Cisco Cisco 2106 Wireless LAN Controller

These additional changes are applicable to controller software release 5.1.151.0:

The controller now supports traffic classification (TCLAS) coming from 7921 phones using 
firmware version 1.1.1. This feature ensures proper classification of voice streams to the 7921 
phones.

The default value for the RRM transmit power threshold has been changed from –65 dBm to –70 
dBm.

The config network arpunicast {enable | disable} command has been removed from the controller 
CLI, and the ARP Unicast Mode line has been removed from the output of the show network 
summary command (CSCsl72127).

The show run-config command now includes access point group information (CSCsi22092).

You can use these CLI commands to save debug messages to the controller buffer, the controller 
console, or an external syslog server (CSCsc33206):

config logging debug buffered {enable | disable}

config logging debug console {enable | disable}

config logging debug syslog {enable | disable}

You can use these CLI commands to enable or disable timestamps in log messages and debug 
messages (CSCsk66663):

config service timestamps log {datetime | disable}

config service timestamps debug {datetime | disable}

The LDAP SecureTLS mode feature, which is documented in previous releases, has been 
intentionally removed in controller software release 5.1.151.0 because it does not work properly 
(CSCso43490). On the controller GUI, the Server Mode field on the LDAP Servers pages has been 
removed. In the controller CLI, the secure option has been removed from the config ldap add index 
server_ip_address port# user_dn password base_dn {secure} command.

This section contains important information to keep in mind when installing controllers and access 
points.
