Change passwords on multiple Catalyst and Nexus Switches

[Apish Hodler]

Hi all,

Its been sometime for me on the CLI and I started a new role that uses Catalyst 3k 9k and Nexus 9k etc, my last role for 6 years was full Meraki top to bottom

Ive been tasked with changing the password of 1 specific username on all of our switches. I don't think we have any services that can do this on all our devices simultaneously so i have to do it manually on each device.

I wanted to make sure i don't run into issues incase there something need to be aware of especially on the Nexus's in our data centers. We do have multiple admin accounts on the devices incase anything happens but i dont want to be the readon why we get locked out or anything going down.

Changing the password shouldn't disrupt anything correct? We have multiple stacks and various models.

from my memory its just

conf t

"The user name" cisco privilege 15 password 7 "new password"

On some of the devices  for eg theres only secret 5 or 9 and no privilege, how would i change those?

Hi,

conf t

Changing a password for one username should not disrupt anything, but still be careful not to lock yourself and others out of the systems.

On some of the devices  for eg theres only secret 5 or 9 and no privilege, how would i change those?

username test secret 9

username test password 7 <password>

If you are not sure, you can always set up a dummy username and password and test with that before you change the existing usernames.
