Connecting the line ports to the network
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 in order 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
To view the Gigabit Ethernet port status:
Step 1 Type show interface Gigabit Ethernet 0/interface number.
This displays the port link and
EXAMPLE:
The following example displays a system response.
SCE 1000#show interface Gigabit Ethernet 0/1
Auto negotiation configured: Enabled
Actual Status:
Link is on, Auto negotiation: Enabled,
Bandwidth: 100000Kbps,
Again,
To view the Gigabit Ethernet counters:
Step 1 Type show interface Gigabit Ethernet 0/interface counters.
