add the VC to the bundle as a member of it.

VCs in a VC bundle are subject to the following configuration inheritance rules (listed in order of next highest precedence):

VC configuration in bundle-vc mode

Bundle configuration in bundle mode (with effect of assigned VC-class configuration)

Subinterface configuration in subinterface mode

Examples

The following example specifies the output-pcr argument for an ATM PVC to be 100,000 kbps and the output-mcr to be 3000 kbps:

pvc 1/32
 ubr+ 100000 3000

The following example specifies the output-pcr, output-mcr, input-pcr, and input-mcr arguments for an ATM SVC to be 10,000 kbps, 3000 kbps, 9000 kbps, and 1000 kbps, respectively:

svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05
 ubr+ 10000 3000 9000 1000

Command History

Release
Modification

11.3 T

This command was introduced.

12.0(3)T

This command was enhanced to support configuration of VBR-NRT QoS and specification of output PCR, output SCR, and output maximum burst cell size for ATM bundles and VC bundle members.

12.1(5)T

This command was made available in PVC range and PVC-in-range configuration modes.


Usage Guidelines

Configure QoS parameters using the ubr, ubr+, or vbr-nrt command. The last command you enter will apply to the PVC or SVC you are configuring.

If the vbr-nrt command is not explicitly configured on an ATM PVC or SVC, the VC inherits the following default configuration (listed in order of precedence):

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC or SVC itself.

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC's or SVC's ATM subinterface.

Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC's or SVC's ATM main interface.

Global default: UBR QoS at the maximum line rate of the PVC or SVC.

To use this command in VC-class configuration mode, enter the vc-class atm global configuration command before you enter the vbr-nrt command. This command has no effect if the VC class that contains the command is attached to a standalone VC, that is, if the VC is not a bundle member.

To use this command in bundle-vc configuration mode, first enter the pvc-bundle configuration command to add the VC to the bundle as a member of it, then and enter bundle-vc configuration mode.

VCs in a VC bundle are subject to the following configuration inheritance rules (listed in order of precedence):

VC configuration in bundle-vc mode

Bundle configuration in bundle mode (with effect of assigned VC-class configuration)

Subinterface configuration in subinterface mode

Examples

The following example specifies the output-pcr argument for an ATM PVC to be 100,000 kbps, the output-scr argument to be 50,000 kbps, and the output-mbs to be 64:

pvc 1/32
 vbr-nrt 100000 50000 64

The following example specifies the VBR-NRT output and input parameters for an ATM SVC:

svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05
