Re: Etherchannel bundle

Hi Bhushan,

Etherchannel bundle of mixed media(copper & fiber) will work fine as long as the ports capability and configuration is fine.

The error message which you are getting is related to GLBP configuration.

Have a look at the explaination from one of the doc

Duplicate address [IP_address] on [chars], sourced by [enet]

Explanation

The IP address in a GLBP message received on the interface is the same as the IP address of the router. This condition may be because of misconfiguration or because of a malfunctioning switch.

Recommended Action

Check the configurations on all the GLBP routers, and ensure that any switches you have are functioning properly.
