Typical trunk port clock source configurations

The following sample commands configure both ports of the a DS3-ATM module as
eligible clock sources, with the first port assigned a higher priority for this use:
admin> read ds3-atm { 1 trunk-module-2 1 }
DS3-ATM/{ shelf-1 trunk-module-1 1 } read
admin> set line-config clock-source = eligible
admin> set line-config clock-priority = high
admin> write
DS3-ATM/{ shelf-1 trunk-module-2 1 } written
admin> read ds3-atm { 1 trunk-module-2 2 }
DS3-ATM/{ shelf-1 trunk-module-1 2 } read
admin> set line-config clock-source = eligible
admin> set line-config clock-priority = low
admin> write
DS3-ATM/{ shelf-1 trunk-module-2 2 } written
Additional information about configuring OC3-ATM and DS3-ATM trunk modules
can be found in the chapter dealing with the desired module.
Retaining basic configuration settings for remote
administration
In TAOS 9.2-167 and later, you can store minimal system configuration information
in a file called default.cfg to enable the system to start up with some configuration
information, even after you issue the nvram command. This feature enables setups
with requirements for inband management to clear nonvolatile RAM (NVRAM) and
restart the Stinger MRT unit with a minimal configuration, such as the Ethernet
configuration and some ATM connection configurations, so that inband management
can proceed.
You can save a minimal configuration to the default.cfg file in a directory of flash
memory. After you issue the nvram command, the unit reboots and checks NVRAM
for configuration information.
The system searches for a default.cfg file in the flash directory /directory, then in
directory/current.
If the system finds a default.cfg file, it loads the saved configuration to NVRAM and
restarts with the minimal configuration information from the default.cfg file. If you
save more than one default.cfg file in the flash directories, the software processes
the first default.cfg file that it finds based on the order listed in the preceding
section. If the system finds no default.cfg file, then no configuration file is loaded
from flash and the system restarts without any configuration, as in previous software
releases.

Storing a partial configuration for restart after clearing NVRAM

To enable a Stinger MRT unit to start up with some minimal configuration
information after you have issued the nvram command, you must create a
