Layer 2 IGMP (Snooping and Query)
– 473 –
This attribute configures the IGMP report/query version used by IGMP
snooping. Versions 1 - 3 are all supported, and versions 2 and 3 are backward
compatible, so the switch can operate with other devices, regardless of the
snooping version employed.
◆ Querier Status – When enabled, the switch can serve as the Querier, which is
responsible for asking hosts if they want to receive multicast traffic. This feature
is not supported for IGMPv3 snooping. (Default: Disabled)
Web Interface
To configure general settings for IGMP Snooping and Query:
1. Click Multicast, IGMP Snooping, General.
2. Adjust the IGMP settings as required.
3. Click Apply.

Specifying Static
Interfaces for a
Multicast Router
Use the Multicast > IGMP Snooping > Multicast Router (Add Static Multicast Router)
page to statically attach an interface to a multicast router/switch.
Depending on network connections, IGMP snooping may not always be able to
locate the IGMP querier. Therefore, if the IGMP querier is a known multicast router/
switch connected over the network to an interface (port or trunk) on the switch, the
interface (and a specified VLAN) can be manually configured to join all the current
multicast groups supported by the attached router. This can ensure that multicast
traffic is passed to all the appropriate interfaces within the switch.
