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 1000 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 1000 or there is actually no traffic on the line,
which could be a normal situation).
In CLI commands of Gigabit Ethernet interfaces, # stands for the number of the interface. This can be 1

Problem Solving Using a Subsystems Approach
Possible Cause
Default gateway is
incorrect (when the host
used as client is not in
the same network as the
SCE Platform).
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).
Host is not a member of
a valid access-list.
Telnet connection may
be timing out.
