PORT ISOLATION CONFIGURATION
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 the Layer 2 and Layer 3 data between each port in the
isolation group. Thus, you can improve the network security and network in a
more flexible way.
Currently, you can configure 64 isolation groups on a switch. The number of
Ethernet ports an isolation group can accommodate is not limited.
n
The port isolation function is independent of VLAN configuration.
Port Isolation and Link
Aggregation
When a member port in an aggregation group joins an isolation group, the other
ports in the aggregation group joins the isolation group automatically.
Port Isolation
Configuration
Table 120 lists the operations to add an Ethernet port to an isolation group to
isolate Layer 2 data between each port in the isolation group.
n
An Ethernet port belongs to only one port isolation group. If you add an Ethernet
port to different isolation groups, the port belongs to only the latest isolation
group to which the port is added.
