Subsystem
For systems running G-series and H-series RVUs, the X25AM I/O processes (one for
each X25AM line) are configured and started by using SCF commands to the WAN
subsystem; the WAN subsystem provides the functions that COUP and SYSGEN
provided on the systems running on D-series RVUs. Specifically, the WAN subsystem
allows you to:
•
Configure X25AM I/O processes with the modifiers that affect their operation
•
Start, stop, alter, or delete X25AM I/O processes
•
Monitor the X25AM I/O processes and restart them if both the primary and backup
processes fail
You use SCF commands to the WAN subsystem to perform these functions. These
functions are persistent, even after a system restart because the WAN subsystem
stores changes, additions, and deletions in the system-configuration database.
