Before you can configure a broadcast domain to add to the new IPspace, you must determine what ports are available for the broadcast domain.
This task is relevant for ONTAP 9.0 - 9.7, not ONTAP 9.8. |
You must be a cluster administrator to perform this task.
-
Ports can be physical ports, VLANs, or interface groups (ifgroups).
-
The ports that you want to add to the new broadcast domain cannot be assigned to an existing broadcast domain.
-
If the ports that you want to add to the broadcast domain are already in another broadcast domain (for example, the Default broadcast domain in the Default IPspace), you must remove the ports from that broadcast domain before assigning them to the new broadcast domain.
-
Ports that have LIFs assigned to them cannot be removed from a broadcast domain.
-
Because the cluster management and node management LIFs are assigned to the Default broadcast domain in the Default IPspace, the ports assigned to these LIFs cannot be removed from the Default broadcast domain.
-
Determine the current port assignments.

Node Port IPspace Broadcast Domain Link MTU Admin/Oper ------ ---- ------- ---------------- ----- ---- ------------ node1 e0a Cluster Cluster up 9000 auto/1000 e0b Cluster Cluster up 9000 auto/1000 e0c Default Default up 1500 auto/1000 e0d Default Default up 1500 auto/1000 e0e Default Default up 1500 auto/1000 e0f Default Default up 1500 auto/1000 e0g Default Default up 1500 auto/1000 node2 e0a Cluster Cluster up 9000 auto/1000 e0b Cluster Cluster up 9000 auto/1000 e0c Default Default up 1500 auto/1000 e0d Default Default up 1500 auto/1000 e0e Default Default up 1500 auto/1000 e0f Default Default up 1500 auto/1000 e0g Default Default up 1500 auto/1000
In this example, the output from the command provides the following information:
-
Ports
e0c
,e0d
,e0e
,e0f
, ande0g
on each node are assigned to the Default broadcast domain. -
These ports are potentially available to use in the broadcast domain of the IPspace that you want to create.
-
-
Determine which ports in the Default broadcast domain are assigned to LIF interfaces, and therefore cannot be moved to a new broadcast domain.

Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ------- ---------- ---------- ------------ --------- ------- ---- Cluster node1_clus1 up/up 10.0.2.40/24 node1 e0a true node1_clus2 up/up 10.0.2.41/24 node1 e0b true node2_clus1 up/up 10.0.2.42/24 node2 e0a true node2_clus2 up/up 10.0.2.43/24 node2 e0b true cluster1 cluster_mgmt up/up 10.0.1.41/24 node1 e0c true node1_mgmt up/up 10.0.1.42/24 node1 e0c true node2_mgmt up/up 10.0.1.43/24 node2 e0c true
In the following example, the output from the command provides the following information:
-
The node ports are assigned to port
e0c
on each node and the cluster administrative LIF's home node is one0c
onnode1
. -
Ports
e0d
,e0e
,e0f
, ande0g
on each node are not hosting LIFs and can be removed from the Default broadcast domain and then added to a new broadcast domain for the new IPspace.
