Recovering from
Problems
Use the following procedure to recover from operating problems or
module failure. Each of these steps is explained in more detail in the
sections that follow.
1
Verify that the DMM can communicate with the ATM Backbone
SwitchModule
2
Verify that the correct software versions are installed.
3
Verify that the critical configuration parameters settings of the ATM
Backbone SwitchModule match those of the ATM switch to which it is
connected.
4
Verify ATM OC-3 Card Functions.
5
Verify ATM Signalling Functions.
6
Verify LEC Functions.
7
Verify Bridging Configuration.
8
Verify that a CoreBuilder 5000 SwitchModule has a vbridge configured
on the same bridge port as the CoreBuilder 5000 ATM Backbone
SwitchModule bridge port.
9
Verify Data Movement.
10
Verify ATM OC-3 Switchover Functions.
Record your results for the following procedures. The information may
be required if you need to contact your technical support
representative.
Verifying DMM
Communication
To isolate a problem in the ATM Backbone SwitchModule, you must be
able to communicate with the ATM Backbone SwitchModule from the
DMM.
Use the following command to verify that the DMM can communicate
with the ATM Backbone SwitchModule:
CB5000> show module all
Check that the display lists the ATM Backbone SwitchModule model
number (6602M-MOD).
