Port Isolation Overview
The port isolation feature is used to secure and add privacy to the data traffic and prevent malicious
attackers from obtaining the user information. With the port isolation feature, you can add the ports to be
controlled int o an isolation group to isolate the Layer 2 and Layer 3 data between each port in the
isolation group (a port in an isolation group does not forward traffic to the other ports in the isola
gro up).
The ports in a n isolation group must reside on the same switch or different units of an XRN fabric
Currently, you can create only on isolation group on a Switch 4500. The number of Ethernet ports
in an isolation group is not limited.
An isolation group only isolates the member ports in it.
