This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

12.2(33)SRD1

This command was introduced to display BITS clock information for the 7600-ES+ITU-2TG and 7600-ES+ITU-4TG.

Usage Guidelines

On the Cisco MC3810, this command applies to Voice over Frame Relay, Voice over ATM, and Voice over HDLC. 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 shownetwork-clocks command, you can display the clocking configuration status.

On the Cisco 7600 series routers, this command applies to the following:

  • The clock source from the POS SPAs on the SIP-200 and the SIP-400.

  • The 24-Port Channelized T1/E1 ATM CEoP SPA and the 1-Port Channelized OC-3 STM1 ATM CEoP SPA on the SIP-400.

  • The 7600-ES+ITU-2TG and 7600-ES+ITU-4TG line cards.

Examples

The following is sample output from the shownetwork-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 shownetwork-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 shownetwork-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.

The following is another sample output from the shownetwork-clocks command for the 7600-ES+ITU-2TG or 7600-ES+ITU-4TG:

Router# show network-clocks 
 Active source = Slot 1 BITS 0
 Active source backplane reference line = Primary Backplane Clock

Cisco IOS XE Release 2.3

This command was integrated into Cisco IOS XE Software Release 2.3 and implemented on the Cisco ASR 1000 series routers.

Usage Guidelines

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests for the specified notification types. ATM notifications are defined in the CISCO-IETF-ATM2-PVCTRAP-MIB.my file, available from the Cisco FTP site at ftp:/​/​ftp.cisco.com/​pub/​mibs/​v2/​

ATM PVC failure notifications are sent when a PVC on an ATM interface fails or leaves the UP operational state. Only one trap is generated per hardware interface, within the specified interval defined by the interval keyword (stored as the atmIntfPvcNotificationInterval in the MIB). If other PVCs on the same interface go DOWN during this interval, traps are generated and held until the fail interval has elapsed. When the interval has elapsed, the traps are sent if the PVCs are still DOWN.

No notifications are generated when a PVC returns to the UP state after having been in the DOWN state. If you need to detect the recovery of PVCs, you must use the SNMP management application to regularly poll your router.

The snmp-server enable traps atm pvccommand is used in conjunction with the snmp-server hostcommand. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send notifications, you must configure at least one snmp-server hostcommand.

Examples

The following example shows the enabling of ATM PVC traps on a router, so that if PVC 0/1 goes down, host 172.16.61.90 will receive the notifications:

!For ATM PVC Trap Support to work on your router, you must first have SNMP support and 
!an IP routing protocol configured on your router:

12.2(33)SRE

This command was integrated into Cisco IOS Release 12.2(33)SRE.

Usage Guidelines

For PVCs that are not part of a range, extended ATM PVC traps include virtual path identifier/virtual channel identifier (VPI/ VCI) information, the number of state transitions a PVC goes through in an interval, and the timestamp for the start and end of the transitions. For PVCs that are part of a range, extended ATM PVC traps include the first and last VPI/VCI of the range and the timestamp for the first failure and the last failure within the same range.

Extended ATM PVC and ATM OAM F5 CC traps cannot be used at the same time as the legacy ATM PVC trap. The legacy ATM PVC trap must be disabled by using the no snmp-server enable traps atm pvc command before extended ATM PVC traps can be configured.

The extended ATM PVC failure trap (which is enabled by the snmp-server enable traps atm pvc extension down command) is the same trap as the legacy ATM PVC failure trap (which is enabled by the snmp-server enable traps atm pvc command), but with the following differences:

  • The extended ATM PVC failure trap contains information in the form of VPI/VCI ranges.

  • The extended ATM PVC failure trap contains timestamps for when PVCs go down.

  • The legacy ATM PVC failure trap contains only one VPI/VCI per trap.


Note


You must configure the snmp-server enable traps atm pvc extension mibversion 2command before you can enable the ATM OAM F5 AIS/RDI failure traps, the end-to-end ATM OAM F5 CC failure traps, the OAM failure loopback traps, and the segment ATM OAM F5 CC failure traps. This command enables the MIB that supports these traps.


