The ZCOM Mux subsystem can be set for auto-start upon system reboot by setting the START_ZCOM variable in file /etc/rc.config.d/acc to 1. The x25init utility can be set to auto-start upon system reboot by setting the X25INIT-FILE variable in the /etc/rc.config.d/acc file. (The x25init utility is used to bring up X.25 Level 2 connections using an x25init configuration file that describes that connection.)

NOTE: When the X.25/9000 product is used with a PSI card, x25init can be run at boot-up time by setting the X25_ARGS variable in the /etc/rc.config.d/x25 file. When the X.25/ACC product is used, however, this cannot be done; x25init can only be run after zmasterd is used to bring up the ZCOM Mux subsystem.

To set up for automatic start-up upon system boot-up, do the following:

  1. Set the START_ZCOM variable to 1 in /etc/rc.config.d/acc. This will cause zmasterd to start the ZCOM Mux subsystem upon reboot, using the ttgen configuration file specified in step 2.

  2. Set the TMEM variable in /etc/rc.config.d/acc to the name of your chosen .tmem file (which is the output of running ttgen on a .answ configuration file).

    NOTE: If this variable is NOT set, the one specified in /opt/acc/cfg/zmasterd_list will be used by default.
  3. Set the X25INIT_FILE variable in /etc/rc.config.d/acc to be the full pathname of a script file to contain the x25init requests.

Following is an example of a script file:

#!/usr/bin/ksh
/usr/sbin/x25init -c /etc/x25/00looptest \
-a /etc/x25/loop_ipmap >>/tmp/x25init_all.log 2>&1
/usr/sbin/x25init -c /etc/x25/01looptest \
-a /etc/x25/loop_ipmap >> /tmp/x25init_all.log 2>&1

When these three variables are set as described, zmasterd automatically starts the ZCOM Mux subsystem, and the x25init utility brings up the X.25 Level 2 connections at system boot-up.
