LANVIEWSECURE modules also provide a “Full security” configuration,
under which broadcast and multicast packets contain modified data fields
such as those used in eavesdrop prevention (described above). Ports set to
Full security mode will not see or respond to these types of packets. The
default setting for Full security is disabled. Enabling the Full security
function modifies the broadcast and multicast packets.
LANVIEW
SECURE is enabled upon the locking of a channel, module, or
port. When enabled, the first two addresses that are learned become the
expected addresses associated with that port on any LANVIEW
SECURE
module. If a port has never been enabled and a MAC address is added to
that port, then any MAC address learned on that port will be deleted
automatically. If a port is enabled and a new address is added to that port,
then any existing addresses remains in the expected address table.
