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
