Примечания к выпуску для Cisco Cisco 4402 Wireless LAN Controller

CSCsi10071—The access point reboots after controller port recovery. If the access point is 
associating to the controller through the backup port, then when the primary port comes back, all of 
the access points reboot. At that time, the access point sends an “LWAPP CNTL ECHO_REQUEST” 
to the MAC address of the controller’s backup port, but there is no response. Then the access point 
reboots. This behavior only occurs when you change the LWAPP operation mode from Layer 3 (with 
controller port redundancy enabled) to Layer 2 and you change the management VLAN or IP to a 
different subnet after changing to Layer 2 mode.

Workaround: None at this time.

CSCsi21632—The access point sends out a deauthentication message (reason code: 0x0001) to 
FOMA clients at the interval set for WPA broadcast key rotation.

Workaround: None at this time.
