Solved: EEM script to check running-config changes with startup-config after reload

Saurabh Bassi · ‎06-28-2016

I am trying to track a bug which causes certain CLIs to disappear from the running-config after we reload the router.

Those CLIs were saved in startup-config before reloading the router.

Is there a EEM to compare running-config with startup-config line-by-line after reloading the router and syslog the lines which are missing from the running-config ?

You could do something simple like:

event manager applet compare-config

event timer cron cron-entry "@reboot"

action 1.0 cli command "enable"

action 2.0 cli command "show archive config diff nvram:startup-config system:running-config"

action 3.0 mail to "user@company.com" from "user@company.com" server "10.1.1.1" subject "Config diffs" body "$_cli_result"

Thank you Joe.

What does this command do ?

event timer cron cron-entry "@reboot"

and how does it accomplish the task after reboot ?

This schedules the EEM policy to run after each reboot.
