Limiting the Rate of IGMP Join Requests Limit the number of new groups that can be joined per second using the command ip igmp group-join-limit from INTERFACE mode. View the enable status of this feature using the command show ip igmp interface from EXEC Privilege mode, as shown in Figure 415. Enabling IGMP Immediate-leave If the querier does not receive a response to a group-specific or group-and-source query, it sends another (Querier Robustness Value). Then, after no response, it removes the group from the outgoing interface for the subnet. You can configure the system to remove specified groups after the first query to reduce leave latency using the command ip igmp immediate-leave. View the enable status of this feature using the command show ip igmp interface from EXEC Privilege mode, as shown in Figure 415. 592 Internet Group Management Protocol
IGMP Snooping IGMP Snooping versions 1 and 2 are supported on platforms: c e s IGMP Snooping version 3 is supported only on platform e Multicast packets are addressed with multicast MAC addresses, which represent a group of devices, rather than one unique device. Switches forward multicast frames out of all ports in a VLAN by default, even though there may be only some interested hosts, which is a waste of bandwidth. IGMP Snooping enables switches to use information in IGMP packets to generate a forwarding table that associates ports with multicast groups so that when they receive multicast frames, they can forward them only to interested receivers. IGMP Snooping Implementation Information • IGMP Snooping on FTOS uses IP multicast addresses not MAC addresses. • IGMP snooping is not supported on stacked VLANs, or with stacking on the S-Series. • IGMP snooping reacts to STP and MSTP topology changes by sending a general query on the interface that transitions to the forwarding state. Configuring IGMP Snooping Configuring IGMP Snooping is a one-step process. That is, enable it on a switch using the command ip igmp snooping enable from CONFIGURATION mode. View the configuration using the command show running-config from CONFIGURATION mode, as shown in Figure 417. You can disable snooping on for a VLAN using the command no ip igmp snooping from INTERFACE VLAN mode.
