M4200 -> M4300 Multicast Configuration (for NDI / Dante)
Hi all, I am not having any problems currently, but I wanted to run the config by this group and see if there's anything I'm missing or if any tweaks are in order... I have a M4200 with sever...
Thanks for the info... a few follow up questions:
- Am I correct to leave IGMP Snooping Querier Mode to Disable for the M4200 (but enabled on the M4300)? This does give me exactly one querier. I thought there should not be more than one querier on a network, or is that recommendation just for simplicity of not having to properly set up election priorities? I mean, in this sort of environment, if the querier is down, the switch is down and I have more problems....
- Also, I though that with the IGMP proxy mode enabled, there actually isn't a querier elected?
- One recommendation for NDI is to disable QoS? How is that done on these switches, and if I were to setup a VLAN for Dante, I'd need to disable for NDI VLAN and configure QoS for Dante VLAN (I've done this before).
Hi,
To answer.
1. Practicality suggests having more than one querier in the event of any failures on the network.
So can make sense to have both switches enabled as querier, but each with higher/lower IP values in the event of an election process.
2. Yes, by configuring all switches (and/or Routers) as IGMP proxy queriers, no designated IGMP querier is elected.
3. QoS isn't enabled by default on either switch model, so no need to specifically disable for NDI devices.
QoS can then be enabled for all Dante devices on the new VLAN.
I hope that helps answer your questions.
