PPP Configurations and Terminology

This section introduces PPP configurations. The section also defines terms that are used in this guide.

Solaris PPP 4.0 supports a number of configurations.

• Switched-access, or dial-up, configurations

• Hardwired, or leased-line configurations

Figure 1-1  Parts of the PPP Link

The previous figure shows a basic PPP link. The link has the following parts:

• Two machines, usually in separate physical locations, called peers. A peer could be a personal computer, engineering workstation, large server, or even a commercial router, depending on a site's requirements.

• Serial interface on each peer. On Oracle Solaris machines, this interface could be cua, hihp, or other interface, depending on whether you configure asynchronous or synchronous PPP.

• Physical link, such as a serial cable, a modem connection, or a leased line from a network provider, such as a T1 or T3 line.