OAM management must be enabled on the PVC before you can use ATM PVC traps. To generate F5 loopback failure traps, enable OAM management using the oam-pvc manage command. To generate segment F5 CC failure traps, enable segment OAM CC management by using the oam-pvc manage cc segment command. To generate end-to-end F5 CC failure traps, enable end-to-end OAM CC management by using the oam-pvc manage cc end command. To generate OAM F5 AIS/RDI failure traps, enable any of the three types of OAM management listed above.

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests for the specified notification types. The interval between successive traps is 30 seconds.

The extended ATM PVC notifications for MIB version 1 are defined in the CISCO-IETF-ATM2-PVCTRAP-MIB.my file.The extended ATM PVC notifications for MIB version 2 are defined in the CISCO-ATM-PVCTRAP-EXTN-MIB.my file. Both of these MIB files are available from the Cisco FTP site at ftp:/​/​ftp.cisco.com/​pub/​mibs/​v2/​ .

ATM PVC traps are generated at the end of the notification interval. It is possible to generate all three types of ATM PVC traps (the ATM PVC failure trap, ATM PVC up trap, and ATM PVC OAM failure trap) at the end of the same notification interval; however, only one type of trap will be generated for each PVC.

The snmp-server enable traps atm pvc extensioncommand is used in conjunction with the snmp-server hostcommand. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. In order to send notifications, you must configure at least one snmp-server hostcommand.

When the ATM OAM F5 loopback, AIS/RDI, or CC failure trap is enabled, the PVC remains in the UP state when an OAM loopback, AIS/RDI, or CC failure is detected, so that the flow of data will still be possible. If one of these traps is not enabled, the PVC will be placed in the DOWN state when an OAM loopback, AIS/RDI, or CC failure is detected.

Examples

Examples

The following example shows all three of the extended ATM PVC traps enabled on a router. If PVC 0/1 leaves the UP state, leaves the DOWN state, or has an OAM loopback failure, host 172.16.61.90 will receive the SNMP notifications:

Examples

The following example shows output for extended ATM PVC failure trap for PVCs 1/100, 1/102, and 1/103. Note that only one trap is generated for all the PVCs associated with the same interface or subinterface (in contrast to the legacy ATM PVC failure trap, which generates a separate trap for each PVC). The VPI/VCI information and timing information are located in the objects associated with the trap.

This command was integrated into Cisco IOS Release 12.2(33)SXH.

12.2(33)SRE6

This command was modified. To enable the sending of ATM subinterface SNMP notifications, after this command is configured in global configuration mode, the snmp trap link-status command must be configured on each ATM subinterface.

15.1(3)S3

This command was integrated in Cisco IOS Release 15.1(3)S3.

Usage Guidelines

The snmp-server trap link ietf command must be configured in order to use the snmp-server enable traps atm subif command. The snmp-server trap link ietf command is used to configure a router to use the RFC 2233 IETF standards-based implementation of linkUp/linkDown traps. The default Cisco object definitions do not generate linkUp/linkDown traps correctly for subinterfaces.

In order to enable SNMP notifications for ATM subinterfaces, after the snmp-server enable traps atm subif command has been configured in global configuration mode, the snmp trap link-status command must be configured on each ATM subinterface for which you want to enable SNMP notifications.

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests for the specified notification types.

ATM subinterface traps are sent to the network management system (NMS) when a subinterface enters or leaves the down state.

To prevent trap storms, the count and interval keywords can be configured to limit the number of traps and the frequency at which they are sent. Configuring an interval of 0 seconds causes all ATM subinterface traps to be sent.

You can disable ATM subinterface traps by using the no snmp-server enable traps atm subif command. When traps are disabled, you can use the SNMP management application to poll your router for subinterface status information.

The snmp-server enable traps atm subif command is used in conjunction with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send notifications, you must configure at least one snmp-server host command.

By default (when the snmp-server enable traps atm subif command is not configured), the ifLinkUpDownTrapEnable object returns disabled(2), and no traps are generated for the subinterfaces.

