Subject: Troubleshooting Etherchannel
Hi experts,
Are there any commands to troubleshoot etherchannel other than the "show
etherchannel..." set of commands? Like some debug commands that may be
helpful to identify the reason a bundle is not coming up
Also, could anybody provide a brief of the possible reasons an etherchannel
goes into I, s, u or w states? Or point me to some documentation where these
flags, as well as their causes are explained?
Thanks in advance,
Jorge
