Port Isolation Configuration Example; Displaying And Maintaining Port Isolation Configuration - 3Com 5500-EI PWR Install Manual

When a member port of an aggregation group joins/leaves an isolation group, the other ports in the
same aggregation group will join/leave the isolation group at the same time.
For ports that belong to an aggregation group and an isolation group simultaneously, removing a
port from the aggregation group has no effect on the other ports. That is, the rest ports remain in
the aggregation group and the isolation group.
Ports that belong to an aggregation group and an isolation group simultaneously are still isolated
even when you remove the aggregation group in system view.
Adding an isolated port to an aggregation group causes all the ports in the aggregation group on
the local unit to be added to the isolation group.
Switch 5500-EI supports cross-device port isolation if XRN fabric is enabled.
For Switch 5500-EI belonging to the same XRN Fabric, the port isolation configuration performed
on a port of a cross-device aggregation group cannot be synchronized to the other ports of the
aggregation group if the ports reside on other units. That is, to add multiple ports in a cross-device
aggregation group to the same isolation group, you need to perform the configuration for each of
the ports individually.
