When IGMP or MLD multicast snooping is enabled on a vSphere Distributed Switch, 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 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 Client, navigate to the host.
- On the Configure tab, expand System and select Advanced System Settings.
- Click Edit.
- Locate the Net.IGMPQueryInterval system setting and enter a new value in seconds for the setting.
- Click OK
