Creating a broadcast domain

You must create a broadcast domain for a custom IPspace. The SVMs created in the IPspace use the ports in the broadcast domain.

Before you begin

You must be a cluster administrator to perform this task.

About this task

The port to which a LIF fails over must be a member of the failover group for the LIF. When you create a broadcast domain, ONTAP automatically creates a failover group with the same name. The failover group contains all the ports assigned to the broadcast domain.

  1. Create a broadcast domain.

    Example

    network port broadcast-domain create -ipspace ipspace1 -broadcast-domain -ipspace1 -mtu 1500 -ports node1:e0d,node1:e0e,node2:e0d,node2:e0e
  2. Verify that the broadcast domain configuration is correct.
    1. Verify the broadcast domain is correct: network port broadcast-domain show
    2. Verify the network port is correct: network port show
    3. Verify the failover group names and failover targets are correct: network interface failover-groups show

    Example

    network port broadcast-domain show
