H3C IE4300 Command Reference Manual page 1529

You can set the timer for a VLAN in VLAN view or globally for all VLANs in IGMP-snooping view. For
a VLAN, the VLAN-specific configuration takes priority over the global configuration.
To avoid mistakenly deleting multicast group members, set the aging timer for dynamic member
ports to be greater than the value calculated by using the following formula:
IGMP general query interval
[
As a best practice, set the aging timer of dynamic member ports to the value calculated by using the
following formula:
[ IGMP general query interval
Examples
# In VLAN 2, enable IGMP snooping, and set the aging timer for dynamic member ports to 300
seconds.
