Using the Wireless LAN Controller Network Module

Keep these guidelines in mind when using a wireless LAN controller network module (CNM) installed
in a Cisco Integrated Services Router:
OL-17037-01
The CNM does not support IPSec. To use IPSec with the CNM, configure IPSec on the router in
which the CNM is installed. Click this link to browse to IPSec configuration instructions for routers:

The CNM does not have a battery and cannot save a time setting. It must receive a time setting from
an external NTP server when it powers up. When you install the module, the configuration wizard
prompts you for NTP server information.
To access the CNM bootloader, Cisco recommends that you reset the CNM from the router. If you
reset the CNM from a CNM user interface, the router might reset the CNM while you are using the
bootloader.
When you reset the CNM from a CNM interface, you have 17 minutes to use the bootloader before
the router automatically resets the CNM. The CNM bootloader does not run the Router Blade
Configuration Protocol (RBCP), so the RBCP heartbeat running on the router times out after 17
minutes, triggering a reset of the CNM.
If you reset the CNM from the router, the router stops the RBCP heartbeat exchange and does not
restart it until the CNM boots up. To reset the CNM from the router, enter one of these commands
on the router CLI:
service-module wlan-controller 1/0 reset (for Fast Ethernet CNM versions)
service-module integrated-service-engine 1/0 reset (for Gigabit Ethernet CNM versions)
Gigabit Ethernet versions of the Controller Network Module are supported on Cisco 28/37/38xx
Series Integrated Services Routers running Cisco IOS Release 12.4(11)T2 or later.
