  • This feature is not supported on vNIOS Grid members for Riverbed.
  • NIC failover for LAN1 and LAN2 is not supported on AWS members.

    The LAN2 port is a 10/100/1000Base-T Ethernet connector on the front panel of the TE-810, TE-820, TE-1410, TE-1420, TE-2210, TE-2220, and IB-4010 appliances. By default, the LAN2 port is disabled and the appliance uses the LAN1 port (and HA port when deployed in an HA pair). Before you can enable and configure the LAN2 port on a Grid member, you must first configure the member and join it to the Grid. You must also have read/write permission to the Grid member on which you want to enable the port. When you enable the LAN2 port and SNMP, the appliance sends traps from this port for LAN2 related events.

    You can configure the LAN2 or LAN2 (VLAN) port to provide redundancy and additional fault tolerance in your network. Port redundancy is transparently supported for both IPv4 and IPv6. When you enable port redundancy, the LAN1 or LAN1 (VLAN) and LAN2 or LAN2 (VLAN) ports are grouped into one logical interface. They share one IP address and appear as one interface to the network. Then, if a link to one of the ports fails or is disabled, the appliance fails over to the other port, avoiding a service disruption.
    You can connect the LAN1 or LAN1 (VLAN) and LAN2 or LAN2 (VLAN) ports to the same switch or to different switches, but the VLAN configuration between LAN1 and LAN2 must match. One port is active and the other port is idle at all times. In case of failure in the LAN1 or LAN1 (VLAN) port, the LAN2 or LAN2 (VLAN) port becomes active and once the LAN1 or LAN1 (VLAN) port is active again, the LAN2 or LAN2 (VLAN) port becomes passive if the Use LAN1 when available option is enabled. For more information, see Enabling Port Redundancy.

    Note
    titleNote
    • When configuring port redundancy, the speed of the interfaces is not taken into consideration when selecting the active interface.
    • All L2 packets are dropped on the bond0 passive interface if you enable port redundancy on the node. This is applicable only for PT-1405, PT-2205, PT-2205-10GE, IB-4030, and IB-4030-10GE appliances.
