CHAPTER 1: INTRODUCTION

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.

LANVIEWSECURE 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 LANVIEWSECURE 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.
