SETTINGS FOR MULTICAST
By default, the COM400 is set to provide a stable environment, however, if you are using the system to output IP
multicast video, a couple simple settings can be implemented for a more robust solution. These steps have been
tested and proven using a variety of managed Ethernet switches from well-known manufacturers. No other
advanced or further setup should be necessary for the COM400 and COM51 cards to work properly in a Multicast
environment.
If other specific settings are required by the managed Ethernet switch provider that you have selected, please
continue with caution and test in a lab environment before installation on a live site.
The recommended setting / actions are:
Verify the COM400 is running current software
Verify IGMP Snooping is enabled
Connect your managed Ethernet switch to one of the 10GbE ports (they can negotiate to 1GbE)
Enable Router Port for the port connected to the managed Ethernet switch
Keep it simple. Don't depend on advanced settings or modes
Persistently save your settings
IGMP Settings
From the main menu navigate to:
Configuration > IMPC > IGMP snooping > Basic Configuration
Verify
Snooping Enabled
is checked. If not, check the box and then click
Save.
Fast Leave
should be unchecked unless a STB is connected directly to the COM400.
Select
Router Port
for the port connected to your core switch. This will allow all Multicast traffic through the
port. The external switch can then handle all IGMP functions.
