Command Line Interface Reference for the ProSafe 7200 Series Layer-2 Switches, Software Ver- 13.1.7.1 no ip igmp mrouter interface This command disables the forwarding of IGMP packets to a multicast router via this interface. Format no ip igmp mrouter interface Mode Interface Config 13.1.8 ip igmpsnooping unknown-multicast This command enables the filtering of unknown multicast packets to the VLAN. Packets with an unknown mulicast address in the destination field will be dropped. This command is mainly used when IGMP snooping is enabled, to prevent flooding of unwanted multicast packets to every port. Format ip igmpsnooping unknown-multicast Mode Global Config 13.1.8.1 no ip igmpsnooping unknown-mulitcast This command disables the filtering of unknown multicast packets. Unknown multicast packets will be flooded to all ports in the same VLAN. Format no ip igmpsnooping unknown-mulitcast Mode Global Config 13.2 IGMP Snooping Show Commands This section describes the commands you use to view IGMP snooping status and information. 13.2.1 show ip igmp This command displays IGMP Snooping information. Configured information is displayed whether or not IGMP Snooping is enabled. Format show ip igmp [ | ] Mode Privileged EXEC When the optional arguments or are not used, the command displays the following information: 13-6 v1.0, February 2007 IGMP Snooping Commands
