This object indicates the port's operational
status. The notPresent(3) status indicates the
port is physically removed (note this may or may
not be possible depending on the type of port.)
The operational(1) status indicates that the port
is enabled (see rptrPortAdminStatus) and working,
even though it might be auto-partitioned (see
rptrPortAutoPartitionState).
If this object has the value operational(1) and
rptrPortAdminStatus is set to disabled(2), it is
expected that this object's value will soon change
to notOperational(2).
