Hello,
Amid my studies I came across the following assignment:
The applet must be triggered whenever someone exits configuration mode in a terminal session.
This requirement applies to terminal sessions on cty and on vty lines.
The applet must use CLI commands to achieve the following:
First, the applet must append the current time and date and the current startup configuration to a file in flash.
In this virtual environment, you have to use the unix keyword to identify the router flash file system. The name of the file should be config-changes,
so use unix:config-changes to specify the destination file.
Then, the applet must save the running configuration to NVRAM. Use the command write memory to save the configuration; do not use the command copy running-config startup-config.
Finally, the applet must append the newly saved startup configuration to the unix:config-changes file.
And next to my suggested solution, I was wondering whether there other ways to set up an EEM to accomplish the same goal.
Thanks.
