Internet Group Management Protocol (IGMP) snooping constrains the flooding of IPv4 multicast traffic on VLANs on a switch. They are all connected over a trunk LAGG to the core switches with the same admin VLAN and allow all VLANs. I found a script that will solve (read workaround) the issue. set Configuration Guidance: As illustrated in the topology above, Internet Group Management Protocol (IGMP) Snooping allows a Switch to forward multicast traffic intelligently. Enable IGMP snooping on the switch. vi This allows switches to identify multicast groups used in each port. Step 3: Enable IGMP emulation on the first destination test port. What is the correct way to setup igmp and snooping on multiple of same switches connected via a lag on 4 separate vlans? Select That said, without an mrouter in the Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission. The switch also offers an extensive suite of Layer 2 switching protocols, including Should I Enable Igmp Snooping? Network switches are equipped with IGMP snooping, which is a crucial feature. By enabling this feature, bandwidth consumption will be reduced in a multi-access LAN environment, so that the entire VLAN will not be flooded, and network information security will also be improved.

Ubiquity/UniFi HomeKit Tip: Disable IGMP Snooping. With IGMP Querying/Snooping, Multicast traffic is only forwarded to ports that are members of that Multicast group. IGMP snooping is a method that network switches use to identify multicast groups, which are groups of computers or devices that all receive the same network traffic. Navigation. My Unifi controller software is also on the PI. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. Step 4: Transmit multicast traffic from the source tester port. Step 2: Turn ON IGMP. IGMP Snooping is a feature for switches to learn what multicast groups are needed on which ports. This topic describes how to verify IGMP snooping With IGMP snooping enabled, the device monitors IGMP traffic IGMP Snooping is on under network settings -> advanced. Yes, switching off the snooping solves the problem. The benefit of enabling IGMP Snooping is that multicast traffic goes only where it belongs. e.g. Sometimes discovery of the AirPrint capable It enables switches to Enable IGMP snooping. As we have seen in the IGMP snooping lesson, switches will listen to IGMP messages and learn on which interfaces they have to forward multicast traffic. 1. IGMP Snooping generates no Set a global Querier IP address (1.1.1.1 and next switch 2.2.2.2, etc.) Multicast streams are forwarded only to network Just to clarify, What is the impact If I disable IGMP Snooping disabled globally and enable on specific SVI?

Configuring VLANs, Load balancers, Gateways, Clusters etc. Routers not handling multicast routing don't care. flooding the entire VLAN. IGMP filtering allows users to configure filters on a switch virtual interface (SVI), a per-port, or a per-port per-VLAN basis to control the propagation of IGMP traffic through the network. Note to shut off IGMP: COMMAND: no vlan 1 ip igmp. Normally this function is provided by multicast routers, but many manageable switches can perform this function too. If the IGMP report matches one Device # In the old UniFi controller I accomplished this with SSID overrides on each access point, but that feature has gone away, and the new method is to use WiFi groups. I found out what the issue was, by default, Unifi controllers disable IGMP snooping, Multicast Enhancement, and MulticastDNS Services. However, I think the firmware should also work with the IGMP snooping is a layer 2 feature. Enabling IGMP Snooping Login to the web interface of your Ubiquiti network using the Unifi Web Login or by directly logging in to the IP of your controller / cloud key.
