Reference Guide

This section describes commands used to configure and display information on IGMP Snooping
Queriers on the network and, separately, on VLANs.
Note
This note clarifies the prioritization of MGMD Snooping Configurations. Many of the
IGMP/MLD Snooping commands are available both in the Interface and VLAN modes.
Operationally the system chooses or prefers the VLAN configured values over the Interface
configured values for most configurations when the interface participates in the VLAN.
set igmp querier
Use this command to enable IGMP Snooping Querier on the system, using Global Config mode, or on a
VLAN. Using this command, you can specify the IP Address that the Snooping Querier switch should
use as the source address while generating periodic queries.
If a VLAN has IGMP Snooping Querier enabled and IGMP Snooping is operationally disabled on it, IGMP
Snooping Querier functionality is disabled on that VLAN. IGMP Snooping functionality is re-enabled if
IGMP Snooping is operational on the VLAN.
Note
The Querier IP Address assigned for a VLAN takes preference over global configuration.
The IGMP Snooping Querier application supports sending periodic general queries on the VLAN to
solicit membership reports.
