Re: How was connected 4404 controller to the 6509?
You should configure channel-group 11 to "on" not desirable.
Note When a 4404 controller or WiSM controller module LAG port is connected to a Catalyst 3750G or 6500 channel group employing load balancing, note the following:
â¢LAG requires the etherchannel to be configured for the "on" mode on both the controller and the Catalyst switch.
â¢Once the etherchannel is configured as "on," at both ends of the link, it does not matter if the Catalyst switch is configured with either Link Aggregation Control Protocol (LACP) or Cisco proprietary Port Aggregation Protocol (PAgP) because no channel negotiation is done between the controller and the switch. Additionally, LACP and PAgP are not supported on the controller.
