Multicast - NETGEAR GS724AT - ProSafe Gigabit Smart Switch Software Administration Manual

GS700AT Series Smart Switch Software Administration Manual
– Enable – Enable a point-to-point link, or configure to automatically establish a point-
to-point link. To establish communications over a point-to-point link, the originating
PPP first sends Link Control Protocol (LCP) packets to configure and test the data
link. After a link is established and optional facilities are negotiated as needed by the
LCP, the originating PPP sends Network Control Protocol (NCP) packets to select and
configure one or more network layer protocols. When each of the chosen network
layer protocols has been configured, packets from each network layer protocol can be
sent over the link. The link remains configured for communications until explicit LCP
or NCP packets close the link, or until some external event occurs. This is the actual
switch port link type. It may differ from the administrative state.
– Disable – Disable point-to-point link.
– Auto – Enable the device to automatically establish a point-to-point link.
• Point-to-Point Operational Status – Displays the point-to-point operating state.
• Activate Protocol Migration – Activate sending Link Control Protocol (LCP) packets to
configure and test that the data link is enabled.

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).
