  • Page 63: Mld-Snooping Query-Interval

    Parameters None Description Use the mld-snooping querier command to enable the MLD snooping querier function. Use the undo mld-snooping querier command to disable the MLD snooping querier function. By default, the MLD snooping querier function is disabled. This command takes effect only if MLD snooping is enabled for the VLAN. It does not take effect in a sub- VLAN of an IPv6 multicast VLAN.
