Creating a static multimode vif

You can use the vif create command to create a static multimode vif. If you do not specify the type of vif in the vif create command, a static multimode vif is created by default.

Before you begin

You must meet the following prerequisites to create a multimode vif:
  • Identify or install a switch that supports link aggregation over multiple port connections in your network, configured according to your switch vendor's instructions.
  • Decide on a case-sensitive name for the vif that meets the following criteria:
    • It must begin with a letter.
    • It must not contain a space.
    • It must not contain more than 15 characters.
    • It must not already be in use for a vif.
  • Decide on the interfaces that you want to select as part of the vif.
  • Configure all interfaces that are to be included in the vif to the down status, by using the ifconfig command.

About this task

You can improve throughput by creating a static multimode vif. With a multimode vif, all interfaces in the vif are active and share a single MAC address. This logical aggregation of interfaces provides higher throughput than a single-mode vif.

Steps

  1. To create the vif, enter the following command: vif create multi vif_name -b {rr|mac|ip|port} [interface_list]

    -b describes the load-balancing method.

    rr specifies round-robin load balancing.

    mac specifies MAC address load balancing.

    Note: Do not select the MAC address load-balancing method when creating vifs on a storage system that connects directly to a router. In such a setup, for every outgoing IP frame, the destination MAC address is the MAC address of the router. As a result, only one interface of the vif is used.

    ip indicates IP address load balancing (default).

    port indicates port-based load balancing.

    vif_name is the name of a previously created vif.

    interface_list is a list of the interfaces you want to add to the vif.

  2. To configure the vif, enter the following command: ifconfig vif_name IP_address netmask mask

Example

To create a static multimode vif, comprising interfaces e0, e1, e2, and e3 and using MAC address load balancing, enter the following command: vif create multi MultiTrunk1 -b mac e0 e1 e2 e3
