Chapter 4 Configuring Controller Settings
Using the Wireless LAN Controller Network Module
Note The WiSM is supported on Cisco 7600 series routers running only Cisco IOS Release 12.2(18)SXF5.
General WiSM Guidelines
Follow these guidelines when you add a WiSM to your network:
The switch or router ports leading to the controller service port are automatically configured and
cannot be manually configured.
The switch or router ports leading to the controller data ports should be configured as edge ports to
avoid sending unnecessary BPDUs.
The switch or router ports leading to the controller data ports should not be configured with any
additional settings (such as port channel or SPAN destination) other than settings necessary for
carrying data traffic to and from the controllers.
Note See Chapter 3, “Configuring Ports and Interfaces, for information on configuring the WiSM’s ports and
interfaces.
Configuring the Supervisor
Note You must log into the switch or router CLI and begin in privileged EXEC mode.
To configure the supervisor to support the WiSM, follow these steps:
Note The commands used for communication between the Cisco WiSM, the Supervisor 720, and the 4404
controllers are documented in Configuring a Cisco Wireless Services Module and Wireless Control

Using the Wireless LAN Controller Network Module
Follow these guidelines when using a wireless LAN controller network module (CNM) installed in a
Cisco Integrated Services Router:
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.
