CONFIGURING THE SWITCH

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.
