ProSAFE M7100 Managed Switches
When the optional argument detail is used, the command shows the global information and the
information for all Querier-enabled VLANs.
MLD Snooping Commands
This section describes commands used for MLD Snooping. In IPv4, Layer 2 switches can use IGMP
Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2 interfaces
so that multicast traffic is forwarded only to those interfaces associated with IP multicast
addresses. In IPv6, MLD Snooping performs a similar function. With MLD Snooping, IPv6
multicast data is selectively forwarded to a list of ports that want to receive the data, instead of
being flooded to all ports in a VLAN. This list is constructed by snooping IPv6 multicast control
packets.
set mld
Use this command to enable MLD Snooping on the system (Global Config Mode) or an interface
(Interface Config Mode). This command also enables MLD Snooping on a particular VLAN and
enables MLD Snooping on all interfaces participating in a VLAN.
If an interface has MLD Snooping enabled and you enable this interface for routing or enlist it as a
member of a port-channel (L
AG), MLD Snooping functionality is disabled on that interface. MLD
Snooping functionality is re-enabled if you disable routing or remove port channel (LAG)
membership from an interface that has MLD Snooping enabled.
MLD Snooping supports the following activities:
• Validation of address version, payload length consistencies and discarding of the frame upon
er
ror.
• Maintenance of the forwarding table entries based on the MAC address versus the IPv6
addr
ess.
• Flooding of unregistered multicast data packets to all ports in the VLAN.
Querier VLAN
Address
The IP address will be used in the IPv4 header while sending out IGMP queries on this VLAN. It
can be configured using the appropriate command.
Operational
Version
The v
ersion of IPv4 will be used while sending out IGMP queries on this VLAN.
Last Querier
Addres
s
Indicates the IP address of the most recent Querier from which a Query was received.
Last Querier
Version
Indicates the IGMP version of the most recent Querier from which a Query was received on
this VLAN.
