A RADIUS server can be used to create a database of multiple user name/password pairs with associated privilege levels for eachuser or group that require management access to a switch using the console port, Telnet, or Internet.When you are setting up privilege levels on the RADIUS server, level 0 allows Normal Exec access to the switch, and level 15 allows Privileged Exec access.The RADIUS Settings page contains the following editable fields:l Authentication — Select the authentication, or authentication sequence, required:¡ Radius — A RADIUS server authenticates the user.¡ Local — The switch authenticates the user.¡ Radius, Local — A RADIUS server attempts to authenticate the user first, and then the switch attempts to authenticate the user.¡ Local, Radius — The switch attempts to authenticate the user first, and then a RADIUS server attempts to authenticate the user.NOTE: The default user names are admin and guest, and the corresponding passwords are admin and guest. If you log in as guest (Normal Exec level),you can only view page information and change the guest password. If you log in as admin (Privileged Exec level), you can apply changes on all pages.Command Usageenable password [levellevel] {0 | 7} passwordUse this command to control access to the Privileged Exec level from the NormalExec level.
