OS10-L2S-000170 - The Dell OS10 Switch must have IGMP or MLD Snooping configured on all VLANs
Information
IGMP and MLD snooping provides a way to constrain multicast traffic at Layer 2. By monitoring the IGMP or MLD membership reports sent by hosts within a VLAN, the snooping application can set up Layer 2 multicast forwarding tables to deliver specific multicast traffic only to interfaces connected to hosts interested in receiving the traffic, thereby significantly reducing the volume of multicast traffic that would otherwise flood the VLAN.Solution
Configure IGMP or MLD snooping for IPv4 and IPv6 multicast traffic respectively for each VLAN.Enable IGMP or MLD snooping globally:
OS10(config)# ip igmp snooping enable
OS10(config)# ipv6 mld snooping enable
Enable IGMP or MLD snooping on each VLAN:
OS10(config)# interface vlan 100
OS10(conf-if-vl-100)# ip igmp snooping
OS10(conf-if-vl-100)# ipv6 mld snooping
