 To configure RADIUS parameters for login authentication:
1. Open the Authentication Settings page (Configuration tab > System menu >
Management > Authentication Settings).
Figure 16-4: Authentication Settings Page - RADIUS Configuration
2. From the 'Use RADIUS for Web/Telnet Login' drop-down list, select Enable to enable
RADIUS authentication for Web and Telnet login.
3. When implementing Web user access levels, do one of the following:
• If the RADIUS server response includes the access level attribute: In the
'RADIUS VSA Access Level Attribute' field, enter the code that indicates the
access level attribute in the VSA section of the received RADIUS packet. For
defining the RADIUS server with access levels, see ''Setting Up a Third-Party
RADIUS Server'' on page 242.
• If the RADIUS server response does not include the access level attribute:
In the 'Default Access Level' field, enter the default access level that is applied to
all users authenticated by the RADIUS server.
4. Configure RADIUS timeout handling:
a. From the 'Behavior upon Authentication Server Timeout' drop-down list, select
the option if the RADIUS server does not respond within five seconds:
♦ Deny Access: device denies user login access.
♦ Verify Access Locally: device checks the username and password
configured locally for the user (in the Web User Accounts page or Web
Users table), and if correct, allows access.
b. In the 'Password Local Cache Timeout' field, enter a time limit (in seconds) after
which the username and password verified by the RADIUS server becomes
invalid and a username and password needs to be re-validated with the RADIUS
server.
c. From the 'Password Local Cache Mode' drop-down list, select the option for the
local RADIUS password cache timer:
♦ Reset Timer Upon Access: upon each access to a Web page, the timer
resets (reverts to the initial value configured in the previous step).
♦ Absolute Expiry Timer: when you access a Web page, the timer doesn’t
reset, but continues its count down.
5. Configure when the Web Users table must be used to authenticate login users. From
the 'Use Local Users Database' drop-down list, select one of the following:
