Chapter 3 General Configuration and Monitoring
If the link is not present on both ports, the last active port will continue to remain as
active. If both the ports has connectivity but none of them is receiving any traffic,
then the RFGW-1 continuously changes the Active port to monitor for any traffic and
will lock to the port which receive the traffic first.
Revert to primary is not supported when the input ports are operating in this
detection mode.
Source Specific Multicast Operation in "Ethernet Link" and "Ethernet Link & UDP/L2TPv3"
Modes
The SSM operation is similar to the "4-port independent mode" except that the
sources will be tried on the current active port of the pair. The SSM operation also
works the same way in the manual redundancy mode.
Ethernet Link & UDP/L2TPv3 & TS Socket
This detection mode is also known as "Stream Redundancy" mode of operation. It
behaves the same way as the 'Ethernet Link & UDP/L2TPv3' mode except for
multicast input streams.
The unicast streams will continue to work the same way as in the 'Ethernet Link &
UDP/L2TPv3' mode. The virtual IP address of the port pair will continue to receive
unicast traffic only through the Current Active Port.
For Multicast streams, both the ports behave as active. i.e. input can be received
either from the backup port or the primary port irrespective of whether that port is
the Current Active port or not. The Virtual IP address will not be applicable for
multicast input streams. Both the ports in the port pair will receive multicast traffic
on their physical IP addresses
Since both the ports can be used to receive traffic at the same time, any multicast
input stream can be active on any of the port based on its availability. Different
sessions can be set up on different ports (of the port-pair) based on which port the
stream is available.
When a stream is configured, it will initially get setup on the primary port if it is
available. If it is not available on the primary port, it will get set on the backup port if
it is available. If the stream is lost on the currently bound port, then the RFGW-1 will
automatically switchover the stream to the other port. If a stream is not available on
both the ports (of the port pair), then it will be kept toggling between the two ports
until it becomes available on any of the port.
The IGMP Joins for multicast streams can be sent on one port or both the ports and is
configurable using the 'Multicast Join port',
Single port
Dual ports
