DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is only available for VLAN interface configuration. If the system can play the querier role, the entity will listen for IGMP query packets sent by other devices.

Switch# configure terminal Switch(config)# vlan 1 Switch(config-vlan)# ip igmp snooping querier Switch(config-vlan)# 32-8 ip igmp snooping query-interval This command is used to configure the interval at which the IGMP snooping querier sends IGMP general query messages periodically. Use the no form of the command to revert to the default setting. ip igmp snooping query-interval SECONDS no ip igmp snooping query-interval Parameters SECONDS Specifies to configure the interval at which the designated router sends IGMP general-query messages.

Usage Guideline This command is only available for VLAN interface configuration. The query interval is the interval between General Queries sent by the Querier. By varying the query interval, an administrator may tune the number of IGMP messages on the network; larger values cause IGMP Queries to be sent less often.
