IGMP settings on S series switch

When multiple switches connect to the same subnet, the requirements on IGMP settings on interfaces are as follows:
Ensure that IGMP parameters configured on the interfaces on the same subnet are consistent.
These IGMP parameters affect each other. If IGMP parameters configured on the interfaces on a subnet are inconsistent, the IGMP member relationships are unordered.
Checking method: Run the display igmp interface interface-type interface-number verbose command on all the devices on a subnet to check IGMP parameters. If the IGMP parameter configurations are inconsistent, modify the configurations. IGMP parameters:
- IGMP version
- Robustness
- Query interval
- Other querier timeout
- Maximum query response time
- Last member query count
- Last member query interval
- Startup query interval
- Startup query count
