Troubleshooting Overview
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
GBE 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 GigabitEthernet 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)
• Peer does not receive traffic from SCE 2000 (GBE link is lit and Tx LED is flashing)
CLI command: show ip
route
<host-ip-address>
Routing tables are
incorrectly configured
(when the host used as
client is not in the same
network as the SCE
Platform, and there is
more than one gateway
on the SCE Platform
network).
Check / reconfigure
routing tables. See
