We have fired the company who supported our 2811 routers and I would like to know how to change the Administrator password so we can prevent their access while we are looking for a replacement company

You can reduce your risk by creating another account before deleting the admin account.
username administrator secret MyPaSsWoRd
Then create another telnet session (leave the original one open) and authenticate with the username administrator. If successful you can delete admin and re-create or just use the administrator account.

David,
Make sure the new one is working fine before you delete the old one.
the command to delete the old one is:
config t
no username admin

How are you gaining access? SSH? Telnet? is tacacs or radius being used?
10-06-2009 01:03 PM
Telnet using CLI commands and I login as user admin
10-06-2009 12:49 PM
Assuming you're using local authentication;
no username administrator
To create a new one-
username administrator secrete mYPaSsWoRd

I currently access the 2811 using a telnet connection and CLI commands and login as Admin which has all rights and then the system uses the same password for login and enable functions.
10-06-2009 01:06 PM
no username admin
To create a new one-
username admin secrete mYPaSsWoRd

Thanks but I am not sure I understand, there is a current username admin that I use to login to the router. You are suggesting creating a new one. Is that to overwrite/replace the current user? Maybe I should wait until I find a new company and run the risk.

First you delete the username admin. Next your creating a new admin account so you can login with that account and the new password.
