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)
