Multichasis Etherchannel

I am configuring Multichasis LAG between cisco 3750 and Alcatel 7450ESS.Etherchannel is showing up on both sides but no traffic passing through.Also after 15 minutes the interfaces becomes err-disabled on cisco side with message"Channel misconfigured error detected"

I Checked found no misconfiguration.

Any idea has anyone tried this setup???

Re: Multichasis Etherchannel

If you are running Native, you can enable the etherchannel misconfig guard by using the below command. This is not enabled by default.

"spanning-tree etherchannel guard misconfig"

For the configuration of Etherchannel follow the link :
