GBE Interfaces Connectivity

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 GigabitEthernet interfaces, # stands for the number of the interface. This can

be 1 or 2.
