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 into 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 isolation
group).
The ports in an isolation group must reside on the same switch or different units of an XRN fabric.
z Currently, you can create only on isolation group on a Switch 4500 series switch. The number of
Ethernet ports in an isolation group is not limited.
z An isolation group only isolates the member ports in it.
Port Isolation Configuration
You can perform the following operations to add an Ethernet port to an isolation group, thus isolating
Layer 2 and Layer 3 data among the ports in the isolation group.
