Administrator	The super-user Administrator has complete access to all menus,	admin
	information, and configuration commands on the switch, includ-

RADIUS Attributes for Alteon OS User Privileges

When the user logs in, the switch authenticates his/her level of access by sending the RADIUS access request, that is, the client authentication request, to the RADIUS authentication server.

If the remote user is successfully authenticated by the authentication server, the switch will verify the privileges of the remote user and authorize the appropriate access. The administrator has an option to allow backdoor access via Telnet. The default is disable for Telnet access. Backdoor access is always enabled on the console port.

NOTE – To obtain the RADIUS backdoor password for your GbESM, contact your IBM Service and Support line.

All user privileges, other than those assigned to the Administrator, have to be defined in the RADIUS dictionary. RADIUS attribute 6 which is built into all RADIUS servers defines the administrator. The file name of the dictionary is RADIUS vendor-dependent. The following RADIUS attributes are defined for Alteon OS user privileges levels:
