Cisco Cisco 2106 Wireless LAN Controller Release Notes

The following enhanced distributed channel access (EDCA) CLI command appears in controller 
software release 6.0.182.0, but this command is not configurable and cannot be used:

config advanced {802.11a | 802.11b} edca-parameters custom profile_name {aifs | ecwmin | ecwmax 
| txop} value

The config band-select and config wlan band-select CLI commands appear in controller software 
release 6.0.182.0, but they are not supported and should not be used. Also, you can ignore the Band 
Select Stats information in the output of the show ap stats {802.11a | 802.11b} Cisco_AP command.

The config load-balancing denial and config wlan load-balance CLI commands appear in controller 
software release 6.0.182.0, but they are not supported and should not be used. Also, you can ignore the 
Denial Count information in the output of the show load-balancing command.

When controllers in the mobility list are running different software releases (such as 4.2, 5.0, 5.1, 5.2, 
and 6.0), Layer 2 or Layer 3 client roaming is not supported between them. It is supported only between 
controllers running the same release.

Guest tunneling works only between controllers running the same software release or between 
controllers running software release 4.2 and controllers running any later software release (for example, 
4.2 to 5.0, 4.2 to 5.1, 4.2 to 5.2, or 4.2 to 6.0). Guest tunneling does not work among controllers running 
other combinations of software.

Rogue Location Discovery Protocol (RLDP) is a controller feature that detects the presence of rogue 
access points that are connected to your wired network. In this software release, RLDP operates with 
these limitations:

RLDP detects rogue access points that are configured for open authentication. 

RLDP detects rogue access points that use a broadcast BSSID (that is, the access point broadcasts 
its SSID in beacons). 

RLDP detects only rogue access points that are on the same network. In other words, if an access 
list in the network prevents the sending of RLDP traffic from the rogue access point to the controller, 
RLDP does not work. 

RLDP does not work on 5-GHz dynamic frequency selection (DFS) channels. 

If the automatic RLDP attempt does not detect the rogue (due to a noisy RF environment, for 
example), the controller does not retry. However, you can initiate RLDP manually on a rogue at any 
time.

Also, in controller software release 6.0, the rogue containment packet transmission times have changed 
as follows:

For monitor mode, rogue containment deauthentication packets are still sent at 100-msec intervals.
