I get this message on a new 2901 Cisco router:
Cisco Configuration Professional (Cisco CP) is installed on this
device and it provides the default username "cisco" for one-time use.
If you have already used the username "cisco" to login to the router
and your IOS image supports the "one-time" user option, then this
username has already expired. You will not be able to login to the
router with this username after you exit this session.It is strongly suggested that you create a new username with a
privilege level of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>Replace and with the username and password you
want to use.
It appears every time I login and everytime I show run. I already set up my username. How do I turn it off?
