Hardware Monitor Indications
When LAN Redundancy is enabled on the RMX, LAN 2 port is Active. With LAN
redundancy, when LAN LEDs are lit they indicate that a physical connection of the cables is
present but does not indicate their activity status. In the Hardware Monitor pane the Lan List
displays the RMX LAN ports together with their Status indication.
Network Traffic Control
A Network Traffic Control mechanism has been added to the RMX that controls the level of
UDP packets generated by the system.
Network Traffic Control regulates a set of queuing systems and mechanisms by which UDP
packets are received and “transmitted” to the network router. During a conference the
MPMx cards occasionally blast-out UDP packets which can cause overloads on the network.
RMX bandwidth usage can increase to above the designated conference participant line rate
settings, causing network bandwidth issues such as latency and packet loss.
LAN_REDUNDANCY = YES
MULTIPLE_SERVICES = YES
