Specifying A Permanent Sdr Configuration File With The Iox_Config_File= Variable - Cisco ASR 9000 Series Configuration Manual

Specifying a Permanent SDR Configuration File with the IOX_CONFIG_FILE= Variable

Specifying a Permanent SDR Configuration File with the IOX_CONFIG_FILE=
Variable
This mode of alternative SDR configuration with the IOX_CONFIG_FILE= variable is permanent in nature.
Once this variable is set, this mode allows the router to always boot from this alternative configuration. The
system does not revert to the default commited configuration on the next system reload.
Note When the router boots with the external configuration specified by the IOX_CONFIG_FILE= variable,
the system loses the default configuration. The default configuration is completely replaced with this
alternative configuration.
To permanently change the location of the default configuration file for an SDR, specify the filename and
directory path in the IOX_CONFIG_FILE= environment variable while in ROM Monitor mode. Specifying
the environment variable forces the use of the specified file for all boots while this variable is set.
