Troubleshooting the Link Interface Subsystem
Check the following to help isolate a problem in the link interface subsystem.
In general, the case where no traffic is coming out of the
SCE 2000
is often caused by link
problems or FE interface configuration. Note that in some cases, the problem which seems as a
transmit problem could be in the Rx (no traffic is being received by the
SCE 2000
or there is
actually no traffic on the line, which could be a normal situation).
Note
In CLI commands of FastEthernet interfaces, # stands for the number of the interface. This can be 1
through 4.
Problems in the link interface subsystem could be any of the following:
•
Link is down. (LINK LED not lit and system status is WARNING)
