Managed Switch CLI Manual, Release 8.0 Term MAC Address Type Description Interfaces Definition A multicast MAC address for which the switch has forwarding or filtering information. The format is two-digit hexadecimal numbers that are separated by colons, for example 33:33:45:67:89:AB. In an IVL system, the MAC address is displayed as a MAC address and a VLAN ID combination of 8 bytes. The type of entry, which is either static (added by the user) or dynamic (added to the table as a result of a learning process or protocol.) The text description of this multicast table entry. The list of interfaces that are designated for forwarding (Fwd:) and filtering (Flt:). MLD Snooping Querier Commands In an IPv6 environment, MLD Snooping requires that one central switch or router periodically query all end-devices on the network to announce their multicast memberships. This central device is the MLD Querier. The MLD query responses, known as MLD reports, keep the switch updated with the current multicast group membership on a port-by-port basis. If the switch does not receive updated membership information in a timely fashion, it will stop forwarding multicasts to the port where the end device is located. This section describes the commands you use to configure and display information on MLD Snooping queries on the network and, separately, on VLANs. set mld querier Use this command to enable MLD Snooping Querier on the system (Global Config Mode) or on a VLAN. Using this command, you can specify the IP address that the snooping querier switch should use as a source address while generating periodic queries. If a VLAN has MLD Snooping Querier enabled and MLD Snooping is operationally disabled on it, MLD Snooping Querier functionality is disabled on that VLAN. MLD Snooping functionality is re-enabled if MLD Snooping is operational on the VLAN. The MLD Snooping Querier sends periodic general queries on the VLAN to solicit membership reports.
