Override VLAN Configuration

About this task

A virtual interface is required for layer 3 (IP) access to a controller or service platform or provide to layer 3 service on a VLAN. The virtual interface defines which IP address is associated with each VLAN ID the controller or service platform is connected to. A virtual interface is created for the default VLAN (VLAN 1) to enable remote administration. A virtual interface is also used to map VLANs to IP address ranges. This mapping determines the destination for routing.

To review existing virtual interface configurations and create a new virtual interface configuration, modify (override) an existing configuration or delete an existing configuration:

Procedure

Go to Configuration → Devices.
The Device Configuration screen displays. This screen lists access points, controllers and service platforms within the managed network.
Select a target device by double-clicking on the device name.

Note
You can also select the target device from the device browser in the lower, left-hand, side of the UI.

The selected device's configuration menu displays.
Go to Profile Overrides → Interface → Virtual Interfaces.

Note
A blue override icon (to the left of a parameter) defines the parameter as having an override applied. To remove overrides from a device, go to the Basic Configuration screen for the device and select Clear Overrides.

Profile Overrides - Virtual Interfaces Screen

Review the following parameters, unique to each virtual interface configuration, to determine whether a parameter override is warranted:


Name	The name of each listed virtual interface assigned when it was created. The name is between 1 - 4094, and cannot be modified as part of a virtual interface edit.
Type	The type of virtual interface for each listed interface.
Description	The description defined for the virtual interface, either when it was created or when it was edited.
Admin Status	A green check mark means the listed virtual interface configuration is active and enabled with its supported profile. A red “X” means the virtual interface is currently shut down. The interface status can be modified when a new virtual interface is created or an existing one modified.
VLAN	The numerical VLAN ID associated with each listed interface.
IP Address	Whether DHCP was used to obtain the primary IP address used by the virtual interface configuration.

After reviewing the configurations of existing virtual interfaces, determine whether a new interface needs to be created, an existing virtual interface needs to be edited (overridden), or an existing virtual interface needs to be deleted.
