LACP across two switches

Is it possible yet to etherchannel (using LACP) from a server using Broadcom NICs (with the latest drivers and software) to two Cisco switches?

I heard that etherchannel has evolved but not sure to what extent. Thanks.

Hello,

I assume you are referring to multichassis LACP Etherchannels, that is, each NIC going into a different switch, and both links forming a channel ?

That is correct. Is it possible yet? Thanks.

Hello,

TMBK, the only way to configure an Etherchannel (wether PAgP or LACP doesn´t matter) is across a stack, because apparently that is the only way the channel group interface knows that it belongs to ports on different physical switches...

I will ask around if that has changed and let you know.

Does that mean that it is possible to configure an etherchannel between a 7206 router and two catalyst 3550 if both switches are linked together with a gigastack gbic ?

Thanks
