10.1.5 Seamless Input Redundancy
The Seamless IP input module allows two input interfaces to be connected to different network
sources, but for the system, this is a single module. Configured multicasts are subscribed to on
both interfaces. Depending on the configuration, there are options for these multicasts must
come from the same or different source.
10.1.5.1 Seamless IP Interface selection
For all Seamless IP input modules, it is possible to set the preferred port and/or redundancy
switching mechanism. This is available on the Admin page of the Seamless IP Input module:
Figure – 10.5 Seamless IP interface selection
The values here represent the following modes:
Floating
Port A is the default port and on a failure, Port B will be used. The
redundancy will not switch to Port A again until Port B fails.
Port A
Port A is the default port and on a failure Port B will be used. Once the
failure condition is cleared on Port A, the source will be switch back to
this. (Reverting)
Port B
Port B is the default port and on a failure Port A will be used. Once the
failure condition is cleared on Port B, the source will be switch back to
this. (Reverting)
10.1.5.2 Port configuration
When adding a source the default is that the multicast is configured by be received on both
input interfaces on the input card, i.e both Port A and Port B. These defaults may be overwritten
by editing the input. The following seamless specific attributes is shown in figure below.
