Hi


We have a mobility anchor to local eduroam hub, had this sicnce 2015.

They have just upgraded there AAA to ISE, all working, but there is an issue.

We have 5 cataylst WLCs conencting, we use these 2 vlan 621 & 622 in our corporate range and Eduroam Hub are now using 621 and 622 on there side in 

In our logs and theirs it show instead of the traffic going via the management, it trys to go via my local vlan on the WLC and in ISE.

There is no obviuse setting, never seen this before, now has gone to a 3rd party support, just wonderting if any one has seen this before?

I'm just passing their traffic through

Unclear what the "weird things happening" means and no clear errors to troubleshoot which is probably why there have been no responses after more than 1 week.

Suggest calling TAC so they can help if your 3rd party support cannot.

found the issue, and wasn't from TAC, becouse using Dynamic Vlan Assignement, the Radius server on the Eduroam side was doign a second lookup on our WLC and found that there was asame vlan being used, so only way to stop this is for 1 side to remove the vlan or stop using the anchor.
