Jeff,

We use Etherchannel on some of our servers, none of which are TSM servers
(but clients use it) in our case, however.  Your NIC's (or drivers more
accurately) MUST support PAgP, for the channel to be automatically formed.
This is a Cisco protocol that handles the negotiation of the channel and
without it, you will be hard pressed to make the channel work!  Intel NIC's
support PAgP, and I *think* some 3Com ones do, but other than that, I am not
sure...  Contact me directly if you would like more info.

Has anyone set up Gig Etherchannel to a Cisco Switch?
We're about to test this with a P670 on AIX 5.2 with 4 (supported) Gig
Ethernet cards. The question from our Wan group in planning the switch
changes is, "Do we use PAgP or not?". I talked with IBM, who didn't
recognize that protocol. This tells me we're not set up to specifically
recognize it, but I'm still putting the question to the experts. I can't see
how it would hurt, especially based on what the Cisco site says about it,
that it helps in the automatic creation of fast Ethernet Links".

Thanks!!
