Can't delete WLAN, missing anchor config...

[Rob Simkins]

Using WLC v7.6.100.0

(Cisco Controller) >config wlan delete <n>

This WLAN is used in AP groups.
Are you sure you want to continue? (y/n) y

Anchors configured on WLAN - unable to delete WLAN entry.

There are no anchors configured on the WLAN... I think this is seen when an IP address changes in the mobility group, but the anchor for a WLAN isn't removed prior to the change.  This is an old bug from 4.2

Anyone got a workaround other than resetting the WLC?  That would be very annoying...

Hi Rob,

Did you try the workaround given in the bugID you provided. ? It may work if this is a similar case.

"Add an anchor to this wlan and then delete the same, the wlan can be delete after this."

Hi Rasika,

Yes I tried that .

One thing to note is that when you add the problem anchor it no longer appears on the list of selectable anchors but it doesn't appear above in the configured anchors...

I then tried removing all WLAN anchor configs, then changing the mobility group entry for the anchor WLC to the previous (original) IP entry, then adding and removing that.

So I assume that there is hidden WLAN config mapping anchor wlc by MAC to IP...  If there is a mobility group change this config goes into limbo.... It's still there but is removed from GUI and console running config somehow

:S

So, was there any solution to this? I'm having the same issue right now on a 5508 7.6.130.0. The WLAN has no anchors associated to it and I still can't delete it. I tried to add an anchor and delete it again to no avail.

Have to tried to backup the config and edit it and then you can do a restore. The WLC will reboot though when restoring the config. -Scott

Sound like a plan. I'll try that. Thanks
