Viewing the Counters to see that the Network Traffic is Reaching the Device
In an 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 2000 for both Rx and Tx.
However, in external switch topologies, the counters for the Tx do not increment, that is, Tx does not have a function in monitoring traffic, as it is disconnected.
To view the Fast Ethernet port status, complete the following steps:
Step 1 At the SCE 2000# prompt, type show interface FastEthernet
This displays the port link and auto-negotiation status.
EXAMPLE:
The following example displays a system response.
SCE 2000#show interface FastEthernet 0/1
Auto negotiation configured: Enabled
Actual Status:
Link is on
Auto negotiation: Enabled
Bandwidth: 100000Kbps
To view the FastEthernet counters, complete the following steps:
Step 1 At the SCE 2000# prompt, type show interface FastEthernet
counters.
This displays the FastEthernet counters. This command enables you to verify that traffic is taking place. You can see that the counters increase, together with the increased number of packets that flow through the SCE 2000.
Again, in inline topology, both the Rx and Tx counters apply as traffic monitors. For
EXAMPLE:
The following example shows the counters of the first Fast Ethernet interface.
|
| SCE 2000#show interface FastEthernet 0/1 counters | |
|
| In total octets: 100 | |
|
| In good unicast packets: 90 | |
|
| In good multicast packets: 0 | |
|
| In good broadcast packets: 10 | |
