Configuring RADIUS security
You can use a Remote Authentication Dial In User Service (RADIUS) server to secure the following
types of access to the Brocade Layer 2 Switch or Layer 3 Switch:
• Telnet access
• SSH access
• Web management access
• Access to the Privileged EXEC level and CONFIG levels of the CLI
NOTE
ServerIrons do not support RADIUS security for SNMP (IronView) access.
RADIUS authentication, authorization, and accounting
When RADIUS authentication is implemented, the ServerIron consults a RADIUS server to verify
user names and passwords. You can optionally configure RADIUS authorization, in which the
ServerIron consults a list of commands supplied by the RADIUS server to determine whether a user
can execute a command he or she has entered, as well as accounting, which causes the ServerIron
to log information on a RADIUS accounting server when specified events occur on the device.
NOTE
By default, a user logging into the device through Telnet or SSH first enters the User EXEC level. The
user can then enter the enable command to get to the Privileged EXEC level.
A user that is successfully authenticated can be automatically placed at the Privileged EXEC level
after login. Refer to “Entering privileged EXEC mode after a Telnet or SSH login” on page 131.
RADIUS authentication
When RADIUS authentication takes place, the following events occur.
1. A user attempts to gain access to the ServerIron by doing one of the following:
• Logging into the device using Telnet, SSH, or the Web Management Interface
• Entering the Privileged EXEC level or CONFIG level of the CLI
2. The user is prompted for a username and password.
3. The user enters a username and password.
4. The ServerIron sends a RADIUS Access-Request packet containing the username and
password to the RADIUS server.
5. The RADIUS server validates the ServerIron using a shared secret (the RADIUS key).
6. The RADIUS server looks up the username in its database.
