LAN Redundancy
LAN redundancy enables the redundant LAN port connection to automatically replace the
failed port by using another physical connection and NIC (Network Interface Card). When a
LAN port fails, IP network traffic failure is averted and network or endpoints
disconnections do not occur. When LAN redundancy is enabled, by default, LAN 1 is the
active port and LAN 2 is its backup.
Requirements
LAN redundancy is disabled by default. However, you can change its availability by setting
the LAN_REDUNDANCY system flag.
