dynamic interface port assignment

Unanswered Question
Jan 15th, 2009

Good Day,

I am setting up a 4402 (50 ap license ver 5.0) that will manage about 40 aps. Following the Cisco docs, I have created two ap manager intefaces for load balancing. Each physical port is attached to one of two Cat 6509s (no lag).

Our network ultimately connects to a router (over which I have no control) with six 100 mps ports each representing a subnet/vlan. So my intent is to create six dynamic interfaces each coresponding to a vlan for load balancing and bandwidth optimization.

My question regards assinging each dynamic interface to a physical port. Simple logic would have me assinging 3 interfaces to port #1 and three to port #2, then assigning a proportionate number of aps to each interface.

Is it that simple, or are there other considerations.

Thanks

I have this problem too.

You're correct. Creating a dynamic interface for each VLAN is exactly what you need to do. This will load-balance the traffic from the multiple VLANs across your links.

I would highly recommend that you consider LAGging the two uplinks. It provides better load-balancing and better redundancy. Since you're connecting to a 6509, you can LAG between two blades for redundancy purposes.

Whether you LAG or not is completely up to you, of course. But you seem to be good to go if you want to leave them unLAGged.
