M4300 Intelligent Edge Series Fully Managed Stackable Switches same layer 2 LAN interface but are still interested in receiving multicast traffic that is directed to the multicast group. Fast-leave processing is supported for IGMPv2 hosts only. Default Format Mode Enabled for VLAN 1; Disabled for other VLANs. set igmp fast-leave [vlan-id] Interface Config Interface Range VLAN Config no set igmp fast-leave This command disables IGMP Snooping fast-leave admin mode on a selected interface. Format Mode no set igmp fast-leave [vlan-id] Interface Config Interface Range VLAN Config set igmp fast-leave auto-assignment This command globally enables or disables the automatic assignment of fast-leave for all ports and LAGs. On the switch, Rapid Spanning Tree Protocol (RSTP) is the default network protocol for STP. RSTP functions at port level. Each port starts up as an edge port and functions in that capacity until it receives an RSTP BPDU from a neighbor device. An edge port does not participate in STP and is meant to be connected to end devices or hosts on which STP is not enabled. However, if a port receives an RSTP BPDU, the port stops functioning as an edge port and starts participating in STP. Consequently, as long as the port functions as an edge port, IGMP Snooping fast-leave is enabled. If a port receives an RSTP BPDU and stops functioning as an edge port, IGMP Snooping fast-leave is also disabled on the port. The set igmp fast-leave auto-assignment command controls the fast-leave operational state, but not the configured value. On a port, a dynamically-assigned operational value for fast-leave overrides a configured value for fast-leave. The set igmp fast-leave auto-assignment command does the following: • It overrides the configured port level fast-leave mode, which is disabled by default. • It does not modify the VLAN configuration for fast-leave mode. Between a port and a VLAN that is configured for that port, IGMP Snooping gives precedence to the fast-leave mode for the port. Switching Commands 564 CLI Command Reference Manual
