Configuring the Supervisor 720 to Support the WiSM

Configuring the Supervisor 720 to Support the WiSM
When you install a WiSM in a Cisco Catalyst 6500 switch, you must configure the Supervisor 720 to
support the WiSM. When the supervisor detects the WiSM, the supervisor creates 10 GigabitEthernet
interfaces, ranging from Gigslot/1 to Gigslot/8. For example, if the WiSM is in slot 9, the supervisor
creates interfaces Gig9/1 through Gig9/8. The first eight GigabitEthernet interfaces must be organized
into two etherchannel bundles of four interfaces each. The remaining two GigabitEthernet interfaces are
used as service-port interfaces, one for each controller on the WiSM. You must manually create VLANs
to communicate with the ports on the WiSM.
The WiSM is also supported on Cisco 7600 Series Routers running only Cisco IOS Release

The statistics are shown in 90-second intervals. The timestamp field shows the specific
Note
interval when the statistics were collected.
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.
