What information is NOT listed in "show run" ?

[MicJameson1]

On typical Cisco devices, as well as ASA's, what information is NOT listed in "show run" ?

Thank you.

Hello,

you could use an online tool like:

https://text-compare.com/

Copy and paste the output of 'sh run' and sh run all' to the two input fields, and click on 'Compare'. The differences will be highlighted. When you run the 'show' commands on your router, don't forget to set the command:

Router#terminal length 0

in order to avoid the 'more' prompt...

On a side note, there are a lot of 'hidden' exec commands that might be available, depending on your IOS version, and that do not show up at all in the running config. Below is a link to a rather comprehensive list.

" . . . what information is NOT listed in "show run" ?"

Many default statements.  Which ones are not shown varies by IOS.  (I have seen what's "hidden" vary immediately after an IOS upgrade.  This suppression is probably done to reduce the "clutter" when doing a show run without the optional "all" parameter.)
