When IGMP or MLD multicast snooping is enabled on a vSphere Distributed Switch 6.0, the switch sends general queries about the membership of virtual machines in case a snooping querier is not configured on the physical switch. On ESXi 6.0 hosts that are attached to the distributed switch, you can edit the time interval in which the switch sends general queries.
The default time interval for sending snooping queries is 125 seconds.
- In the vSphere Web Client, navigate to the host.
- On the Manage tab, click Settings and select Advanced System Settings.
- Locate the Net.IGMPQueryInterval system setting.
- Click Edit and enter a new value in seconds for the setting.
