LAN Redundancy<br />

<strong>Guide</strong>lines<br />

LAN Port Redundancy is available on the <strong>RMX</strong> 1500/<strong>2000</strong>/4000. LAN Redundancy enables<br />

the redundant LAN port connection to automatically replace the failed port by using<br />

another physical connection and NIC (Network Interface Card). When a LAN port fails, IP<br />

network traffic failure is averted and network or endpoints disconnections do not occur. For<br />

example, on <strong>RMX</strong> 1500 should the LAN 2 port fail on the RTM IP, then LAN 1 is available as<br />

a backup.<br />

On <strong>RMX</strong> <strong>2000</strong>/4000 should the LAN 2 port fail on the RTM LAN card, then LAN1 is<br />

available as a backup.<br />

Redundant LAN 1 port<br />

The LAN redundancy feature is enable (YES by default) or disabled by the flag<br />

LAN_REDUNDANCY.<br />

• On the <strong>RMX</strong> 1500, LAN redundancy cannot be enabled in parallel to Multiple<br />

Networks.<br />

• On <strong>RMX</strong> <strong>2000</strong>/4000, when Multiple Networks option is enabled and the RTM LAN<br />

ports are not assigned to any network, then the LAN 1 port is redundant by default.<br />

• On <strong>RMX</strong> <strong>2000</strong>/4000 the redundant default port is LAN 1 on the RTM LAN.<br />

• On the <strong>RMX</strong> 1500, LAN ports can used as follows:<br />

— LAN 2 port is used for standard communications<br />

— LAN 1 port can be used to define a second Network Service or used for LAN<br />
