a password.

applies only to the local node where the procedure is performed.

If you need to create another user name and password, complete the following steps:
a.
Click the Provisioning > Security tabs and click create .
b.
Fill in the fields with a new user name and password and assign a security level.
c. Click OK .
Note
After new user names and passwords are set up, including at least one Superuser, log in as a newly
created Superuser and delete the default CISCO15 username and otbu+1 password to ensure that security
is not compromised.
