Merge ONTAP broadcast domains

If network port reachability has changed, either through physical network connectivity or switch configuration, and two group of network ports previously configured in multiple broadcast domains now all share reachability, then merging two broadcast domains can be used to synchronize the ONTAP configuration with the physical network topology.

Note The procedure for merging broadcast domains is different in ONTAP 9.7 and earlier versions. If you need to merge broadcast domains on a network running ONTAP 9.7 and earlier, refer to Merge broadcast domains (ONTAP 9.7 or earlier).

To determine if multiple broadcast domains belong to one reachability set, use the network port reachability show -details command and pay attention to which ports that are configured in another broadcast domain actually have connectivity to one another ("Unexpected ports"). Typically, the list of unexpected ports defines the set of ports that should be merged into the broadcast domain after you have verified that the physical and switch configuration is accurate.

Learn more about network port reachability show in the ONTAP command reference.

Step

Merge the ports from one broadcast domain into an existing broadcast domain:

network port broadcast-domain merge -ipspace <ipspace_name> -broadcast-domain <broadcast_domain_name> -into-broadcast-domain <broadcast_domain_name>

  • ipspace_name is the name of the ipspace where the broadcast domains reside.

  • -broadcast-domain is the name of the broadcast domain that will be merged.

  • -into-broadcast-domain is the name of the broadcast domain that will receive additional ports.
