Lan Redundancy - Polycom realpresence 1800 Administrator's Manual

LAN Redundancy

LAN Redundancy enables the redundant LAN port connection to automatically replace the failed LAN 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 cables are
connected to both LAN 1 and LAN 2 ports, the RMX automatically selects which port is active and which is
redundant.
Media Redundancy - Collaboration Server (RMX) 2000/4000
On the RealPresence Collaboration Server (RMX) 2000 and RealPresence Collaboration Server (RMX)
4000, the LAN 1 and LAN 2 port on the RTM LAN card can be used as redundant media ports.
RealPresence Collaboration Server (RMX) 2000/4000 RTM LAN Card on Rear Panel
Media Redundancy on the RealPresence Collaboration Server (RMX) 2000/4000 is dependent on the
settings of the LAN_REDUNDANCY and MULTIPLE_SERVICES System Flags as summarized in the
following table:
RMX 2000 / 4000 - Media Redundancy - System Flags
System Flag / Value
LAN_REDUNDANCY
MULTIPLE_SERVICES = NO
LAN_REDUNDANCY
MULTIPLE_SERVICES = YES
LAN_REDUNDANCY
MULTIPLE_SERVICES = NO
LAN_REDUNDANCY
MULTIPLE_SERVICES = YES
Media Redundancy is not supported on any of the RMX RTM ISDN cards.
Media and Signaling Redundancy - Collaboration Server (RMX) 1800
On the RealPresence Collaboration Server 1800 LAN 1 and LAN 2 are the redundant media and signaling
ports:
● LAN 1 port is used for standard communications
● LAN 2 port can be used to define a second Network Service or for LAN Redundancy
