Configuring a Port for a Dedicated Connection
5-24 PortMaster Configuration Guide
The PortMaster supports Stac LZS data compression only for PPP connections with
bidirectional compression. Stac LZS data compression cannot be used for SLIP
connections.
To configure compression, use the following command:
Command> set S0|W1 compression on | stac | vj | off
Table 5-4 describes the results of using each keyword.
Note – This command is used only on network hardwired asynchronous ports. Dial-in
users must use the user table or RADIUS instead. Dial-out locations must use the
location table instead.
To display compression information about a connection, enter the following command:
Command> show S0
Setting the PPP Asynchronous Map
The PPP protocol supports the replacement of nonprinting ASCII characters found in the
datastream. These characters are not sent through the connection but are instead
replaced by a special set of characters that the remote system interprets as the original
Table 5-4 Keywords for Configuring Compression
Keyword Description
on Enables compression. The PortMaster tries to negotiate both
Van Jacobson and Stac LZS compression on PortMaster 3 and
on leased lines on Office Router products, or Van Jacobson
compression only on other PortMaster products. This is the
default.
off Disables compression.
stac Enables Stac LZS data compression only. Stac LZS
compression is supported only on PortMaster 3 and leased
lines on Office Router products.
vj Enables Van Jacobson TCP/IP header compression only.
