Broadcast domains are automatically created during the cluster create or join operation. You do not need to manually remove ports from broadcast domains.

If network port reachability has changed, either through physical network connectivity or switch configuration, and a network port belongs in a different broadcast domain, see the following topic:

Repair port reachability

System Manager

Beginning with ONTAP 9.14.1, you can use System Manager to reassign Ethernet ports across broadcast domains. It is recommended that you assign every Ethernet port to a broadcast domain. So, if you unassign an Ethernet port from a broadcast domain, you must reassign it to a different broadcast domain.

Steps

To reassign Ethernet ports, perform the following steps:

  1. Select Network > Overview.

  2. In the Broadcast Domains section, select Menu options icon next to the domain name.

  3. In the drop-down menu, select Edit.

  4. On the Edit Broadcast Domain page, deselect the Ethernet ports that you want to reassign to another domain.

  5. For each deselected port, the Reassign Ethernet Port window displays. Select the broadcast domain to which you want to reassign the port, and then select Reassign.

  6. Select all the ports that you want to assign to the current broadcast domain and save your changes.
