these two message blocks are repeated all over the time. we are using one wlc-4404, two acs and about 80 1131ag lwapp access points at the moment.

firmware release is 4.1.185. the 7921's are using the firmware 1.0.4. we are using eap-fast for the 7921 phones.


best regards,

joerg


edit from my side:

the message: "Could not Process 802.11 MAC mgmt Data. Invalid toDs/fromDs bit set - packet ignored." appears every time when there is an incoming call for a pick up group, which is configured on the 7921's phones.

Messgaes in Block 2 is due to IAPP. IAPP is the protocol used for AP to AP communication and also by CCX clients for management communication. There is a known issue with Intel clients were they send the incorrect length in the IAPP packets they send to the controller. Upgrade the client software.
