Port Isolation
Overview
Introduction to Port
Isolation
Through the port isolation feature, you can add the ports to be controlled into an
isolation group to isolate Layer 2 and Layer 3 data between ports in the isolation
group. Thus, it can improve network security and deliver flexible networking
solutions.
Currently, you can configure 64 isolation groups on a switch. The number of
Ethernet ports an isolation group can accommodate is not limited.

■
An isolation group only isolates the member ports in it.
■
The port isolation function is independent of VLAN configuration.
Port Isolation and Link
Aggregation
■
When a port in an aggregation group joins an isolation group, the other ports
in the aggregation group join the isolation group automatically.
■
When a port in an aggregation group leaves an isolation group, the other ports
in the aggregation group leave the isolation group automatically.
