Hi, has anyone seen this problem, or is this a bug:
Auto-anchor is configured for guest mobility and has been working fine on a number of 4400 controllers in a mobility group. Guests get auto-anchored to a 4400 with access to the guest DMZ
we have now introduced both 2006 and 2106 controllers into the mobility group, however clients are net getting DHCP when coming through these controllers.
debugs show an apparent disinterest on the part of the 4400 to respond to mobility anchor requests from the 2x06, and mobility statistics report increase in 'ignored' requests
mobility debug on 4400 for unsuccessful request from 2106:

Guest tunneling provides additional security for guest-user access to the corporate wireless network. Refer URL

Thanks for that, however: the configuration works fine on the 4400, but appears not to work on the 2x06

Hello
I don?t think the 20x6 controller support that.
http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn40216.html#wp44028
These software features are not supported on 2000 and 2100 series controllers:
?Termination of guest controller tunnels (origination of guest controller tunnels is supported)

Hi
Sure the 2106 doesn't support that. We are terminating the Anchor on a 4400.

Hi Graeme
One requirement for the Mobility Group Auto Anchor feature is that ALL controllers must run the same version of code to work efficiently.
My suggestion here is to check the code versions on the 2006 and 2106 controllers and ensure that the 4400 is added as a Mobility peer which seems to be from your debug.
I have added various 2006 controllers to a setup like this and all work fine.

Thanks Steven
All were running the same code.
I just wanted to see if anyone was running the same setup with it working - which you are so that helps a lot!
which ver are you running?
kind regards

I am running version 4.1.171.0 on the WLAN Controllers and version 4.1.83.0 on the Wireless Control System.

thanks

would it possible to send a config of the anchor 4400 and one 2106, security stuff removed obviously
