Timeout Select round-robin to alternate between the RADIUS servers that it sends authentication requests to. Specify the amount of time in seconds that the OLT waits for an authentication request response from the RADIUS server. Server 1 ~ 2 Port Secret TACACS+ Server Mode 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 OLT waits for a response from the first RADIUS server for 15 seconds and then tries the second RADIUS server. 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 OLT. This key is not sent over the network. This key must be the same on the external RADIUS server and the OLT. Use this section to configure your TACACS+ authentication settings.
