Usage guidelines

You can set the timer globally for all VLANs and VSIs in MLD-snooping view, for a VSI in VSI view, or for a VLAN in VLAN view. For a VSI, the VSI-specific configuration takes priority over the global configuration. For a VLAN, the VLAN-specific configuration takes priority over the global configuration.

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 ] + [ maximum response time for MLD general queries ]

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 ] × 2 + [ maximum response time for MLD general queries ]

Examples

# Set the global aging timer for dynamic member ports to 300 seconds.

<Sysname> system-view
[Sysname] mld-snooping
[Sysname-mld-snooping] host-aging-time 300
