Troubleshooting PVP and PVC Connections
Checking the VBR and CBR Resources
Use the following commands to confirm the VBR and CBR resources of the configured PVP:
The Catalyst 5000 and 6000 ATM modules do not support the show atm interface resource atm
command. To check the status of a virtual connection on a Catalyst 5000 or 6000 ATM module, use the
show atm vc command. For detailed information about configuring traffic shaping on the Catalyst 5000
and 6000 ATM modules, see the ATM Configuration Guide and Command Reference: Catalyst 5000
and 6000 ATM Modules.
The following example shows the status for all configured VCs on a Catalyst 5000 or 6000 ATM module:
ATM-5500# show atm vc
AAL / Peak Avg. Burst
Interface VCD VPI VCI Type Encapsulation Kbps Kbps Cells Status
0.1 1 0 1 PVC AAL5-SNAP 155000 100000 0 ACTIVE
0 2 0 16 PVC AAL5-ILMI 0 0 0 ACTIVE
ATM-5500#
The following example shows how to display the status for a specific VCD on a Catalyst 5000 or 6000
ATM module:
ATM-5500# show atm vc 1
ATM0.1: VCD: 1, VPI: 0, VCI: 1, etype:0x0, AAL5 - LLC/SNAP, Flags: 0x830
PeakRate: 155000, Average Rate: 100000, Burst Cells: 0, VCmode: 0x0
OAM frequency: 60 second(s), InARP DISABLED
InPkts: 20972, OutPkts: 6924, InBytes: 6778670, OutBytes: 6210607

Debugging the PVC Connection Management
Use the following commands to debug the PVC connection management:
Command Purpose
show atm interface resource atm
card/subcard/port
For UBR connections, confirms CAC
best-effort-limit configuration.
show atm resource For VBR and CBR connections, confirms
that the resources requested are available.
Command Purpose
debug atm conn errors Enables connection management error
debugging.
debug atm conn events Enables connection management event
debugging.
no debug all Disables all debugging.
