Description
Use the port isolate command to add an Ethernet port to the isolation group.
Use the undo port isolate command to remove an Ethernet port from the isolation
group.
Note:
When the port isolate command or undo port isolate command is executed, the
other ports which are in the same aggregation group with the current port in the local
unit will be added to or removed from the isolation group together at the same time.
By default, an isolation group contains no port.
