Cisco Cisco 2106 Wireless LAN Controller

This section lists 

 and 

 for Cisco controllers and lightweight access points 

in software release 4.2.99.0.

The caveats listed below are open in controller software release 4.2.99.0.

CSCsb20269—On the Cisco WiSM, when the service VLAN is configured as one of the VLANs on 
a data port, it does not operate correctly.

Workaround: Do not configure the service VLAN as one of the VLANs on a data port.

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.

CSCsb85113—When users download the code image to the Cisco WiSM using the CLI, associated 
access points are sometimes disconnected.

Workaround: Download new code images to the WiSM at times when there are no clients to be 
affected.

CSCsd52483—When you make changes in the boot loader of a 2006 controller or a Controller 
Network Module, the bootup process may halt, and the controller may stop responding. 

Workaround: None at this time. The controller must be returned for repair through the RMA process.

CSCsd54171—After the controller configuration is modified, the changes may not take effect or 
function properly. 

Workaround: Save the controller configuration to a TFTP server or WCS; then reset the controller 
to restore the default configuration. After completing the setup wizard, reload the saved 
configuration from the TFTP server or WCS.

CSCsg12879—When you attempt to disable power-over-Ethernet (PoE) through the controller GUI, 
the following error message appears: “Error is setting Power Over Ethernet.”

Workaround: None at this time.

CSCsg36747—The Clear Counters button on the Controller Statistics page does not clear the 
controller’s counters.

Workaround: None at this time.

CSCsg44650—Cisco Discovery Protocol (CDP) does not operate correctly when a 2106 controller 
is connected to a 3750 switch. The controller sees the 3750 chassis as a CDP neighbor, but the 3750 
does not recognize the 2106.

Workaround: None at this time.

CSCsg55649—Internet Group Management Protocol (IGMP) V3 join reports sent by the client upon 
starting a multicast application may be duplicated to one of the controller ports in the link 
aggregation (LAG) bundle.

Workaround: None at this time.

CSCsg65482—Controllers sometimes drop multicast packets in unicast or multicast mode.

Workaround: None at this time.
