IGMP general operation and features

In a network where IP multicast traffic is transmitted for various multimedia applications, you can use the switch to reduce unnecessary bandwidth usage on a per-port basis by configuring IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups.. In the factory default state (IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. disabled), the switch simply floods all IP multicast traffic it receives on a given VLAN through all ports on that VLAN (except the port on which it received the traffic.) This can result in significant and unnecessary bandwidth usage in networks where IP multicast traffic is a factor. Enabling IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. allows the ports to detect IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. queries and report packets and manage IP multicast traffic through the switch.

IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. is useful in multimedia applications such as LAN Local Area Network. LAN is a computer network that is used to connect devices within a limited geographical area, such as a home, office, or school. LANs can be wired or wireless, and they can be configured in different topologies, such as bus, star, or mesh. TV, desktop conferencing, and collaborative computing, where there is multipoint communication, that is, communication from one to many hosts, or communication originating from many hosts and destined for many other hosts. In such multipoint applications, IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. is configured on the hosts, and multicast traffic is generated by one or more servers (inside or outside of the local network.) Switches in the network (that support IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups.) can then be configured to direct the multicast traffic to only the ports where needed. If multiple VLANs are configured, you can configure IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. on a per-VLAN basis.

IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. queries and report packets used to manage IP multicast traffic through the switch. If no other querier is detected, the switch then also functions as the querier. If you need to disable the querier feature, you can do so using the IGMP Internet Group Management Protocol. IGMP is a network-layer protocol that is used by hosts to report their multicast group memberships to neighbouring routers. IGMP is used by hosts to join and leave multicast groups, and by routers to learn which hosts are members of which multicast groups. configuration CLI commands, see Configuring the querier function.
