H3C IE4300 Command Reference Manual page 1606

To avoid mistakenly deleting IPv6 multicast group members, set the aging timer for dynamic member
ports to be greater than the value calculated by using the following formula:
MLD general query interval
[
As a best practice, set the aging timer of dynamic member ports to the value calculated by using the
following formula:
MLD general query interval
[
Examples
# In VLAN 2, enable MLD snooping, and set the aging timer for dynamic member ports in the VLAN
to 300 seconds.
