Limiting LAN Traffic to One Network Adapter

MORE INFORMATION

The example below assumes two network adapters, one ethernet and one Token Ring. The ethernet adapter is configured for NetBIOS over TCP/IP and the Token Ring adapter is configured for DLC, NetBEUI, IPX/SPX and NetBIOS over TCP/IP.

The objective is to limit LAN traffic on the upstream DLC connection to the host by disabling selected bindings on the Token Ring adapter. The steps necessary to perform this operation are outlined below:

1. Show Bindings for All Components in the Network Bindings Dialog Box.
2. Disable the following bindings:

         NetBIOS Interface --> WINS Client (TCP/IP) -->
         IBM Token Ring Adapter Driver --> (2) IBM Token Ring 4/16 Adapter
   
         NetBIOS Interface --> NetBEUI Protocol  -->
         IBM Token Ring Adapter Driver --> (2) IBM Token Ring 4/16 Adapter
   
         Server --> WINS Client (TCP/IP) --> IBM Token Ring Adapter Driver -->
         (2) IBM Token 4/16 Adapter
   
         Server -->  NetBEUI Protocol --> IBM Token Ring Adapter Driver -->
         (2) IBM Token Ring 4/16 Adapter
   
         Workstation --> WINS Client (TCP/IP) -->
         IBM Token Ring Adapter Driver --> (2) IBM TokenRing 4/16 Adapter
   
         Workstation --> NetBEUI Protocol -->
         IBM Token Ring Adapter Driver --> (2) IBM Token Ring 4/16 Adapter
   
         NWLink IPX/SPX Compatible Transport -->
         IBM Token Ring Adapter Driver --> (2) IBM TokenRing 4/16 Adapter
   					

3. Accept changes and restart the server.

NOTE: It is not necessary to disable SNA Server Link service or DLC transport bindings because the SNA Server DLC 802.2 link service only communicates over the adapter specified during SNA Server Setup. There is no traffic generated by the SNA Server link service over the unused DLC card binding.
