GS700TS Smart Switch Software Administration Manual Multicast Multicast forwarding allows a single packet to be forwarded to multiple destinations. L2 Multicast service is based on L2 switch receiving a single packet addressed to a specific Multicast address. Multicast forwarding creates copies of the packet, and transmits the packets to the relevant ports. • Registered Multicast traffic - If traffic addressed to a registered Multicast group is seen it is handled by an entry in the Multicast Filtering Database and forwarded only to the registered ports. • Unregistered Multicast traffic - If traffic addressed to an unregistered Multicast group is seen it is handled by a special entry in the Multicast Filtering Database. The default setting of this is to flood all such traffic (traffic in unregistered Multicast groups). Layer 2 switching forwards Multicast packets to all relevant VLAN ports by default, treating the packet as a Multicast transmission. Multicast traffic forwarding is functional. However, irrelevant ports also receive the Multicast, causing increased network traffic. Multicast forwarding filters enable forwarding of Layer 2 packets to port subsets, defined in the Multicast filter database. The device supports forwarding L2 Multicast Packets. Multicast forwarding is enabled by default, and not configurable by user. The Multicast menu contains the following options: • "Basic" • "Advanced" Basic The Multicast Basic menu contains the following options: • "IGMP Snooping Configuration" IGMP Snooping Configuration The IGMP Snooping Configuration screen contains information for enabling and defining IGMP Snooping on the device. When IGMP snooping is enabled, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines which ports to join which Multicast groups, which ports have Multicast routers generating IGMP queries, and what routing protocols are forwarding packets and Multicast traffic. A port requesting to join a specific Multicast group issues an IGMP report specifying that Multicast group. This results in the creation of the Multicast filtering database. 4-43 v1.0, June 2009 Configuring Switching Settings

Multicast

Multicast forwarding allows a single packet to be forwarded to multiple destinations. L2 Multicast

service is based on L2 switch receiving a single packet addressed to a specific Multicast address.

Multicast forwarding creates copies of the packet, and transmits the packets to the relevant ports.

•

Registered Multicast traffic

– If traffic addressed to a registered Multicast group is seen it is

handled by an entry in the Multicast Filtering Database and forwarded only to the registered

ports.

•

Unregistered Multicast traffic

– If traffic addressed to an unregistered Multicast group is

seen it is handled by a special entry in the Multicast Filtering Database. The default setting of

this is to flood all such traffic (traffic in unregistered Multicast groups).

Layer 2 switching forwards Multicast packets to all relevant VLAN ports by default, treating the

packet as a Multicast transmission. Multicast traffic forwarding is functional. However, irrelevant

ports also receive the Multicast, causing increased network traffic. Multicast forwarding filters

enable forwarding of Layer 2 packets to port subsets, defined in the Multicast filter database.

The device supports forwarding L2 Multicast Packets. Multicast forwarding is enabled by default,

and not configurable by user.

IGMP Snooping Configuration

The IGMP Snooping Configuration screen contains information for enabling and defining IGMP

Snooping on the device. When IGMP snooping is enabled, all IGMP packets are forwarded to the

CPU. The CPU analyzes the incoming packets and determines which ports to join which Multicast

groups, which ports have Multicast routers generating IGMP queries, and what routing protocols

are forwarding packets and Multicast traffic. A port requesting to join a specific Multicast group

issues an IGMP report specifying that Multicast group. This results in the creation of the Multicast

filtering database.
