System Administration Guide: Advanced Administration

Using the Service Access Facility

You can set up terminals and modems with the Solaris Management Console's Serial Ports tool or the SAF commands.

The SAF is a tool that is used to administer terminals, modems, and other network devices. The top-level SAF program is the Service Access Controller (SAC). The SAC controls port monitors that you administer through the sacadm command. Each port monitor can manage one or more ports.

You administer the services associated with ports through the pmadm command. While services provided through the SAC can differ from network to network, the SAC and its administrative commands, sacadm and pmadm, are network independent.

The following table describes the SAF control hierarchy. The sacadm command is used to administer the SAC, which controls the ttymon and listen port monitors.

The services of ttymon and listen are in turn controlled by the pmadm command. One instance of ttymon can service multiple ports. One instance of listen can provide multiple services on a network interface.

Table 3–1 SAF Control Hierarchy


Function	Program	Description
Overall administration	`sacadm`	Command for adding and removing port monitors
Service Access Controller	`sac`	SAF's master program
Port monitors	`ttymon` `listen`	Monitors serial port login requests Monitors requests for network services
Port monitor service administrator	`pmadm`	Command for controlling port monitors services
Services	logins, remote procedure calls	Services to which the SAF provides access
Console administration	console login	Console services are managed by the SMF service, `svc:/system/console-login:default`. This service invokes the `ttymon` port monitor. Do not use the `pmadm` or the `sacadm` command to manage the console. For more information, see `ttymon` and the Console Port, How to Set the `ttymon` Console Terminal Type, and How to Set the Baud Rate Speed on the `ttymon` Console Terminal.
