M4300 Intelligent Edge Series Fully Managed Stackable Switches no set igmp This command disables IGMP Snooping on the system, an interface, a range of interfaces, or a VLAN. Format Mode no set igmp [vlan-id] Global Config Interface Config VLAN Config set igmp interfacemode This command enables IGMP Snooping on all interfaces. If an interface has IGMP Snooping enabled and you enable this interface for routing or enlist it as a member of a port-channel (LAG), IGMP Snooping functionality is disabled on that interface. IGMP Snooping functionality is re-enabled if you disable routing or remove port-channel (LAG) membership from an interface that has IGMP Snooping enabled. Default Format Mode Disabled set igmp interfacemode Global Config no set igmp interfacemode This command disables IGMP Snooping on all interfaces on the switch at the same time. It is disabled by default. This command does not take effect on the interface where routing is enabled or is a member of a port-channel (LAG). Disable routingon the interface before setting IGMP Snooping. The interface that is a member of a port-channel (LAG) must be removed before setting IGMP Snooping Default Format Mode Disabled no set igmp interfacemode Global Config set igmp fast-leave This command enables or disables IGMP Snooping fast-leave on a selected interface, a range of interfaces, or a VLAN. When you enable fast-leave, the switch immediately removes a layer 2 LAN interface from its forwarding table if the following situation occurs: 1. The switch does not send MAC-based general queries to the layer 2 LAN interface. 2. The switch receives an IGMP leave message for the associated multicast group. Enable fast-leave only on VLANs for which a single host is connected to each layer 2 LAN interface. Doing so prevents the inadvertent dropping of other hosts that are connected to the Switching Commands 563 CLI Command Reference Manual
