1457prefix-length: Prefix length of the specified multicast source or multicast group.For a multicast source address, this argument has an effective value range of 0 to128; for a multicast group address, it has an effective value range of 8 to 128. Thesystem default is 128 in both cases.Description Use the reset mld group command to clear MLD forwarding entries.Note that:■ When you clear MLD forwarding entries on a VLAN interface, the MLDSnooping forwarding entries for this VLAN interface will also be cleared.■ You cannot use this command to clear MLD forwarding entries for static joins.Related command: display mld group.Example # Clear all MLD forwarding entries on all interfaces. reset mld group all# Clear all MLD forwarding entries on Ethernet 1/0. reset mld group interface ethernet 1/0 all# Clear all MLD forwarding entries for the IPv6 multicast group FF03::101:10 onEthernet 1/0. reset mld group interface ethernet 1/0 ff03::101:10# Clear all MLD forwarding entries for IPv6 multicast groups in theFF03::101:0/112 range on Ethernet 1/0. reset mld group interface ethernet 1/0 ff03::101:10 112robust-count (MLD view)Syntax robust-count robust-valueundo robust-countView MLD viewParameter robust-value: MLD querier robustness variable, with an effective range of 2 to 5.The MLD robustness variable determines the number of general queries the MLDquerier sends on startup and the number of MLD group-specific queries the MLDquerier sends upon receiving an MLD done message.Description Use the robust-count command to configure the MLD querier robustnessvariable globally.Use the undo robust-count command to restore the system default.
