Accelerating the LN Series Router Boot-Up Process
To minimize the time required for an LN Series router to become operational, you can
configure these BOOT features to accelerate the startup process:
•
Disable or enable power-on self test (POST) using the
no_run_post
environmental
variable.
•
Disable or enable file system cleanup using the
fs_clean_boot
environmental variable.
•
Remove temporary files left over from the IDP security package installation.
BEST PRACTICE:
We recommend that you only enable the
no_run_post
and
the
fs_clean_boot
environmental variables in networks when the time to boot
the platform is critical to system operations.
These options are not mutually exclusive and not linked. You can choose to
set both options, set only one option, or set neither of the options. If neither
option is set, the LN Series router’s default behavior remains unchanged;
POST runs automatically, and the optional file system cleanup is not
performed.
