Chapter 4 Configuring Controller Settings
Configuring the Supervisor 720 to Support the 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 for 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 | |
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 | Assign an IP address and gateway to the VLAN. | ||
Step 4 |
|
| |
ip | Assign a helper address to the VLAN. | ||
Step 5 |
|

end |
| Return to global config mode. | |
Step 6 |
|

interface | Configure a | ||
|
|
| Gigabit interfaces |
|
|
|
|
| a. | switchport trunk | Configure the previously created |
|
| encapsulation dot1q | ports. For the native VLAN on the ports, configure the VLAN that |
|
|
| you created for communicating with the WiSM data ports. |
|
|
| |
