1.1 Port Isolation Overview
1.1.1 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.
 Note:
z An isolation group only isolates the member ports in it.
z The port isolation function is independent of VLAN configuration.
1.1.2 Port Isolation and Link Aggregation
z When a port in an aggregation group joins an isolation group, the other ports in the
aggregation group join the isolation group automatically.
z When a port in an aggregation group leaves an isolation group, the other ports in
the aggregation group leave the isolation group automatically.
