Etherchannel on Cisco IOS Catalyst Switch

Hi Rene and Andrew,

I have configured a L2 etherchannel by using the following commands

On the 1st switch, i issue

  1. conf t
  2. int range fa0/23-24
  3. channel-group 1 mode on;

The 2 lines went up and the port-channel got created and up.
This was done on only 1 side of the switch but show etherchannel summary show the PO1 (SU) – layer2 and in use.
Subsequently, i went to setup the same on the 2nd switch.

Q1) My question is , how do we verify that the port-channel connectivity between the 2 switches are really working (given that it turn ups even only when 1 side of the switch is configured).

Q2) I have configure src-dst mac load-balancing, but other then using “test etherchannel load-balance”, is there anyway way to see the traffic distribution between the 2 interface/lines on the switch ?
I do a show int fa0/23; and show int fa0/24, trying to a get baseline of the current traffic on both interfaces before sending some packets out, but the output packets on both interfaces jumps all the time before i even actually send the actual traffic out.

How do i verify that both links are actually “used” ?

Regards,
Alan
