ESX and VMWARE - LACP and Cisco 6506

Hello Everyone,

As anyone been able to configure ESX 2.5.1 to use Etherchannel?

VMWARE’s documentation claims that ESX supports LACP to create an EtherChannel. As per VM support I have configured my ESX server correctly and it should use LACP establish an Etherchannel. However on my switch, I see no evidence of LCAP traffic of connectivity via the port-channel. See below for output.

Has anyone here, in the cisco community, got this to work? If yes, would you please advise and share sample configuration.

Regards

Re: ESX and VMWARE - LACP and Cisco 6506

We will now include the commands necessary to configure LACP. The steps include the Cisco IOS Software and CatOS commands required. Pick the appropriate command depending on the software that is running on the switch.

Re: ESX and VMWARE - LACP and Cisco 6506

Have you tried changing LACP on the ESX to be active, and not passive? I have encountered issues with other vendors implementation of LACP even though all documentation suggest ACTIVE-PASSIVE "should" work. I don't see partner state field in show lacp neigh??Sorry, I have no specific info on ESX configuration.
