NetBIOS Re-broadcast Configuration
NetBIOS Overview
Short for Network Basic Input Output System, an application programming
interface (API) that augments the DOS BIOS by adding special functions for local-
area networks (LANs). Almost all LANs for PCs are based on the NetBIOS. Some
LAN manufacturers have even extended it, adding additional network capabilities.
The Avaya P330 can be configured to relay netbios UDP broadcast packets. This
feature is used for applications such as WINS that use broadcast but may need to
communicate with stations on other subnets or VLANs.
Configuration is performed on a per-interface basis. When 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 (e.g., 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 (e.g., 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.
