The first one is to create the username/password and assign it a privilege level (from 1 to 15, with 15 being the most privileged level). There are two steps involved to configure local usernames. Moreover, configuring local usernames on the device gives you the flexibility to add granularity regarding the levels of management privileges for different users ( although using an external AAA server for authentication and authorization purposes is better compared to local accounts).įor example, you can configure a username on the router with full privileges (privilege level 15) who can configure anything on the router, or you can configure a username with unprivileged access (privilege level 1) who can only see a few things on the router and nothing else. You only need to supply the “privileged EXEC” password (i.e the “ enable” password) in order to gain access to the full configuration mode of the router (read below about the different password levels and types).Įmploying an additional level of authentication (i.e requiring the user to supply an additional username/password credential in addition to the “enable” password) will make the router device more resistant to unauthorized access.
