Mobility groups and MAC filtering

f00f1ter · ‎07-23-2009

We have a 4402 controller and we are doing MAC filtering. We have reached the default number of MAC addresses, 512. It has been recommended that we add an additional controller instead of increasing this past the default. Three questions:

1. Is there an increased (enough to impact performance) load placed on the WLC if the limit of MACs is increased, say to the max of 2048?

2. If we add an additional controller, configured in a mobility group, how do we configure the MAC filter to load balance? Or do we have to configure the same MAC table on both controllers? Which leads to....

3. Is there a benefit to adding another controller as far as MAC filtering is concerned?

Why not deploy Cisco ACS or Microsoft IAS and do AAA MAC filtering instead of configuring local MAC database?

That is not possible at this time. Do you have any info regarding the questions above? Any suggestions would be appreciated.

As it stands, you would need to manually replicate internal mac filtering database between two controllers, so you're not gaining much with the second controller. As regards to increasing database size and what effects it will have, I don't have an educated answer for you, sorry.
