Cisco Cisco 4402 Wireless LAN Controller

CSCse18855—RADIUS accounting cannot be disabled on an individual WLAN. Once a RADIUS 
accounting server is defined globally, WLANs fall back to the global RADIUS accounting server if 
no RADIUS accounting server is selected in the WLANs.

Workaround: Create a fictitious RADIUS accounting server and assign it to the WLAN for which 
RADIUS accounting is not required.

CSCse30452—After the secondary DHCP server provides an IP address to an access point, the 
access point shows “(tNetTask): arpresolve” and then reboots.

Workaround: None at this time.

CSCse30514—When an LWAPP-enabled AP1100 or AP1200 first connects to a controller, the 
secondary controller name on the All APs > Details page in the controller GUI is not blank. The 
output of the show ap config general command also shows that the secondary controller name is 
not blank.

Workaround: None at this time.

CSCse30696—The controller does not refresh the access point’s IP address correctly when the 
admin status for that access point is disabled.

Workaround: None at this time.

CSCse32656—The 4402 controller supports an enhanced security module (ESM) card only in slot 
1, not in slot 2. Slot 2 is reserved for 4404 controllers.

Workaround: Use slot 1, which is the slot closest to the power outlet, for an ESM card in the 4402 
controller.

CSCse40636—The foreign controller incorrectly forwards multicast traffic onto the auto-anchor 
WLAN.

Workaround: Configure the WLAN on the foreign controller to map to an invalid VLAN.

CSCse52143—IPSec authentication with certificates may not always operate properly.

Workaround: None at this time.

CSCse60689—The controller may reboot due to a failure with the sshpmAddIPv4IpsecRules 
software.

Workaround: None at this time.

CSCse72413—The controller may reboot due to a failure with the debugMaintask software.

Workaround: None at this time.

CSCse80636—Under heavy traffic conditions, the VPN module may reach capacity and fail to 
accept additional packets.

Workaround: None at this time.

CSCsf10167—The controller may reboot due to a failure with the pemReceiveTask software 
watchdog.

Workaround: None at this time.

CSCsf11862—Controllers sometimes reboot during a software upgrade.

Workaround: Download the software image twice. On the second try, the controller successfully 
loads the new image.

CSCsg10391—When you use the remote-debug enable command on the controller CLI to enable 
remote debugging on an access point, debugging stops when your CLI session times out.

Workaround: Open a new CLI session, disable remote debugging (enter remote-debug disable), and 
re-enable remote debugging.
