Caveats
This section lists Open Caveats and Resolved Caveats for Cisco controllers and lightweight access
points.
Open Caveats
These caveats are open in controller software release 4.2.176.0.
• CSCsb77595—When logging out from Telnet/SSH sessions, the session always prompts the user to
save changes, even when no changes have been made.
Workaround: Ignore the prompt and exit as usual.
• CSCsd54928—The CPU ACL is unable to block LWAPP packets that are destined for the IP address
of the dynamic interface.
Workaround: None.
• CSCsd84706—Containment information for ad-hoc rogue access points is not shown on the
controller GUI.
Workaround: Use the controller CLI.
• CSCsd95723—Some users might be confused when presented with the None and DHCP options for
configuring the service port interface in the initial controller setup wizard. These options are
available for a controller that has no configuration and the setup wizard is being used to configure it.
Workaround: Users can interpret the None option as Static and a logical alternative to DHCP.
• CSCse06202—When a controller’s IKE lifetime expires, a rekey is not offered.
Workaround: None.
• CSCse06206—The controller sends a DEL notification when the IKE lifetime expires, but it does
not send the notice to the client.
Workaround: None.
• CSCse87087—A controller with link aggregation (LAG) enabled fails Ethernet link redundancy.
This problem occurs when the controller uses an Ethernet copper gigabit interface converter (GBIC)
instead of a fiber GBIC and one of two Ethernet cables is pulled out of the GBIC.
Workaround: Clear the configuration on the controller. Then reconfigure the controller and perform
the redundancy test.
• CSCsg04831—There are not enough debugs to determine the packet flow in the controller for guest
access.
Workaround: Use a wireless sniffer trace.
• CSCsg48089—If you lose your controller password and have not backed up the configuration, the
recovery mechanism is to revert to the factory default settings.
Workaround: None.
