Define or override an Instance Index using the spinner control and set the Cost. The default
path cost depends on the user defined speed of the port.The cost helps determine the role of
the port in the MSTP network. The designated cost is the cost for a packet to travel from this
port to the root in the MSTP configuration. The slower the media, the higher the cost.
24. Select + Add Row as needed to include additional indexes.
25. Refer to the Spanning Tree Port Priority table.
Define or override an Instance Index using the spinner control and then set the Priority. The
lower the priority, the greater likelihood of the port becoming a designated port. Applying a
higher override value impacts the port’s likelihood of becoming a designated port.
26. Select + Add Row needed to include additional indexes.
27. Select OK to save the changes and overrides made to the Ethernet Port Spanning Tree
configuration. Select Reset to revert to the last saved configuration.
Virtual Interface Override Configuration
Profile Interface Override Configuration
A virtual interface is required for layer 3 (IP) access to the controller or service platform or to
provide layer 3 service on a VLAN. The virtual interface defines which IP address is associated with
each VLAN ID the controller is connected to. A virtual interface is created for the default VLAN
(VLAN 1) to enable remote controller administration. A virtual interface is also used to map VLANs
to IP address ranges. This mapping determines the destination for controller or service platform
routing.
To review existing virtual interface configurations and create a new virtual interface configuration,
modify (override) an existing configuration or delete an existing configuration:
1. Select the Configuration tab from the Web UI.
2. Select Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service
platforms or Access Points.
3. Select a target device (by double-clinking it) from amongst those displayed within the Device
Configuration screen.
