WEB OPERATION & CONFIGURATION
of multicast traffic reduces the packet processing at the switch (at the cost of needing additional memory to handle
the multicast tables) and also decreases the workload at the end hosts since their network cards (or operating system)
will not receive and filter all the multicast traffic generated in the network.
4.3.11.1.1 Basic Configuration
Global Configuration
Snooping Enabled:
Select the checkbox to globally enable IGMP Snooping feature. When enabled, this device will
monitor network traffic and determine which hosts will receive multicast traffic. The switch can passively monitor or
snoop on IGMP 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 IPMCv4 Flooding Enabled:
Set forwarding mode for unregistered (not-joined) IP multicast traffic. Select
the checkbox to flood traffic.
IGMP 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:
Suppresses leave messages unless received from the last member port in the group. IGMP leave
proxy suppresses all unnecessary IGMP leave messages so that a non-querier switch forwards an IGMP leave packet
only when the last dynamic member port leaves a multicast group.
Proxy Enabled:
When enabled, the switch performs like “IGMP Snooping with Proxy Reporting” (as defined in DSL
Forum TR-101, April 2006).
Port Related Configuration
Port:
The port number.
Router Port:
Tick the checkbox on a given port to assign it as a router port. If IGMP snooping cannot locate the IGMP
