Release Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for Release 4.2.61.0
OL-31336-01
Caveats
•
CSCsi78368—The client packet dot1p check, which performs the client’s tos-to-DSCP translation,
is not supported in controller software release 4.2 for packets from wireless clients to the network.
The priority is always mapped to 0 (null). This problem occurs when you configure the “qos profile”
for platinum, gold, silver, or bronze and the “wired qos protocol” for type = 802.1p and tag = N.
This issue affects the priority field in the dot1p vlan header tag for the 4.2 release, so clients on
VLANs are affected.

CSCsi81630—The controller might reboot repeatedly around 5 minutes after startup. This condition
