Only 24 controller in a mobility group?

Answered Question

I want to create a anchor controller that has a dot1q leg into our DMZ then make foreign contorllers for the rest of my company which would be 34 controllers in different geographic locations.  The problem I see is that I can only add 24 mobility members to the group to create the mobility peer as stated in this document.

What are people doing for mobility anchors with greater than 24 controllers?  I am running a mix of 6.0.182.0 and 4.2.112.0

Tim,


Yes you can only enter 24 static entries, so if you have redundant guest anchors, then you will have to get two more and split up the load between a pair of guest anchors.

Well... not all your WLC are in one area per say.... so each location can be one mobility group and your guest anchor would be in a seperate mobility group.  Mobility group helps a user roam from an ap in one controller to an ap in another.  You don't have to have every WLC on the same Mobility group nor RF Group.  Have one mobility group per location (one building, multiple buildings) where you can roam from one to another.

As of 5.1 or later you can add up to 72 controllers in a controller's mobility group list.  The mobility groups are still limited to 24 controllers but with the other controllers and mobility groups defined you can then have roaming between the mobility groups.

Also keep in mind that mobility between versions of controllers is only supported when both controllers are running a GD release:
