servers provide a centralized authentication method for web access.

To configure RADIUS security settings:

Figure 22: RADIUS Page

The RADIUS Page contains the following fields:

• Default Retries — Defines the default number of transmitted requests sent to the RADIUS server before a

failure occurs. Possible field values are 1-10.

• Default Timeout for Reply — Defines the default time interval in seconds that passes before the connection

between the device and the TACACS+ server times out. The field range is 1-60 seconds and the default is 10

seconds.

• Default Dead Time — Defines the default amount of time (in minutes) that a RADIUS server is bypassed for

service requests. The range is 0-2000.

• Default Key String — Defines the default key string used for authenticating and encrypting all RADIUS-

communications between the device and the RADIUS server. This key must match the RADIUS encryption.

• Source IP Address — Defines the default IP address of a device accessing the RADIUS server.

The RADIUS table lists known RADIUS servers and contains the following fields:

• # — Displays the RADIUS server number.

• IP Address — Displays the RADIUS server IP address.

• Priority — Displays the RADIUS server priority. The possible values are 1-65535, where 1 is the highest

value. The RADIUS server priority is used to configure the server query order.
