Netopia 3300-ENT manual Dhcp NetBIOS Options

IP Setup 6-21

Numerous factors influence the choice of served address. It is difficult to specify the address that will be served to a particular client in all circumstances. However, when the address server has been configured, and the clients involved have no prior address serving interactions, the Router will generally serve the first unused address from the first address pool with an available address. The Router starts from the pool on the first row and continues to the pool on the last row of this screen.

Once the address server and/or the clients have participated in address serving transactions, different rules apply:

•When requesting an address, a client will often suggest an address to be assigned, such as the one it was last served. The Router will attempt to honor this request if the address is available. The client stores this address in non-volatile storage, for example, on disk, and the specific storage method/location differs depending on the client operating system.

•When requesting an address, a client may provide a client identifier, or, if it does not, the Netopia Firmware Version 8.4 may construct a pseudo-client identifier for the client. When the client subsequently requests an address, the Router will attempt to serve the address previously associated with the pseudo-client identifier. This is normally the last address served to the client.

•Otherwise, the Netopia will select the least-recently used available address, starting from the first address in the first pool and ending with the last address in the last pool.

Note: The address serving pools on this screen are tied to the IP subnets configured on the IP Subnets screen. Changes to the IP Subnets screen may affect this screen. In particular, deleting a subnet on the IP Subnets screen will delete the corresponding address serving pool, if any, on this screen.

DHCP NetBIOS Options

If your network uses NetBIOS, you can enable the Router to use DHCP to distribute NetBIOS information.

NetBIOS stands for Network Basic Input/Output System. It is a layer of software originally developed by IBM and Sytek to link a network operating system with specific hardware. NetBIOS has been adopted as an industry standard. It offers LAN applications a variety of “hooks” to carry out inter-application communications and data transfer. Essentially, NetBIOS is a way for application programs to talk to the network. To run an application that works with NetBIOS, a non-IBM network operating system or network interface card must offer a NetBIOS emulator. Many vendors either provide a version of NetBIOS to interface with their hardware or emulate its transport layer communications services in their network products. A NetBIOS emulator is a program provided by NetWare clients that allow workstations to run applications that support IBM’s NetBIOS calls.
