IGMP snooping querier overview
IGMP snooping requires that one central switch or router periodically query all end-devices
on the network to announce their multicast memberships. This central device is the IGMP
querier. The IGMP query responses, known as IGMP reports, keep the switch updated with
the current multicast group membership on a port-by-port basis. If the switch does not
receive updated membership information in a timely fashion, it stops forwarding multicasts to
the port where the end device is located.
You can configure and display information about IGMP snooping queriers on the network
and, separately
, on VLANs.
Configure an IGMP snooping querier
You can configure the settings for an IGMP snooping querier.
To configure the settings for an IGMP snooping querier:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
