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 0/interface-number.

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

Burst-size: 50000bytes

Auto-negotiation for an inline topology may be enabled or disabled. For receive-only topologies

using an external switch, auto-negotiation must be disabled.

To view the FastEthernet counters, complete the following steps:

Step 1 At the SCE 2000# prompt, type show interface FastEthernet 0/interface-number

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 receive-only

topologies, using an external switch, only the Rx counters apply.

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

1 2 ... 89 90 91 92 93 94 95 96 97 98 99 ... 130 131
