Netbios Rebroadcast; Configuring The Arp Table - Avaya G250 Administration

NetBIOS rebroadcast

Network Basic Input Output System (NetBIOS) is a protocol for sharing resources among
desktop computers on a LAN. You can configure the Avaya G250/G350 Media Gateway to relay
NetBIOS UDP broadcast packets. This feature is used for applications such as WINS that use
broadcast but might need to communicate with stations on other subnetworks or VLANs.
Configuration is performed on a per-interface basis. A NetBIOS broadcast packet arrives from
an interface on which NetBIOS rebroadcast is enabled. The packet is distributed to all other
interfaces configured to rebroadcast NetBIOS.
If the NetBIOS packet is a net-directed broadcast, for example, 149.49.255.255, the packet is
relayed to all other interfaces on the list, and the IP destination of the packet is replaced by the
appropriate interface broadcast address.
If the NetBIOS broadcast packet is a limited broadcast, for example, 255.255.255.255, it is
relayed to all VLANs on which there are NetBIOS-enabled interfaces. In that case, the
destination IP address remains the limited broadcast address.
Use the ip netbios-rebroadcast both command to enable NetBIOS rebroadcasts on an
interface. Use the ip netbios-rebroadcast disable command to disable NetBIOS
rebroadcasts on an interface.
