Manage Multicast

Multicast IP traffic is traffic that is destined to a host group. Host groups are identified by Class D IP addresses,
which range from 224.0.0.0 to 239.255.255.255. Internet Group Management Protocol (IGMP) snooping
allows the switch to forward multicast traffic intelligently. Based on the IGMP query and report messages,
the switch forwards traffic only to the ports that request the multicast traffic rather than to all ports, which
could affect network performance.
IGMP snooping helps to optimize multicast performance and is especially useful for bandwidth-intensive IP
multicast applications such as online media streaming applications.

Manage IGMP Snooping

Internet Group Management Protocol (IGMP) snooping is enabled by default. Under some circumstances
you might want to temporarily disable IGMP snooping.
To manage IGMP snooping:
1. Open a web browser from a computer that is connected to the same network as the switch or to the
switch directly through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
The login page displays.
