Troubleshooting OAM on ATM Router Module Connections
Figure 13-11 ATM Router Module OAM Example Network
This example network is used in the following troubleshooting steps.
Follow these steps to configure and troubleshoot the ATM router module with OAM configured (see the
example network shown in Figure 13-11):
Step 1 At switch router c8540-1, use the following commands to configure the ATM interface connected to
switch router c8540-2, to perform OAM fault management.
c8540-1(config)# interface atm 0/0/0.5 point-to-point
c8540-1(config-subif)# atm pvc 2 105 int atm 0/0/0 0 105
c8540-1(config-subif)# atm oam interfaces atm 0/0/0 0 105 end-loopback
% OAM: Connection level end to end loopback is enabled
c8540-1(config-subif)#
In this example, the system message “% OAM: Connection level end to end loopback is enabled”
appears, indicating the subinterface is correctly enabled.
Step 2 At switch router c8540-1, use the show running-config command to confirm configuration of the ATM
interface connected to switch router c8540-2 and the ATM route module interface.
c8540-1# show running-config
