Chapter 15 IGMP Snooping Commands This section describes the Internet Group Management Protocol (IGMP) snooping commands available in the 7300S Series Stackable Switch CLI. The 7300S Series Stackable Switch supports IGMP Versions 1, 2, and 3. The IGMP snooping feature can help conserve bandwidth because it allows the switch to forward IP multicast traffic only to connected hosts that request multicast traffic. IGMPv3 adds source filtering capabilities to IGMP versions 1 and 2. This section contains the following topics: • Section 15.1 "IGMP Snooping Configuration Commands" on page 15-1 • Section 15.2 "IGMP Snooping Show Commands" on page 15-6 • Section 15.3 "IGMP Querier Commands" on page 15-9 The commands in this section are in one of two groups: • Show commands are used to display switch settings, statistics and other information. • Configuration Commands are used to configure features and options of the switch. For every configuration command there is a show command that will display the configuration setting. 15.1 IGMP Snooping Configuration Commands This section describes the commands you use to configure IGMP snooping. 15.1.1 ip igmpsnooping This command enables IGMP Snooping on the system (Global Config Mode) or an interface (Interface Config Mode). This command also enables IGMP snooping on a particular VLAN and can enable IGMP snooping on all interfaces participating in a VLAN. IGMP Snooping Commands v3.0, January 2008 15-1
