interface vlan

This command configures a VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. interface.

interface vlan ip igmp

This command enables IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. or IGMP snoopingIGMP snooping prevents multicast flooding on Layer 2 network by treating multicast traffic as broadcast traffic. Without IGMP snooping, all streams could be flooded to all ports on that VLAN. When multicast flooding occurs, end-hosts that happen to be in the same VLAN would receive all the streams only to be discarded without snooping. on this interface, or configures a VLANVirtual Local Area Network.
