KDS-4 Multicast Stream Issues

Issue:

When using KDS-4, multicast stream is not working while Unicast stream works well.

Solution:

In general, we recommended that you use an unmanaged switch when using KDS-4.
KDS-4 may have an issue with backpressure on the side of the encoder connection to the switch if it is a managed switch, for example, for example a Cisco switcher.
Using 1Gbs is too high for the interface of the encoder, so you need to configure the back pressure.
If you are using a Cisco switcher between the encoder and decoder, you *MUST *configure the backdrop pressure at the cisco ports where the devices are connected.

Configuring the cisco switch interface (the rx flowcontrol) solves the problem for1Gbs.
To configure the switcher:

1. Switch# configure terminal.
2. Switch(config)# interface gigabitethernet1/0/1.
3. Switch(config-if)# flowcontrol receive on.
4. Switch(config-if)# end.
   

In addition, enable the following in the managed switch:

• IGMP snooping.
• IGMP fast leave.
  

Note: When using KDS-4 in Unicast, no Network settings are required.
