scrambling cell-payload

To improve data reliability by randomizing the ATM cell payload frames on Cisco 7100, 7200, or 7500 series routers, use the scrambling cell-payload command in interface configuration mode. To disable scrambling, use the no form of this command.

scrambling cell-payload

no scrambling cell-payload

Syntax Description

This command has no arguments or keywords.

Defaults

No scrambling

Command Modes

Interface configuration

Command History

Release	Modification
12.0(5)XE	This command was introduced.
12.0(7)XE1	Support for Cisco 7100 series routers added.
12.1(5)T	This command was integrated into Cisco IOS Release 12.1(5)T.

Usage Guidelines

Normally, you do not issue the scrambling cell-payload command explicitly, because the default value is sufficient. On T1 links, the default b8zs line encoding normally assures sufficient reliability. The default for E1 is hdb3.

The scrambling setting must match that of the far-end receiver.

Examples

On Cisco 7100 or 7200 series routers, the following example sets the link on interface 1 on the port adapter in slot 0 to no scrambling:

interface atm0/1

VPI	Virtual path identifier.
VCI	Virtual channel identifier.
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.

Table 20 describes the fields shown in the display.

Table 20 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.
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 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 21 describes the fields shown in both the displays.

Table 21 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.
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 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 command in privileged EXEC mode.

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 previous 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 [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.

Creating 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.

Note Cisco IOS does not support creation of SVCs on a point-to-point subinterface.

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

Active CES SVC Example

The following example creates an active CES SVC named "ces1":

interface atm 1/0

svc ces1 nsap 47.00.00.000000.0040.0B0A.2501.ABC1.01.01.00 ces

Passive CES SVC Example

The following example creates a passive CES SVC named "ces2":

interface atm 1/0

svc ces2 ces

ubr

To configure unspecified bit rate (UBR) quality of service (QoS) and specify the output peak cell rate (PCR) for an ATM permanent virtual circuit (PVC), PVC range, switched virtual circuit (SVC), virtual circuit (VC) class, or VC bundle member, use the ubr command in the appropriate command mode. To remove the UBR parameter, use the no form of this command.

ubr output-pcr [input-pcr]

no ubr output-pcr [input-pcr]

Syntax Description

output-pcr	The output PCR in kbps.
input-pcr	(Optional for SVCs only) The input peak cell rate (PCR) in kilobits per second. If this value is omitted, the input-pcr will equal the output-pcr.

Defaults

UBR QoS at the maximum line rate of the physical interface.

Command Modes

Interface-ATM-VC configuration (for an ATM PVC or SVC)

VC-class configuration (for a VC class)

Bundle-vc configuration (for ATM VC bundle members)

PVC range configuration (for an ATM PVC range)

PVC-in-range configuration (for an individual PVC within a PVC range)

Command History

Release	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

 ubr 10000 9000

ubr+

To configure unspecified bit rate (UBR) quality of service (QoS) and specify the output peak cell rate and output minimum guaranteed cell rate for an ATM permanent virtual circuit (PVC), PVC range, switched virtual circuit (SVC), virtual circuit (VC) class, or VC bundle member, use the ubr+ command in the appropriate command mode. To remove the UBR+ parameters, use the no form of this command.

ubr+ output-pcr output-mcr [input-pcr] [input-mcr]

no ubr+ output-pcr output-mcr [input-pcr] [input-mcr]

Syntax Description

output-pcr	The output peak cell rate (PCR) in kbps.
output-mcr	The output minimum guaranteed cell rate in kbps.
input-pcr	(Optional for SVCs only) The input PCR in kbps. If this value is omitted, the input-pcr equals the output-pcr.
input-mcr	(Optional for SVCs only) The input minimum guaranteed cell rate in kbps. If this value is omitted, the input-mcr equals the output-mcr.

Command Default

UBR QoS is at the maximum line rate of the physical interface.

VC-class configuration (for a VC class)
Bundle-VC configuration (for ATM VC bundle members)
PVC range configuration (for an ATM PVC range)

Command History

Release	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 and output minimum guaranteed cell rate for ATM VC bundles and VC bundle members.
12.1(5)T	This command was made available in PVC range and PVC-in-range configuration modes.
12.4(2)XA	This command was enabled on DSL ATM interfaces.
12.4(6)T	This command was enabled on DSL ATM interfaces.

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, output-mcr, input-pcr, and input-mcr arguments.

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

If the ubr+ command is not explicitly configured on an ATM PVC or SVC, the VC inherits the following default configuration (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 ATM subinterface or SVC ATM subinterface

•Configuration of any QoS command (ubr, ubr+, or vbr-nrt) in a VC class assigned to the PVC main interface or SVC 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 (meaning a VC that is not a bundle member).

To use this command in bundle-VC configuration mode, enter the bundle command to specify the bundle to which the VC member belongs, then enter bundle configuration mode. Finally, enter the pvc-bundle bundle configuration command to add the VC to the bundle as a member.

VCs in a VC bundle use the following configuration inheritance rules (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

DSL ATM interfaces do not support switched virtual circuits (SVCs).

Examples

The following example configures UBR+ PVC on a DSL line:

interface atm 0/0

 pvc 4/100

  ubr+ 2304 2304




The following example specifies the output-pcr argument for an ATM PVC to be 100000 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 10000 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

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:
