Completing the Installation

This module explains how to verify link connectivity and how to install a Cisco service control application.
Examining the LEDs
• The GBE Link LED should be green. This indicates 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 2000 platform,
respectively.
In an inline topology, the RX and TX LEDs indicate that packets are being received and transmitted by the SCE
Note
2000 platform.
• In optical splitter topologies, the RX LEDs are the sole indicators. The TX LEDs do not blink, because the TX is not
connected to the port in this topology.
Performing Final Installation Verification
Viewing Gigabit Ethernet Port Status
At the SCE> prompt, type show interface GigabitEthernet 0/portnumber.
Step 1
This displays the port link status.
The following example shows how to display a system response.
SCE>show interface GigabitEthernet 0/1
Auto negotiation configured: Enabled
Actual status:
Link is: ON
Auto negotiation: Enabled
Bandwidth (L1): 1000000 Kbps, Burst-size: 50000 bytes
Pseudo IP Address: Not Configured
physical mode : 0
Monitoring Traffic Using the Gigabit Ethernet Counters
In an inline topology, you can monitor traffic through the platform counters for both the RX and TX connections. As packets
flow through the Cisco SCE 2000 for both RX and TX, the counters increase.
However, in receive-only topologies, the counters for the TX do not increment because the SCE 2000 is only monitoring traffic,
and not re-transmitting traffic.
Step 1 At the SCE> prompt, type show interface GigabitEthernet 0/portnumber counters. The GigabitEthernet counters
appear.
Use the output to verify that traffic is taking place. You can see that the counters increase, together with real-time packet
Step 2
flow through the Cisco SCE 2000.
Remember, in bump-in-the-wire topology, both the RX and TX counters function as traffic monitors. For receive-only
topologies using an external splitter, only the RX counters apply.
