Disabling Software Modules

Model 5399 Remote Access Concentrator Network Administrator's Guide for UNIX
The 5399 RAC parameter disabled_modules allows you to disable
individual software modules to free memory space. If you enter more than
one module, separate module names using commas. Valid options are
admin, atalk, dialout, edit, fingerd, ftpd, ipx, lat, nameserver, ppp,
slip, snmp, tn3270, tstty, vci, all, or none. The default is vci (disables
the 5399 RAC VMS interface).
The syntax for disabling several modules is:
set annex disabled_modules lat,snmp,ppp,slip
You should exercise extreme caution when disabling modules:
• If disabled_modules is set to a value other than none and
server_capability includes the operational image, no
modules are disabled; a syslog message announces this
override.
• The vci option disables the 5399 RAC interface for VMS
environments along with the following commands:
backwards, change, clear, crash, define, disconnect,
forwardlis, forward, list, logout, resume, set, show.
• If lat_key is invalid and server_capability is set to none, the
LAT code is freed for use by the system.
• Disabling LAT also disables the CLI commands services,
connect, and queue.
• Disabling admin and snmp can cause problems if host-based
na is not available. To change parameters in this case, return
to monitor mode, erase the parameters in non-volatile
memory, and reconfigure the 5399 RAC.