When the snmp-server enable traps atm subif command is configured, the ifLinkUpDownTrapEnable object is set to enabled(1) for all the ATM AAL5 layers of the subinterfaces. To verify that the traps are generated (with the debug snmp packets command enabled), enter the shutdown or no shutdown commands to display the traps.

Configuring the snmp trap link-status command on a subinterface generates the traps and sets the ifLinkUpDownTrapEnable object to enabled(1). If the snmp trap link-status command is not configured on the subinterface, the ifLinkUpDownTrapEnable object is set to disabled(2) for that subinterface, and the shutdown or no shutdown commands no longer generate traps for that subinterface.

Examples

The following example shows how to enable ATM subinterface traps on a device. If an ATM subinterface on this device changes state, host 172.16.61.90 will receive the notifications.

! For ATM subinterface trap to work on your router, you must first have SNMP support and 
! an IP routing protocol configured on your router.
Device(config)# snmp-server community public ro

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

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 nameor 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 interface.


Examples

Examples

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

interface atm 2/0/0
  svc chicago

Examples

svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05

Examples

The following example creates an active CES SVC named “ces1”:

12.2(33)SRA

This command was integrated into Cisco IOS Release 12.2(33)SRA.

Usage Guidelines

By default, permanent virtual circuits (PVC) and switch virtual circuits (SVCs) that are created on PA-A3 ATM port adapters and ATM shared port adapters (SPA) use a default transmit priority level that depends on the VC’s or PVC’s configured quality of service (QoS) class. The following table lists the default transmit priority levels for each type of service class.

Table 17 Default Transmit Priorities for Each ATM Service Class

1 CBR=Constant Bit Rate
2 OAM=Operation, Administration, and Maintenance
3 AAL5=Asynchronous Transfer Mode Adaption Layer 5
4 AAL2=Asynchronous Transfer Mode Adaption Layer 2
5 VoATM=Voice over ATM
6 VBR-rt=Variable Bit Rate-Real Time
7 VBR-nrt=Variable Bit Rate-Non-Real Time
8 ABR=Available Bit Rate
9 UBR=Unspecified Bit Rate

To change these default transmit priority levels for a particular VC or PVC, use the transmit-priority command.

The transmit-priority command is not supported in the following cases:

  • The PA-A3 ATM port adapters reserve priority 0 (the highest) for CBR traffic and for OAM and other control cells. You cannot change the transmit priority for this traffic. You also cannot configure other service classes for priority 0.

  • You cannot use the transmit-priority command for VCs on a shaped virtual path (VP) on an ATM SPA

  • The PA-A3-OC12 port adapter does not support the transmit-priority command.


Tip


Use the show atm pvc and show atm svc commands to display the current transmit priority for a PVC or SVC.


Examples

The following example shows the transmit-priority command being used to change the priority for a PVC on a PA-A3 ATM port adapter. The PVC is configured for the VBR-rt service class, which has a default transmit priority level of 2, but the transmit-priority command changes the priority level to 3:

Router# configure terminal
 
Router(config)# interface atm 3/0.10
 
Router(config)# pvc 10/1
 
Router(config-if-atm-vc)# vbr-rt 48 48
 
Router(config-if-atm-vc)# transmit-priority 3
 
Router(config-if-atm-vc)# end
 
Router# 

The following example shows the transmit-priority command being used to change the priority for a PVC on an ATM SPA. Because the PVC defaults to the UBR service class, its default transmit priority is configured to 6, but the transmit-priority command changes the priority level to 4:

Router# configure terminal
 
Router(config)# interface atm 4/1/3
 
Router(config-if)# pvc 1/100
 
Router(config-if-atm-vc)# transmit-priority 4
 
Router(config-if-atm-vc)# end
 
Router# 

Note


The maximum configurable transmit priority through VC class is 6, but only on an IMA interface the maximum applicable transmit priority level is 4. If you configure more than the applicable transmit priority, the priority level falls back to the maximum applicable transmit priority.

Modification

12.2(18)SXE

This command was introduced for the ATM Shared Port Adapters (SPA) on Catalyst 6500 series switches and Cisco 7600 series routers.

12.2(33)SRA

This command was integrated into Cisco IOS Release 12.2(33)SRA.

