System Settings for Multicasting
The System Settings for Multicasting detailed below are accessible
via either the remote control, WebView or Front Panel interfaces.
Client Enable:
Allows option to enable or disable the multicast client.
Note that if you make changes to other Multicast settings, you
must also toggle the Client Enable setting from “Disabled” to
“Enabled” for the changes to apply.
Listen Address:
The IP address that the multicast client will listen on. The value
must be a Class D multicast address, which will typical start with
224.xxx.xxx.xxx.
Because some addresses may be reserved (see below), consult your
networking specialist for assistance.
224.0.0.0/24 is reserved by RFC.
224.0.1.0/24 is used by specific applications (NTP).
Listen Port:
The port address that the multicast client will listen on.
Transfer Order:
Allows the option to choose the order in which items are
transferred: package mode (see page 109 for details) or script last
mode (see page 110 details).
Reserves MBs:
Allows you to allocate a fixed amount of Firefly’s internal storage
space for receiving a multicast update. To determine this value,
you will need to estimate the largest multicast update you will ever
receive (example: 1000 MBs). Then, double that amount (example:
1000 MBs x 2 = 2000 MBs) to allow room for both the
compressed archive and the extraction process. Once you have
determined this value, enter it for the Reserve MBs.
