Port-Isolate Enable - HP A5830 Series Command Reference Manual

port-isolate enable

Description
Use the port-isolate enable command to add a port or a group of ports to an isolation group as isolated
ports.
Use the undo port-isolate enable command to remove the port or ports from the isolation group.
In Layer 2 Ethernet interface view, the configuration applies to the current port.
In port group view, the configuration applies to all ports in the port group.
In Layer 2 aggregate interface view, the configuration applies to the Layer 2 aggregate interface and all
its member ports. After you make the configuration, the system starts applying the configuration to the
aggregate interface and its aggregation member ports. If the system fails to do that on the aggregate
interface, it stops applying the configuration to the aggregation member ports. If it fails to do that on an
aggregation member port, it simply skips the port and moves to the next port. For more information about
Layer 2 aggregate interfaces, see Layer 2
You can add a port to multiple isolation groups as an isolated port. However, you cannot configure an
isolated port in an aggregation group as the uplink port in any isolation group.
The member port of a service loopback group cannot be assigned to an isolation group and vice versa.
