CHAPTER 3
WEB OPERATION & CONFIGURATION
Source Address:
The source IP address available for filtering.
Type:
Display either Allow or Deny type.
Hardware Filter/Switch:
Indicates whether the data plane destined to the specific group address from the source IPv4
address can be handled by the chip or not.
3.11.2 MLD Snooping
Multicast Listener Discovery (MLD) snooping, similar to IGMP snooping for IPv4, operates on IPv6 for multicast traffic.
In other words, MLD snooping configures ports to limit or control IPv6 multicast traffic so that multicast traffic is
forwarded to ports (or users) who want to receive it. In this way, MLD snooping can reduce the flooding of IPV6
multicast packets in the specified VLANs. Please note that IGMP Snooping and MLD Snooping are independent of each
other. They can both be enabled and function at the same time.
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.
