    ItemDescription

    Data Interface

    Choose an option from the Data Interface drop-down list: Primary or Secondary.
    Designate either the Primary or Secondary interface as the active interface for data. You can assign the same interface link type for both data and voice or choose different interface types for load balancing data and voice traffic across multiple links. By default, the data and voice interfaces are assigned to the Primary link.

    Voice InterfaceChoose an option from the Voice Interface drop-down list: Primary or Secondary.
    Designate either the Primary or Secondary interface as the active interface for voice. You can assign the same interface link type for both data and voice or choose different interface types for load balancing data and voice traffic across multiple links. By default, the data and voice interfaces are assigned to the Primary link.

    Voice and Data Interface Lists

    Use the drop-down arrows to select the priority of available voice and data VLAN or non-VLAN interfaces. Click the up and down arrows to change the priority.

    • Status displays the current status of the interface:
      • Red: Unavailable.
      • Green: Available and active.
      • White: Available but inactive.
    • Link displays Primary and Secondary interface names.
    • VLAN displays the VLAN ID of the VLAN. If the VLAN is not configured, this field is blank.
    • IPv4 displays the IPv4 address of the interface.
    • IPv6 displays the IPv6 address of the interface.
    • Action changes the priority of each interface.
    Enable WAN Link RedundancySelect the check-box to enable or disable WAN link redundancy.

    Enable Revertive Mode

    Select the check-box to activate automatic switchback between Primary and Secondary interfaces. Deselect the box to disable. 

    Note

    In a revertive mode, the VLAN switches over to the high priority VLAN as soon as it becomes reachable and used for the WAN side connection.

    (Optional) Non-revertive switchover for the Primary interface. If the Secondary interface is functioning as the active interface and the Primary interface becomes available, the system continues to use the Secondary interface and no switchover occurs.

    Note

    In a non-revertive mode, if the current VLAN fails, the VLAN switches over to the highest priority VLAN that it can reach.

    Note

    Non-VLAN interfaces provide voice+data services. You cannot change their configurations in the Purpose field. (Refer to Configuring Multiple VLANs on the WAN Interface for field details). 

    Enable Dual WAN Ports

    Check this box to enable the use of the second WAN port. Refer to Configure WAN Failover Advanced Settings for configuring the second WAN interface.

    Switchover Interfaces

    Select an option from the Switchover Interfaces drop-down list to configure the interfaces for WLR:

    • Data+Voice
    • Data Only
    • Voice Only

    The default option is Data+Voice.

    Selecting the Data Only option allows data interface to switch over between the Primary and Secondary links, while the voice interface is fixed to its configured link.

    WAN Link Details

    Displays Primary and Secondary interface names and IP addresses:

    Primary Link Name
    Primary Link IPv4 Address
    Primary Link IPv6 Address
    Secondary Link Name
    Secondary Link IPv4 Address
    Secondary Link IPv6 Address

    Manual Switchover

    Switches voice and data services from their currently active interfaces to their inactive interfaces when revertive mode is disabled. This results in a network restart.

    Note: Manual Switchover is only available when the system is configured in non-revertive mode. If the Secondary interface is functioning as the active interface, and the Primary interface becomes available, the system automatically switches back to the Primary interface as the active interface (making the Secondary interface inactive).

    For more information about restarting the network, choose Network > Network Restart and refer to Initiating Network Restart. 

    WAN Failover Status

    Shows currently active voice and data information and describes whether the Primary and Secondary interfaces are up or down. The status is only visible when the WAN failover feature is enabled on the system. The status is displayed on the basis of link detection via IOCTL and the optional ping link detection mechanism:

    Current Active Data Interface—Primary or Secondary
    Current Active Voice Interface—Primary or Secondary
    Primary Link Status—Available or Unavailable
    Secondary Link Status—Available or Unavailable
