Configuring port isolation

Assigning access ports to different VLANs is a typical way to isolate Layer 2 traffic for data privacy and
security, but this approach is demanding on VLAN resources. To isolate Layer 2 traffic without using
VLANs, HP introduced the port isolation feature.
To use the feature, you assign ports to a port isolation group. Ports in an isolation group are called
―isolated ports.‖ An isolated port does not forward any Layer 2 traffic to any other isolated port on the
same switch, even if they are in the same VLAN. Still, an isolated port can communicate with any other
port outside the isolation group, provided that they are in the same VLAN.
The switch supports one isolation group called ―isolation group 1.‖ This isolation group is created
automatically and cannot be deleted. There is no limit on the number of member ports.

3. Assign the port or ports to the
isolation group as an isolated
