"Test crash"

I learned of this command yesterday. It's "hidden", meaning that it doesn't show as a valid command when doing "test ?"

If you do "test crash" and hit enter, you get to a subcommand line "?>" with a lot of options.

What's the purpose of this command, and why would you ever use it? What would it tell you, and how is it useful?

Thanks,

John

Re: "Test crash"

It is used to generate Crash Info, you can simulate a crash scenario with it,

so you can crash the router with different options and then save the logs, and if in future router crashes in real, by matching logs you can find out the cause of crash.

Sounds dangerous to me :-)

Re: "Test crash"

It is used internally by Cisco for testing crashinfo generation , High Availability failover scenarios, etc.

There have been cases in the past where it was used to recover information from a router that has not crashed ( the command history), but I would not recommend using it unless instructed by a qualified techninical support representive.
