Configuration Guide Configuring IGMP Snooping
Configuration Steps
Enabling the Querier Function
(Optional) Enable IGMP querier function globally or for a specified VLAN.
(Optional) Disable the IGMP querier function for a specified VLAN.
Configuring the Source IP Address of a Querier
(Optional) You can configure the source IP address of a Query packet sent by the querier based on VLANs.
After a querier is enabled, a source IP address must be specified for the querier; otherwise, the configuration will not
take effect.
Configuring the Maximum Response Time of a Query Packet
(Optional) Adjust the maximum response time carried by an IGMP Query packet. As IGMPv1 does not support the
carrying of maximum response time by a Query packet, this configuration does not take effect when the querier is
running IGMPv1.
Configuring the Query Interval of a Querier
(Optional) Adjust the interval of the IGMP querier for sending query packets.
Configuring the Aging Timer of a Querier
(Optional) Configure the aging timer of other IGMP queriers on the network.
Specifying the IGMP Version for a Querier
(Optional) Specify the IGMP version for a querier (IGMPv2 by default).
Verification
Run the show ip igmp snooping querier detail command to check whether the configuration takes effect.
