message. With the secure-cli command enabled on the system, the CONFIGURATION mode does not
display the root access password option.
When you configure the root access password, ensure that your password meets the following criteria:
● A minimum of eight characters in length
● A minimum of one lower case letter (a to z)
● A minimum of one upper case letter (A to Z)
● A minimum of one numeric character (0 to 9)
● A minimum of one special character including a space (" !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~")
If your password does not meet the criteria, the system does not accept your password.
If you use encryption type 9, the system stores the clear text password in an inaccessible location
on the system. The show running-configuration command does not display the password. This
configuration is not portable between different systems.
Example
DellEMC)# show running-config | g root
root-access password 7
