PORT ISOLATION CONFIGURATION

8 GUIDE

Configuring Port

Port isolation allows you to add a port into an isolation group to isolate Layer-2

Isolation

and Layer-3 traffic of the port from that of all other ports in the isolation group.

 

While increasing network security, this allows for great flexibility.

 

Currently, the Switch 5500 supports only one isolation group; however, the

 

number of Ethernet ports in the isolation group is not limited.
