Примечания к выпуску для Cisco Cisco 2106 Wireless LAN Controller

parameters on the Global Configuration page and click Apply, the controller does not clear the 
parameters.

CSCsv34136—When an RFC3576 message arrives, the controller enforces a source port check by 
searching for the server using the IP address and source port in the RFC3576 message rather than 
searching the configured RADIUS servers list using the same Find Server function as for any other 
RADIUS message.

CSCsv34605—An access point using the Rogue Location Detection Protocol (RLDP) does not 
obtain a DHCP address if the DHCP server is on an autonomous access point. As a result, RLDP 
does not detect if a rogue access point is on the wire.

CSCsx29956—A 4400 series controller might reboot when it is configured to operate with an LDAP 
server because of a software failure of the LDAP DB Task 2 task.
