You can use System Manager to create and manage broadcast domains.
Editing broadcast domains
You can use System Manager to modify the attributes of a broadcast domain, such as the name, the MTU size, and the ports associated with the broadcast domain.
Deleting broadcast domains
You can delete a broadcast domain by using System Manager when you no longer require the broadcast domain.
Configuring broadcast domains (cluster administrators only)
Broadcast domains enable you to group network ports that belong to the same layer 2 network. The ports in the group can then be used by a storage virtual machine (SVM) for data or management traffic.
