NET.CFG Options Reference

Link Support Option

Default

For IPX:

 

communication_number: The IPX protocol utilizes its

 

own buffers and does not require the Link Support

 

Layer software to provide buffers for it.

 

buffer_size: 1500 bytes

 

For TCP/IP:

 

communication_number: 8 buffers

 

buffer_size: 1500 bytes

 

TCP/IP requires only 1500 bytes, because the LAN

 

driver places the 14 bytes of media header on the

 

frame, prior to transmission.

 

For LSL:

 

buffer_size: 1514 bytes

 

This accommodates any protocol that utilizes raw

 

sends on Ethernet.

 

 

Example

To ensure that the communication buffers are large enough

 

to hold all media headers, you could place the following

 

lines in your NET.CFG file:

 

[For an Ethernet configuration]

 

link support

 

buffers 8 1514

 

[For a token-ring configuration]

 

link support

 

buffers 8 4222
