of information. If you do not enter the page keyword, the output scrolls. It does not stop for page breaks.
If you enter the password keyword, password encryption is enabled, but only the encrypted form appears
in the output.
If you do not enter the password keyword, passwords and other security-sensitive information in the
output are replaced in the output with the word “removed.”
The show tech-support commands are a compilation of several show commands and the output can be
quite lengthy. For a sample display of the output of the show tech-support command, see the individual
