Set Up a Static Router Port for IGMP Snooping
If your network does not include a device that sends IGMP queries, the switch cannot
discover the router port dynamically. (The router port is a port on a device in the network
that performs IGMP snooping in the network.) In this situation, select one port on the
switch as the dedicated static router port for IGMP snooping, allowing all IGMP Join
and Leave messages in the network to be forwarded to this port.
To set up a static router port for 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.
