Parameter: Buffer Size

Because X.25 has features that check for errors and prevent data loss, Bay Networks data compression software

ignores the Buffer Size parameter for X.25. If you are configuring compression for X.25, you do not have to set this

parameter.

Path: Configuration Manager > Protocols > WCP > Lines

Default: Normal

Options: Very Large

Large

Normal

None

Function: Indicates the amount of buffer memory for the transmission history on a line.

Instructions: Set this parameter according to the end-to-end round-trip length of a WCP

connection:

Select Normal for most land-line, coast-to-coast connections.

Select Large or Very Large for connections at a great distance from each other,

such as satellite connections.

Select None for links that drop a very small number of packets.

Increase the buffer size for a link with a large number of resets.

MIB Object ID: 1.3.6.1.4.1.18.3.4.22.1.1.7

Parameter: Engine Type

Path: Configuration Manager > Protocols > WCP > Lines

Default: Software, unless you have configured either an Octal Sync link module that has

a hardware compression daughterboard for the BN, or a hardware compression

net module for the ASN, in which case the default is Hardware.

Options: Software

Hardware

Function: Determines whether compression for this node will be software- or

hardware-based.

Instructions: Select Software to use software-based compression or select Hardware to use

hardware-based compression. You can use hardware compression with PPP and

frame relay only. You can use software compression with PPP, frame relay, or

X.25.
