Enabling or Disabling MLD Snooping
By default, IPv6 MLD snooping is globally disabled on the switch and enabled on all VLANs. When MLD snooping is
globally disabled, it is also disabled on all VLANs. When you globally enable MLD snooping, the VLAN configuration
overrides the global configuration. That is, MLD snooping is enabled only on VLAN interfaces in the default state
(enabled).
