Configuring Port Isolation; Assigning A Port To The Isolation Group; Displaying And Maintaining The Isolation Group - HP 5120 EI Series Lan Switching Configuration Manual

Configuring port isolation

Port isolation enables isolating Layer 2 traffic for data privacy and security without using VLANs. You can
also use this feature to isolate the hosts in a VLAN from one another.
To use the feature, assign ports to a port isolation group. Ports in an isolation group are called "isolated
ports." One isolated port cannot forward Layer 2 traffic to any other isolated port on the same switch,
even if they are in the same VLAN. An isolated port can communicate with any port outside the isolation
group if they are in the same VLAN.
The switch series supports only one isolation group "isolation group 1." The isolation group is
automatically created and cannot be deleted. There is no limit on the number of member ports.

Assigning a port to the isolation group

Step
1. Enter system view.
2. Enter interface view or port
group view.
3. Assign the port or ports to the
isolation group as an isolated
port or ports.
