Chapter 4 Configuring the PA-A2 ATM CES Port Adapter

Troubleshooting the PA-A2 ATM CES Port Adapter Installation and Configuration

•

Use the debug atm errors command to display errors. The command displays information from all
detected ATM errors. This includes such errors as encapsulation failures and errors during ATM
configuration.

Router# debug atm errors

•

Use the debug atm events command to display ATM events. The command displays event changes
to the PA-A2 ATM CES port adapter; reset, VC configurations, and PA-A2 ATM CES port adapter
configurations are displayed.

Router# debug atm events

•

Use the debug atm oam command to display information about OAM cells. The command displays
the contents of OAM cells as they arrive from the network.

Router# debug atm oam

Use the no debug command to turn off debugging after using a debug command.

Displaying ATM Information

You can use atm show commands to display the current state of the ATM network and the connected
VCs.

•

Use the show atm vc [vcd] command to show current VCs and traffic information. Specifying a
VCD displays specific information about that VCD.

Router# show atm vc [vcd]

•

Use the show atm interfaces command to show current information about an ATM interface. The
command displays ATM-specific information about an interface.

Router# show atm interfaces

•

Use the show atm traffic command to show current ATM traffic. The command displays global
information about traffic to and from all ATM networks connected to the router.

Router# show atm traffic

•

Use the show atm map command to show the current ATM mapping. The command displays the
active list of ATM static maps to remote hosts on an ATM network.

Router# show atm map

Use the show atm vc command to display the following types of statistics for all PVCs:

Router# show atm vc
