Using the Wireless LAN Controller Network Module
Configuring the Supervisor
Log into the switch CLI and, beginning in Privileged Exec mode, follow these steps to configure the
supervisor to support the WiSM:
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:
•
The controller network module 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 controller network module does not have a battery and cannot save a time setting. It must receive
a time setting from an NTP server when it powers up. When you install the module the configuration
wizard prompts you for NTP server information.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface
vlan
Create a VLAN to communicate with the data ports on the WiSM
and enter interface config mode.
Step 3
ip address
ip-address gateway
Assign an IP address and gateway to the VLAN.
Step 4
ip helper-address
ip-address
Assign a helper address to the VLAN.
Step 5
end
Return to global config mode.
Step 6
wism module

controller
{
1
|
2
}
allowed-vlan
vlan_number
Create Gigabit port-channel interfaces automatically for the
specified WiSM controller and configure the port-channel
interfaces as trunk ports. Also, specify the VLAN you created
earlier as the allowed VLAN on the port-channel trunk. VLAN
traffic will be carried on the trunk between the WiSM controller
and the supervisor.
Step 7

native-vlan
vlan_number
For the native VLAN on the ports, specify the VLAN that you
created earlier to communicate with the WiSM data ports.
Step 8
interface
vlan
Create a VLAN to communicate with the service ports on the
WiSM.
Step 9
ip address
ip-address gateway
Assign an IP address and gateway to the VLAN.
Step 10
end
Return to global config mode.
Step 11
wism service-vlan
vlan
Configure the VLAN that you created in steps 8 through 10 to
communicate with the WiSM service ports.
Step 12
end
Return to global config mode.
Step 13
show wism status
Verify that the WiSM is operational.
