Specifying A Temporary Sdr Configuration File With The -A Boot Option - Cisco ASR 9000 Series Configuration Manual

Managing Configuration Files in ROM Monitor
The default committed SDR configuration should be sufficient for most situations. The option described
Caution
in this section is for rare cases when an alternative SDR configuration is required. Use of this method can
result in system errors or downtime.

Specifying a Temporary SDR Configuration File with the -a Boot Option

This mode of SDR configuration with the -a boot option is temporary in nature. Once this boot option is set,
this mode allows the router to boot from this alternative configuration and the configuration specified in this
configuration file becomes part of the running and persistent configuration.
Note When the router boots with the external configuration specified by the -a option, the system loses the
default configuration. The default configuration is completely replaced with this alternative configuration.
To specify a temporary SDR configuration file with the -a boot option, use the following procedure. With
this method, the specified configuration file is used for a single router boot. If the DSC is reset again, the
permanent configuration file is used.
