MLD
MLD
(Multicast Listener Discovery)
snooping enables a controller, service platform or access point to examine MLD packets
and make forwarding decisions based on content. MLD is used by IPv6 devices to discover
devices wanting to receive multicast packets destined for specific multicast addresses. MLD
uses multicast listener queries and multicast listener reports to identify which multicast
addresses have listeners and join multicast groups.
MLD snooping caps
the flooding of IPv6 multicast traffic on controller, service platform or access point
VLANs. When enabled, MLD messages are examined between hosts and multicast routers and to
discern which hosts are receiving multicast group traffic. The controller, service platform
or access point then forwards multicast traffic only to those interfaces connected to
interested receivers instead of flooding traffic to all interfaces.
To view network MLD statistics:
- Select the Statistics menu from the Web UI.
- Expand the System
node from the navigation pane (on the left-hand side of the screen). The
System node expands to display the RF Domains created within the managed network.
- Expand the RF Domain
node.
- Select a Wireless
Controller.
- Expand the Network
menu from the left-hand side of the UI.
- Select MLD.
The stats is displayed in the right-hand pane.
The
Multicast Listener Discovery (MLD) Group field describes the
following:
VLAN |
Displays the group VLAN where the MLD groups
multicast transmission is conducted. |
Group Address |
Displays the Multicast Group ID supporting the
statistics displayed. This group ID is the multicast address hosts are
listening to. |
Port Members |
Displays the ports on which MLD multicast clients
have been discovered. For example, ge1, radio1, etc. Ports can vary somewhat
amongst supported controller and service platform models. |
Version |
Displays each listed group‘s version compatibility
as either version 1, 2 or 3. |
|
The
IPv6 Multicast Router (MRouter) field describes the following:
VLAN |
Displays the group VLAN where the multicast
transmission is conducted. |
MINT IDs |
Lists MiNT IDs for each listed VLAN. MiNT provides
the means to secure communications at the transport layer. Using MiNT, a
controller or service platform can be configured to only communicate with
other authorized (MiNT enabled) devices. |
Learn Mode |
Displays the learning mode used by the router as
either Static or PIM-DVMRP. |
Port Members |
Displays the physical ports on which multicast
clients have been discovered by the multicast router. For example, ge1,
radio1, etc. Ports can vary somewhat amongst supported controller and service
platform models. |
Query Interval |
Lists the query interval implemented when the
querier functionality is enabled. The default value is 60 seconds. |
Version |
Lists the multicast router version compatibility
as either version 1, 2 or 3. The default setting is 3. |
