OL-31336-01
Caveats
Workaround: Use the controller CLI to edit the guest user’s parameters.
• CSCsq22518—CCKM clients using WPA2 reauthenticate when moving between hybrid-REAP
access points.
Workaround: None.
• CSCsq22827—The access point name sometimes disappears from the controller GUI and CLI.
Workaround: None.
• CSCsq23594—When a CCXv5 request is manually sent to a CCXv5 client, an emergency log
message is written to the log and sent to any configured syslog servers.
Workaround: None.
• CSCsq23806—Guest tunneling might not work if the WLAN on the foreign controller is created
using the controller GUI and the WLAN on the anchor controller is created using WCS.
Workaround: Reboot the anchor controller or use the same method (either the controller GUI or
WCS) to create the WLAN on both the anchor and foreign controllers.
• CSCsq25129—A controller software upgrade might fail with a Nessus scan running.
Workaround: None.
• CSCsq26051—When a Cisco terminal server connects to the controller but the user is not logged in
through the console, the controller might hang after a reboot.
Workaround: None.
• CSCsq29243—When you configure the 802.11h channel switch mode, you should be able to enter
only 0 or 1, but you can enter any value.
Workaround: None.
• CSCsq30821—When a WLAN is configured on two controllers using web authentication and the
WLAN is on a different VLAN on each controller, web authentication can be bypassed if a client
roams from one controller to another controller and then back to the first controller.
Workaround: Make sure that any WLAN spanning two controllers using web authentication is on
the same VLAN on both controllers.
• CSCsq31622— An SNMP error occurs when you enable voice and video parameters on the
controller using WCS.
Workaround: Disable all WMM-enabled WLANs and enable voice and video parameters.
• CSCsq32038—The config interface CLI command allows up to 31 characters to be entered for the
interface name. It should allow up to 32 characters.
Workaround: None.
• CSCsq34262—A traceback might occur if you include three controllers in the same mobility group
and enable a dynamic interface on all of them.
Workaround: Reset the controller.
• CSCsq35402—After you upgrade the controller to software release 4.2.125.0, the following error
message appears on the console of the Cisco WiSM controllers: “Mon May 19 12:56:44 2008:
dtlARPProtoRecv: Invalid ARP packet!”
Workaround: None.
• CSCsq35574—The Authorityid and the server key do not accept a value of 17 or greater.
Workaround: None.
