Parameter: Buffer Size

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.

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

connection.

Instructions: 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

Note: 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.

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. You can use hardware compression with Frame Relay and PPP

only. You can use software compression with Frame Relay, PPP, or X.25.

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

hardware-based compression.
