Configuring Dial-Out Connections 8-9
Configuring the Location Table
Compression cannot be used with multiline load-balancing, but can be used with
Multilink PPP.
Compression must be enabled on both ends of the connection if you are using SLIP.
With SLIP, TCP packets are not passed if only one side of the connection has
compression enabled. For PPP connections, the PortMaster supports both bidirectional
and unidirectional compression. Refer to RFC 1144 for more information about header
compression.
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 for a location, use the following command:
Command> set location Locname compression on|off|stac|vj
Table 8-3 describes the results of using each keyword.
To display compression information about a location, enter the following command:
Command> show S0

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 the PortMaster 3 and on leased lines on Office
Router products.
vj Enables Van Jacobson TCP/IP header compression only.
