The purpose of multicast filtering is to optimize a switched network’s
performance, so multicast packets will only be forwarded to those ports
containing multicast group hosts or multicast routers/switches, instead of
flooding traffic to all ports in the subnet.
You can enable IGMP Snooping and Query via the Switch Settings menu,
and display information about multicast traffic being forwarded by the
switch via the Filtering Database menu as shown below.
Field Attributes
• Enable IGMP Protocol
– When enabled, the switch will monitor
network traffic to determine which hosts want to receive multicast
traffic. This is also referred to as IGMP Snooping. (Default: Enabled)
• IGMP Query Mode
– When enabled (or selected as the Querier
through auto-negotiation), the switch will serve as the local Querier,
which is responsible for asking hosts if they want to receive multicast
traffic. This is also referred to as IGMP Query. Note that using the Auto
option generates less protocol traffic compared to the Enable option.
(Options: Auto, Enable, Disable; Default: Auto)
•
IP Address
– Multicast service addresses (224.0.0.0 - 239.255.255.255).
•
VID
– ID of configured VLAN (1-4094). This field is only displayed if
IEEE 802.1Q tagged VLANs are enabled (page 3-29).
•
Member Port
– Ports receiving a specific multicast service.
Web
– Click Administrator=>Switch Settings=>Advanced. Enable IGMP
Protocol, set the IGMP Query Mode to the required option, and click
Apply.
