Selecting Software or Hardware Compression

When you configure a VC for compression, the default compression type varies

(Table 3-4

You can use software compression with a hardware compression daughterboard or

net module. Bay Networks recommends that you use hardware compression for

connections operating at speeds greater than 512 Kb/s. You should specify

software compression for VCs in excess of the number of contexts your hardware

compression daughterboard or net module can support.

Using the BCC

To specify hardware or software compression for a line or circuit, navigate to the

appropriate prompt (for example,

box

;

serial 3/1

;

ppp

;

wcp

), and enter:

engine-type <

type

type is hardware or software.

For example:

box#

serial 3/1

serial/3/1#

ppp

ppp/3/1#

wcp

wcp/3/1#

engine-type software

wcp/3/1#
