1402 Managing IPv4 and IPv6 MulticastConfiguring and Viewing IGMPBeginning in Privileged EXEC mode, use the following commands toconfigure IGMP on the switch and on VLAN routing interfaces and to viewIGMP information.Command Purposeconfigure Enter global configuration mode.ip multicast Enable IPv4/IPv6 multicast routing.ip igmp Enable IGMP on the switch.interface vlanvlan-id Enter Interface Configuration mode for the specifiedVLAN.ip igmp Enable IGMP on the interface.ip igmp versionversion Set the version of IGMP for an interface.Theversion variable can be 1, 2, or 3.ip igmp robustnessrobustnessConfigure the robustness that allows tuning of theinterface, that is, tuning for the expected packet loss on asubnet. If a subnet is expected to have significant loss, therobustness variable may be increased for the interface.The range forrobustness is 1–255.ip igmp query-intervalsecondsConfigure the query interval for the specified interface.The query interval determines how fast IGMP Host-Query packets are transmitted on this interface.The range forseconds is 0–3600 seconds.ip igmp query-max-response-timesecondsConfigure the maximum response time interval for thespecified interface. It is the maximum query responsetime advertised in IGMPv2 queries on this interface.The range forseconds is 0–25 seconds.ip igmp startup-query-intervalsecondsSet the interval between general queries sent at startup onthe interface.The range forseconds is 0–300 seconds.
