Creating a second-level interface group

You can create a second-level interface group by using two multimode interface groups. Second-level interface groups enable you to provide a standby multimode interface group in case the primary multimode interface group fails.

Before you begin

You must meet the following prerequisites to create a second-level interface group:

Steps

  1. Enter the following command to create the first of two multimode interfaces: ifgrp create multi -b {rr|mac|ip|port} ifgrp_name1 if1 if2
    The ifgrp_name1 interface group is composed of two physical interfaces, if1 and if2.
    -b—specifies the type of load-balancing method.
    rr—specifies the round-robin load-balancing option.
    mac—specifies the MAC address load-balancing option.
    ip—indicates the IP address load-balancing option (default option).
    port—indicates the port-based load-balancing option.
  2. Enter the following command to create the second of two multimode interfaces: ifgrp create multi -b {rr|mac|ip|port} ifgrp_name2 if3 if4
    The ifgrp_name2 interface group is composed of two physical interfaces, if3 and if4.
  3. Enter the following command to create a single-mode interface from the multimode interfaces: ifgrp create single ifgrp_name ifgrp_name1 ifgrp_name2
    ifgrp_name is the second-level interface group created with two multimode interface groups, ifgrp_name1 and ifgrp_name2.

Example

Use the following commands to create two interface groups and a second-level interface group. In this example, IP address load balancing is used for the multimode interface groups.

ifgrp create multi Firstlev1 e0 e1

ifgrp create multi Firstlev2 e2 e3

ifgrp create single Secondlev Firstlev1 Firstlev2
