Example of using broadcast domains
A broadcast domain is a set of network ports in the same IPspace that also has layer 2 reachability to one another, typically including ports from many nodes in the cluster.
The illustration shows the ports assigned to three broadcast domains in a four-node cluster:
The Cluster broadcast domain is created automatically during cluster initialization, and it contains ports a and b from each node in the cluster.
The Default broadcast domain is also created automatically during cluster initialization, and it contains ports c and d from each node in the cluster.
The bcast1 broadcast domain has been created manually, and it contains ports e, f, and g from each node in the cluster.
This broadcast domain was created by the system administrator specifically for a new client to access data through a new SVM.
A failover group of the same name and with the same network ports as each of the broadcast domains is created automatically. This failover group is automatically managed by the system, meaning that as ports are added or removed from the broadcast domain, they are automatically added or removed from this failover group.
