I'm in the process of redeploying a 4400-series WLAN controller (v.126.96.36.199). I want to remove the mobility group members, however I get the following error whenever I attempt to do so:
"Cannot delete mobility group member. Any anchor should be deleted from WLAN first."
The thing is, there are no WLANs, hence no anchors. I tried recreating WLANs and adding the mobility members as anchors, deleting the anchors, then trying to delete the mobility group members, yet I still get the aformentioned error message. I attempted this via GUI and CLI. I also tried rebooting the controller and that didn't help either.
I'm out of ideas, so I'm hoping that someone has seen this before and knows a workaround. Let me know if you have any suggestions, other than clearing the config on the controller. Thanks.
In an ideal world, yes, I would typically blast the config and start from scratch.
However, when you are employed by a global corporation and the controller you are working on happens to be located on another continent, restoring the controller to factory defaults is simply not an option.
I know it's old, but I found the answer because I had the same problem.
I had to cheat by using the CLI though. ;)
"show mobility anchor" in the CLI will list your mobility groups and anchors. That tells you the WLAN ID that has this IP address as an anchor, very helpful if you have dozens of WLANs. eg:
(WiSM-slot1-1) >show mobility anchor
Mobility Anchor Export List
WLAN ID IP Address Status ------- --------------- ------ 5 188.8.131.52 Control and Data Path Down 5 184.108.40.206 Up
GLAN ID IP Address Status ------- --------------- ------
So now I go into my WiSM GUI and I go to WLANs, hover on the blue arrow next to WLAN ID 5, and click on "Mobility Anchors."
I hover on the blue arrow next to 220.127.116.11 and click "Remove." There's a dialog box about temporarily disrupting users on that WLAN, so you may have to do this during a maintenance window if it's in production. Need to do this for each WLAN.
Then you can go back to the Controller tab, Mobility Management, Mobility Groups, and remove 18.104.22.168 successfully.
