8.10(109.24)

Description (partial)

Symptom:
WLC sneed to send additional TLV in Capwap Discovery packet to handle 8.8.and 8.10  Click APs .

Conditions:
WLC sneed to send additional TLV in Capwap Discovery packet to handle 8.8.and 8.10  Click APs  to ignore the  expired MIC.

The present solution holds good for Click APs pre-8.8 release and for IOS APs ( all releases). The new payload is required in 8.8 and 8.10 for Click APs to ignore the expired MIC.

Problem.

If we changed the WLC time to beyond the date of MIC expire date, the Click APs are not able to join to WLC.
