Troubleshooting/debugging Port/Etherchannels

Hi guys,

Is there a way to check on the status of your Port/Etherchannel other than running 'sh in po1' etc?

The reason I ask is that some of our switches have a really high utilisation and Im am just working through the configs of such. In some cases the configuration that is specified for the physical interfaces that make up the respective channel are also configured (and in some cases) incorrectly in the logical port channels.

Any suggestions?

Hi Darren,

You can also use the following commands:

show ether-channel port-channel

show ether-channel summary [detail]

These will show you the component physical ports as well that make up the ether-channel and a lot of other useful information.

Hi Darren,

If you want to find out the reason for high cpu utilization, a good start would be to find out what processes are using the most cpu time:

show processes cpu sorted

show processes cpu history
