Configuring intercluster LIFs in custom IPspaces
You can configure intercluster LIFs in custom IPspaces. Doing so allows you to isolate replication traffic in multitenant environments.
About this task
Note
When you create a custom IPspace, the system creates a system storage virtual machine (SVM) to serve as a container for the system objects in that IPspace. You can use the new SVM as the container for any intercluster LIFs in the new IPspace. The new SVM has the same name as the custom IPspace.
- List the ports in the cluster: network port show For complete command syntax, see the man page (man <command_name>) or options (<command_name> ?).
Example
The following example shows the network ports in cluster01 :cluster01::> network port show
