Testing Connectivity: Examining Link LEDs and Counters

Verify that the link LED is green.
Step 2
If the link LED does not light, try removing the network cable plug and reinserting it firmly into the
module socket.

Testing Connectivity: Examining Link LEDs and Counters

If the SCE 1000 platform has been powered up, test now to verify that connectivity has been established
on all links. If the SCE 1000 platform is not powered up, perform this step after starting the SCE 1000
platform.

Examining the LEDs

The GBE Link LED must be green to verify that an active connection exists.
The GBE Rx and Tx LEDs (if flashing green) indicate that traffic is being received or transmitted by the
SCE 1000 platform, respectively.
Note that in an inline topology, the Rx and Tx LEDs indicate that packets are being received/transmitted
by the SCE 1000 platform.
In optical splitter topologies, the Rx LEDs are the sole indicators. The Tx LEDs do not "blink", since
the Tx is not connected to the port in this topology.

Viewing the Counters to See that the Network Traffic is Reaching the Device

In inline topology, you can monitor traffic via the platform counters for both the Rx and Tx connections.
The counters increase, together with the increased number of packets that flow through the SCE 1000
for both Rx and Tx.
However, in receive-only topologies, the counters for the Tx do not increment, that is, Tx does not have
a function in monitoring traffic, as it is disconnected.
How to View the Gigabit Ethernet Port Status
At the SCE 1000# prompt, type show interfaceGigabitEthernet 0/ interface-number.
Step 1
This displays the port link and auto-negotiation status.
