CHAPTER 4
WEB OPERATION & CONFIGURATION
4.3.11.2.1 Basic Configuration
Global Configuration
Snooping Enabled:
Select the checkbox to globally enable MLD Snooping feature. When enabled, this device will
monitor network traffic and determine which hosts would like to receive multicast traffic. The switch can passively
monitor or snoop on MLD Listener Query and Report packets transferred between IP multicast routers and IP
multicast service subscribers to identify the multicast group members. The switch simply monitors the IGMP packets
passing through it, picks out the group registration information and configures the multicast filters accordingly.
Unregistered IPMCv6 Flooding Enabled:
Set forwarding mode for unregistered (not-joined) IP multicast traffic. Select
the checkbox to flood traffic.
MLD SSM Range:
SSM (Source-Specific Multicast) Range allows the SSM-aware hosts and routers run the SSM service
model for the groups in the address range.
Leave Proxy Enabled:
To prevent multicast router from becoming overloaded with leave messages, MLD snooping
suppresses leave messages unless received from the last member port in the group. When the switch acts as the
querier, the leave proxy feature will not function.
Proxy Enabled:
When MLD proxy is enabled, the switch exchanges MLD messages with the router on its upstream
interface, and performs the host portion of the MLD task on the upstream interface as follows:
When queried, it sends multicast listener reports to the group.
When a host joins a multicast group to which no other host belongs, it sends unsolicited multicast listener
reports to that group.
When the last host in a particular multicast group leaves, it sends an unsolicited multicast listener done
report to the all-routers address (FF02::2) for MLDv1.
Port Related Configuration
Port:
The port number.
Router Port:
Tick the checkbox on a given port to assign it as a router port. If MLD snooping cannot locate the MLD
querier, you can manually designate a port which is connected to a known MLD querier (i.e., a multicast
router/switch). This interface will then join all the current multicast groups supported by the attached router/switch
