Virtual Interface Configuration

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:

  1. Select Configuration → Devices → System Profile from the web UI.
    A list of device profiles is displayed in the right-hand UI. This list contains default and user-defined profiles.
  2. Select a profile from those listed on the screen.
    The profile's configuration menu is displayed.
  3. Expand the Interface menu and select Virtual Interfaces.
    Click to expand in new window
    Profile Interface - Virtual Interfaces screen
  4. Review the following parameters unique to each virtual interface configuration:
    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.
