# AAA Authentication

AAA Authentication monitors the authentication statistics of the server. The statistics is the delta value(present value - previous value) for a polling interval and the unit of measurement is "Nos/Interval".

## Procedure

1. Right-click the device, then select AAA.

2. Select a row of the Server Configuration Table, then click Authentication.

The following information appears:

> Requests (casAuthenRequests)

> Request Timeouts (casAuthenRequestTimeouts)

> Unexpected Resp (casAuthenUnexpectedResponses)

> Server Error Resp (casAuthenServerErrorResponses)

> Incorrect Resp (casAuthenIncorrectResponses)

> Trans Successes (casAuthenTransactionSucesses)

> Trans Failure (casAuthenTransactionFailures)

### Requests (casAuthenRequests)

Number of authentication requests sent to server when it is active.

Retransmissions due to timeout requests are counted as distinct requests.

### Request Timeouts (casAuthenRequestTimeouts)

Number of authentication requests timed out since the server was made active.

Timeout results in a retransmission request. Retransmissions stop when number of requests reaches maximum.

### Unexpected Resp (casAuthenUnexpectedResponses)

Number of unexpected authentication responses received since the server was made active. For example, a delayed response to a timed out request.

### Server Error Resp (casAuthenServerErrorResponses)

Number of server ERROR authentication responses received since the server was made active.

These responses mean that the server identified an error with its authentication operation.

### Incorrect Resp (casAuthenIncorrectResponses)

Number of unprocessed authentication responses since the server was made active.

Reasons are inability to decrypt response, invalid fields, or an invalid response to the request.

### Trans Successes (casAuthenTransactionSucesses)

Number of successful authentication transactions with this server since it was made active.

A transaction includes multiple retransmission requests when timeouts occur.

A transaction is successful when the server responds with either an authentication pass or fail.

### Trans Failure (casAuthenTransactionFailures)

Number of failed authentication transactions with this server since it was made active.

A transaction includes multiple retransmission requests when timeouts occur.

A transaction failure occurs when resends reach maximum or the server aborts the transaction.
