Network configuration guidelines

Switch features and configurations vary between manufacturers. Refer to the manufacturer's user manual when configuring the required features to support MoIP.

Caution: Configure the network before connecting MoIP devices to avoid network flooding and overall instability.

Terms to understand

  • Core Network Switch — The backbone of your local area network. This switch connects directly to your router and all other switches connect to this switch.

  • Edge Network Switch — A switch connected to your Core Network switch.

  • Core MoIP Switch — This is where your MoIP network starts. Think of it as its own topology within the larger network, dedicated to the MoIP.

  • Edge MoIP Switch — A switch connected to your Core MoIP switch.

  • IGMP Snooping — This switch function listens for Internet Group Management Protocol (IGMP) messages to create an internal list of what devices have requested which IP multicast transmissions to be forwarded to them.

  • IGMP Snooping Querier — Periodically requests all client devices on the network to report in with the multicast groups they wish to be joined with, to make sure that the IGMP snooping groups are updated to prevent multicast traffic loss.

  • Multicast Routing — The forwarding of multicast traffic between segments of a network. Primarily VLANs and the LAN.

  • Unregistered Multicast — Multicast traffic sent across a network that has had no IGMP messages associated with it. A network switch can decide to continue flooding this traffic through the network or to drop this traffic until an IGMP message has been seen for that multicast group.

  • Fast Leave — A network switch function that causes a port to act on an IGMP leave message to remove the associated multicast group from the port without waiting for the normal leave to expire.

You must apply the following settings to all the managed switches in the network: 

  • IGMP snooping must be enabled and set to v2. 

  • Unregistered multicast behavior set to drop.

  • MRouter/Router Auto-learn enabled.

  • Fast Leave enabled on the Araknis 920 switch ports with B-960 devices connected to them. This does not include switch uplinks or the MoIP Controller.

The core MoIP switch must have:

  • Querier state enabled and set to v2.

  • The lowest IP address among any switches with the querier state enabled or participating in querier election participation.

Edge switches must have the following settings configured: 

  • Querier state disabled.

Caution: Ryff to MoIP does not currently support VLANs.

Follow these guidelines when isolating MoIP to a VLAN:

  • When configuring a MoIP VLAN, make sure your IGMP settings are only enabled for the MoIP VLAN and not the rest of the network.

  • Configure Trunk ports between the router and switch to allow VLAN Traffic to flow to the MoIP switches.

  • MoIP devices must be connected to MoIP VLAN Access Ports.

  • When sharing a switch with Control4 and MoIP, enable IGMP on the MoIP and Control4 VLAN.
