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.

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
