Примечания к выпуску для Cisco Cisco 2106 Wireless LAN Controller

This section describes important information about the controllers and access points.

When clients use the controller’s internal DHCP server, IP addresses are not preserved across reboots. 
As a result, multiple clients can be assigned the same IP address. To resolve any IP address conflicts, 
clients must release their existing IP address and request a new one.

Several messages might flood the message logs when the controller boots up. These messages appear 
because of a failure to read or delete several different configuration files. These are low-severity 
messages that can safely be ignored. They do not affect controller functionality. These are some 
examples:

Mar 18 16:05:56.753 osapi_file.c:274 OSAPI-5-FILE_DEL_FAILED: Failed to delete the file : 

sshpmInitParms.cfg. file removal failed.

-Process: Name:fp_main_task, Id:11ca7618

Mar 18 16:05:56.753 osapi_file.c:274 OSAPI-5-FILE_DEL_FAILED: Failed to delete the file : 

bcastInitParms.cfg. file removal failed.

-Process: Name:fp_main_task, Id:11ca7618

The controller supports web authentication redirects only to HTTP (HTTP over TCP) servers. It does not 
support web authentication redirects to HTTPS (HTTP over SSL) servers.

At this time, the controller software does not provide full support of the IPv6 and DHCPv6 stack. If you 
enable WLAN override with IPv6, the clients move to the correct VLAN but do not obtain an IPv6 
address using DHCP (CSCsv79914). However, static IPv6 addresses operate correctly with the WLAN 
override feature.

The config, show, and debug location plm path loss measurement location commands are not supported 
in controller software release 5.1.163.0, although they appear in the CLI code.

Cisco 1250 series access points are not supported for use with the Cisco 7920 IP phone. They can, 
however, be used with the Cisco 7921 and 7925 IP phones.
