## Procedure

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

2. Click Statistics Summary, then click Authentication.

The following information appears:

> Index (casIndex)

> Protocol (casProtocol)

> IP Address (casAddress)

> Requests (casAuthenRequests)

> Request Timeouts (casAuthenRequestTimeouts)

> Unexpected Resp (casAuthenUnexpectedResponses)

> Server Error Resp (casAuthenServerErrorResponses)

> Incorrect Resp (casAuthenIncorrectResponses)

> Resp Time (casAuthenResponseTime)

> Trans Successes (casAuthenTransactionSuccesses)

> Trans Failures (casAuthenTransactionFailures)

### Index (casIndex)

AAA Server Table index.

### Protocol (casProtocol)

Protocol used with this server.

tacacsplus(1) represents TACACS+

radius(2) represents RADIUS

### IP Address (casAddress)

Server IP address.

### 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.

### Resp Time (casAuthenResponseTime)

Average response time for authentication requests sent to server since system reinitialization, excluding timeouts.

### Trans Successes (casAuthenTransactionSuccesses)

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 Failures (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.
