Mani,

This is one of the topics I am very interested, even though it is not
one of the R/S topics. I don't have access to a switch that has the
feature. But I would assume other ports not defined should be treated
as a completely different community port. So they are not allowed to
talk to other ports in other community as well as isolated. Anything
proved answer yet ?
