Creating a network interface bond (NIC bond) on the Velocity physical appliance

Velocity Help

You can bond multiple physical network ports across the available network cards (NICs) on the appliance. Bonding physical network ports (also known as link aggregation) allows for increased throughput and greater redundancy should one of ports fail on the appliance.

If only one port is configured, bonding is not available. If multiple ports are configured on the appliance, they are identified automatically.

Use the following guidelines when creating a network interface bond:

  • At least one of the ports that you want to bond must be plugged.

  • Only ports of the same type and speed can be bonded together (such as 1GB or 10GB, and fibre or copper).

  • None of the selected ports should have VLANs tagged to them.

  • None of the selected ports can be part of another bond.

  • All of the ports that participate in a bond should be connected to the same switch. In addition, no additional port configuration is done at the switch.

  • You should only configure network interface bonds using the Velocity shell menu.

    Network interface bonds that are configured with unsupported tools can appear as Disabled when you use other networking features, such as WAN optimization.

To create a network interface bond

  1. Log on to the Velocity shell menu.

  2. From the Main_Menu > Network view, type the following command:

    LinkAggregation Create <Slaves> [[BondingMode]]

    Where <Slaves> is a comma-separated list of two or more port names, and [[BondingMode]] is the desired mode for the bond. For example:

    LinkAggregation Create eth1,eth2,eth3 balance-tlb

    The available bond modes are:

    • balance-alb (default)

    • balance-rr

    • active-backup

    • balance-xor

    • broadcast

    • 802.3ad

    • balance-tlb

    Some bond modes require additional configuration on the switch or the router. For more information about bond modes, refer to the following documentation:

    http://www.kernel.org/doc/Documentation/networking/bonding.txt

You do not have to assign an IP address to the bond. However, if one of the ports already has an IP address that is assigned to it, the bond inherits that IP address.

If more than one port has an IP address that is assigned to it when you try to create the bond, the operation fails.
