NETGEAR M4350-24F4V 24-Port 10G SFP+ Managed AV Network Switch - Manual (Page 522)

- 1: If no switch stack is configured, the physical interfaces for the switch are
displayed.
- Unit ID for a stacked switch: If a switch stack is configured, the physical
interfaces for the switch with the selected stack unit ID are displayed.
• VLANS: Only VLANs are displayed.
• All: Both physical interfaces and VLANs are displayed, or for a switch stack, both
physical interfaces on all switches and VLANs are displayed.
7. Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the interface,
or type the interface number in the Go To Interface field and click the Go button.
• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
• To configure all interfaces with the same settings, select the check box in the
heading row.
8. In the TTL Threshold field, specify the threshold below which a multicast data packet
is not forwarded from the interface.
Enter a number between 0 and 255. The default is 1. For a packet to be forwarded,
its multicast time-to-live (TTL) value must be greater than the value that you set. If
you enter 0, all multicast packets on the interface are forwarded.
9. Click the Apply button.
Your settings are saved.
10. To save the settings to the running configuration, click the Save icon.
Distance Vector Multicast Routing
Protocol
The Distance Vector Multicast Routing Protocol (DVMRP) is used for multicasting over
IP networks without routing protocols to support multicast. The DVMRP is based on the
RIP protocol but more complex than RIP.
The DVMRP operates as follows:
1. The first message (such as an IGMP message) for any source-group pair is forwarded
to the entire multicast network, with respect to the time-to-live (TTL) of the packet.
2. TTL restricts the area to be flooded by the message.
3. All the leaf routers that do not include members on directly attached subnetworks
send back prune messages to the upstream router.
