■

Adding to or removing from an isolation group an aggregated port can cause 
all other ports in the aggregation group on the device to join or exit the 
isolation group automatically.

■

After an aggregated port is removed from its aggregation group, all other 
member ports will still stay in the isolation group that they have joined (if any).

■

Removing an aggregation group does not remove its member ports from the 
isolation group that they have joined (if any).

■

Adding an isolated port to an aggregation group can cause all the member 
ports in the aggregation group to join the isolation group automatically.

■

Cross-device port isolation is supported on the Switch 5500 in an XRN fabric. 
This allows ports on different units to join the same isolation group.

■

For the Switch 5500 in an XRN fabric, adding a member port in a cross-device 
aggregation group to an isolation group does not cause other member ports to 
join the isolation group automatically. For them to join the isolation group, you 
need to perform the configuration manually for each of them.
