Before you can configure a broadcast domain to add to the new IPspace, you must determine what ports are available for the broadcast domain.
Before you begin
You must be a cluster administrator to perform this task.
About 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.
Example
network port showNode 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 , and e0g 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.

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 on e0c on node1.
Ports e0d , e0e , e0f , and e0g 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.
