Is the same interval for sending General Query messages required on S series switches

The interval for sending General Query messages is an important parameter used to calculate the aging time of multicast forwarding entries. When configuring this parameter on a multicast network, you are advised to configure the same value on all the devices. If multicast devices use different intervals, valid multicast forwarding entries may be aged out incorrectly, causing multicast traffic interruption.
Devices from different vendors use different default intervals. When a network has devices from different vendors, configure the same interval on these devices. The default interval on S series switches is as follows:
- IGMP: 60s on S series switches and E600 fixed switches
- IGMP snooping: 60s on S series modular switches and 125s on S series and E600 fixed switches
- MLD: 125s on S series switches and E600 fixed switches
- MLD snooping: 60s on S series modular switches and 125s on S series and E600 fixed switches
