You can delete a broadcast domain by using System Manager when you no longer require the broadcast domain.
Before you begin
There must be no subnets associated with the broadcast domain that you want to delete.
About this task
When you delete a broadcast domain, the ports associated with it are assigned to the Default IPspace, and the MTU settings of the ports are not changed.
You cannot use System Manager to delete broadcast domains in the Cluster IPspace.
You must use the command-line interface instead.
Steps
Click the Network tab.
In the Broadcast Domains tab, select the broadcast domain that you want to delete, and then click Delete.
Select the confirmation check box, and then click
Delete.
