This object holds an encoded, human-readable-style list of the ports, such as 1/0/1-5,1/0/9-11,1/0/16, that the isolated port above is still permitted to forward traffic to. An admin edits this to control exactly which other ports an isolated port can still reach, typically limiting it to only an uplink or gateway port while blocking peer-to-peer traffic to everything else. For example, setting the value to 1/0/1 would restrict that isolated port to communicating only with port 1/0/1, and nothing else.
