CAPWAP-3-DISC_AP_MGR_ERR1 errors since upgrade to 8.0.110.0

[Gerald Vogt]

I have upgraded a 2504 controller to 8.0.110.0. Since then I see this error message every two minutes:

wlc: *spamApTask7: Feb 17 12:07:23.854: #CAPWAP-3-DISC_AP_MGR_ERR1: capwap_ac_sm.c:2008 The system is unable to process Primary discovery request from AP [mac-address] on interface (1), VLAN (10), could not get IPv6 AP manager

The controller does not have IPv6 address configured (i.e. it's still ::/128).

The error only appears for the two 1602i in the network, not for the 1131ag.

All access points are connected to the controller and operate normally.

How do I get rid of these errors?

Thanks,

Gerald

v8.1 isn't out yet as it is still in beta:)  have you disabled IPv6 on the controller?

Global IPv6 config is enabled as I need IPv6 and as far as I understand clients won't be able to use IPv6 otherwise.

I haven't found a way to disable IPv6 for discovery...
