You can basically bond 2 interfaces so that you have a backup interface in case the primary interface goes down (switchport goes down for example). This does not load balance connections on 2 interfaces.

server has the following NIC redundancy settings that you can choose from:

  • None—The Ethernet ports operate independently and do not fail over if there is a problem. This setting can be used only with the Dedicated NIC mode.

  • Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.

  • Active-active—All Ethernet ports are utilized simultaneously. Shared LOM EXT mode can have only this NIC redundancy setting. Shared LOM and Cisco Card modes can have both Active-standby and Active-active settings.

    The active/active setting uses Mode 5 or Balance-TLB (adaptive transmit load balancing). This is channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.
