Setting Up RADIUS AAA Service
3
If you log in to an admin account, you can change admin and user passwords. You must provide the old
password when the account being changed has the same or higher privileges than the current login
account. For example, when logged in as admin, you need admin passwords to change passwords for
admin accounts (except when you change the default user account password at login), but you do not
need user passwords to change passwords for user accounts.
A new password must have at least one character different from the old password. The following rules
also apply to passwords:
• You cannot change passwords using SNMP.
• Password prompting is disabled when security mode is enabled.
• Starting with Fabric OS v4.4.0, admin-level accounts can use Web Tools to change passwords.
• Starting with Fabric OS v3.2.0, you cannot change default account names.
For information on password behavior when you upgrade (or downgrade) firmware, refer to “Effects of
Firmware Changes on Accounts and Passwords” on page 4-7.
To change the password for the current login account
1. Connect to the switch and log in as either admin or user.
2. Enter the following command:
Enter the requested information at the prompts.
To change the password for a different account
1. Connect to the switch and log in as admin.
2. Enter the following command:
where name is the name of the account.
Enter the requested information at the prompts.
If the named account has lesser privileges than the current login account, the old password of the named
account is not required. If the named account has equal or higher privileges than the current login
account, you are prompted to enter the old password of the named account.
Setting Up RADIUS AAA Service
Fabric OS v3.2, v4.4.0, and later support RADIUS authentication, authorization, and accounting service
(AAA). When configured for RADIUS, a switch becomes a RADIUS client. In this configuration,
authentication records are stored in the RADIUS host server database. Login and logout account name,
assigned role, and time-accounting records are also stored on the RADIUS server for each user.
By default, RADIUS service is disabled, so AAA services default to the switch local database.
