8.11.5 TACACS+ Authentication Setup

Use this screen to configure your TACACS+ server settings. See
more information on TACACS+ servers. To open this screen, select a device which supports this
ENC User's Guide
DESCRIPTION
This field only applies if you configure multiple RADIUS servers.
Select index-priority and the device tries to authenticate with the first configured
RADIUS server, if the RADIUS server does not respond then the device tries to
authenticate with the second RADIUS server.
Select round-robin to alternate between the RADIUS servers that it sends
authentication requests to.
Specify the amount of time in seconds that the device waits for an authentication
request response from the RADIUS server.
If you are using index-priority for your authentication and you are using two
RADIUS servers then the timeout value is divided between the two RADIUS
servers. For example, if you set the timeout value to 30 seconds, then the device
waits for a response from the first RADIUS server for 15 seconds and then tries the
second RADIUS server.
The first column displays a read-only number representing a RADIUS server entry.
Enter the IP address of an external RADIUS server in dotted decimal notation.
The default port of a RADIUS server for authentication is 1812. You need not
change this value unless your network administrator instructs you to do so.
Specify a password (up to 32 alphanumeric characters) as the key to be shared
between the external RADIUS server and the device. This key is not sent over the
network. This key must be the same on the external RADIUS server and the
device.
Click Apply to save your changes.
Click Reset to discard your changes and reset the fields to their settings last time