Usage Guidelines

When you configure a VC on an ATM SPA interface, the Cisco IOS software automatically determines the maximum number of transmit buffers that are needed by the VC for its outgoing traffic. The Cisco IOS software uses both the configured VC line rate and latency value to calculate the number of buffers. Each transmit buffer can contain an ATM cell (53 bytes).

By default, each VC uses the latency value that is specified by the atm tx-latency command, which defaults to 100 milliseconds. The maximum number of transmit buffers is then calculated, so that traffic at the maximum VC line rate can still be transmitted within this latency value.

If a particular VC’s traffic flow requires a different latency value, use the tx-limit command to manually configure the number of transmit buffers for that VC. This allows you to fine-tune the latency value on a per-VC basis, without affecting the other VCs on the interface.


Tip


Use the atm tx-latency command to specify the default latency value for all VCs on the interface, and then use the tx-limit command to fine-tune the configuration for a particular VC, as needed.



Note


The number of buffers can also be affected by the packet size, because each VC is always allowed to transmit at least one packet, regardless of the number of buffers configured with the tx-limit command. If the number of buffers specified by the tx-limit command is very small, and the VC must transmit a very large packet, the interface can increase the number of buffers for the VC to whatever number can accommodate the packet’s size. This means that occasionally, the number of buffers can grow to whatever number can accommodate a packet up to the maximum MTU size.



Note


Other ATM interfaces have used the tx-ring-limit command to achieve a similar result, but this command is not supported on ATM SPA interfaces, because it does not apply to the SPA architecture.


Examples

The following example shows an ATM VC being configured for a maximum of 500 buffers:

Router# configure terminal
 
Router(config)# interface atm 4/0/0.10 point-to-point
 
Router(config-subif)# pvc 10/101
 
Router(config-if-atm-vc)# tx-limit 500
 
Router(config-if-atm-vc)# 

The following example shows an ATM VC being reset for its default buffer value, which will be whatever buffer size is needed, at the VC line rate, to produce a default latency of 100 milliseconds (or whatever value is specified by the atm tx-latency command):

Router# configure terminal
 
Router(config)# interface atm 3/0/1.10 point-to-point
 
Router(config-subif)# pvc 10/20
 
Router(config-if-atm-vc)# no tx-limit 
Router(config-if-atm-vc)#

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 ubrcommand 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-bundleconfiguration 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

This command was implemented on the Cisco AS5300 and Cisco AS5850.

Cisco IOS XE Release 2.3

This command was made available in ATM PVP configuration mode.

Usage Guidelines

This 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 carry bursty traffic. Peak, average, and burst values are needed so that the PVC can effectively handle the bandwidth for the number of voice calls.

Calculate the minimum peak, average, and burst values for the number of voice calls as follows:

Peak Value

Peak value = (2 x the maximum number of calls) x 16K = _______________

Average Value

Calculate according to the maximum number of calls that the PVC will carry times the bandwidth per call. The following formulas give you the average rate in kbps:

  • For VoIP:
    • G.711 with 40- or 80-byte sample size:

Average value = max calls x 128K = _______________

    • G.726 with 40-byte sample size:

Average value = max calls x 85K = _______________

    • G.729a with 10-byte sample size:

Average value = max calls x 85K = _______________

  • For VoATM adaptation layer 2 (VoAAL2):
    • G.711 with 40-byte sample size:

Average value = max calls x 85K = _______________

    • G.726 with 40-byte sample size:

Average value = max calls x 43K = _______________

    • G.729a with 10-byte sample size:

Average value = max calls x 43K = _______________

If voice activity detection (VAD) is enabled, bandwidth usage is reduced by as much as 12 percent with the maximum number of calls in progress. With fewer calls in progress, bandwidth savings are less.

Burst Value

Set the burst size as large as possible, and never less than the minimum burst size. Guidelines are as follows:

  • Minimum burst size = 4 x number of voice calls = _______________

  • Maximum burst size = maximum allowed by the carrier = _______________

When you configure data PVCs that will be traffic shaped with voice PVCs, use AAL5snap encapsulation and calculate the overhead as 1.13 times the voice rate.

Examples

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

pvc 20
