configure terminal
Step 2
interface vlan
Step 3
ip address ip-address gateway
Step 4 ip helper-address ip-address
Step 5 end
Step 6

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.
Chapter 3 for information on configuring the WiSM's ports and interfaces.
Chapter 4 Configuring Controller SettingsWireless Device Access
Purpose
Enter global configuration mode.
Create a VLAN to communicate with the data ports on the WiSM
and enter interface config mode.
Assign an IP address and gateway to the VLAN.
Assign a helper address to the VLAN.
Return to global config mode.
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 is carried on the trunk between the WiSM controller and
the supervisor.
Services might be temporarily interrupted (for
Note
approximately two pings) after you enter this command.
For the native VLAN on the ports, specify the VLAN that you
created earlier to communicate with the WiSM data ports.
Create a VLAN to communicate with the service ports on the
WiSM.
Assign an IP address and gateway to the VLAN.
Return to global config mode.
Configure the VLAN that you created in steps 8 through 10 to
communicate with the WiSM service ports.
