Configuring the Supervis or 720 to Support t he WiSM
General WiSM Guidelines
Keep these general guidelines in mind when you add a WiSM to your network:
The switch ports leading to the controller service port are automatically configured and cannot be
manually configured.
The switch ports leading to the controller data ports should be configured as edge ports to avoid
sending unnecessary BPDUs.
The switch 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 f or carrying data
traffic to and from the controllers.
The WiSM controllers support Layer 3 LWAPP mode, but they do not support Layer 2 LWAPP
mode.
Note Refer to Chapter 3 for information on configuring the WiSM’s ports and interfaces.
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:
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface vlan Create a VLAN to communicate with the data ports on the WiSM
and enter interface config mode.
Step3 ip address ip-address gateway Assign an IP address and gateway to the VLAN.
Step4 ip helper-address ip-address Assign a helper address to the VLAN.
Step5 end Return to global config mode.
Step6 interface port-channel 1 Configure a port-channel to bundle the automatically created
Gigabit interfaces 1-4 into an etherchannel.
a. switchport trunk
encapsulation dot1q
Configure the previously created port-channel interfaces as trunk
ports. For the native VLAN on the ports, configure the VLAN that
you created for communicating with the WiSM data ports.
b. switchport trunk native vlan
vlan
c. switchport mode trunk
d. end Return to global config mode.
