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 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
Refer to
for information on configuring the WiSM’s ports and interfaces.
Configuring the Supervisor
Log into the switch or router 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
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
module_number
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 is carried on the trunk between the WiSM controller and
the supervisor.
Note
Services might be temporarily interrupted (for
approximately two pings) after you enter this command.
Step 7
wism module
module_number
controller
{
1 | 2
}
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.
