Unanswered Question
Aug 15th, 2008

What is the best practice to use when configuring port channel between Catalystr 3750G switch stack and WLC 4402 / 4404 Wireless Lan Controllers?

a) Negotiate to LACP

b) Negotiate to PAgP

or

c) Hard-code to Port Channel without any negotiation.

Any pointers to any useful links - much appreciated and configuration example as well.

I have this problem too.

Hello Alphonse,

I would use a) option LACP because it is standard.

PAGP is Cisco proprietary and is implemented only on Cisco switches

It is so LACP is needed here look at:

http://www.cisco.com/en/US/docs/wireless/controller/5.0/configuration/guide/c5mint.html#wp1113877

Enabling Link Aggregation

Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard

The WiSM module for cat6509 we have do the same use LACP.

Hope to help

Giuseppe
