# AAA Server Statistics- Authorization

The AAA Server Statistics- Authorization, allows comparison of various statistical details among the servers.

## Procedure

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

2. Click Statistics Summary, then click Authorization.

The following information appears:

> Index (casIndex)

> Protocol (casProtocol)

> IP Address (casAddress)

> Requests (casAuthorRequests)

> Request Timeouts (casAuthorRequestTimeouts)

> Unexpected Resp (casAuthorUnexpectedResponses)

> Server Error Resp (casAuthorServerErrorResponses)

> Incorrect Resp (casAuthorIncorrectResponses)

> Resp Time (casAuthorResponseTime)

> Trans Successes (casAuthorTransactionSuccesses)

> Trans Failures (casAuthorTransactionFailures)

### 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 (casAuthorRequests)

Number of authorization requests sent to server since it was made active.

Retransmissions due to timeout requests are counted as distinct requests.

It is not instantiated for protocols that do not support a distinct authorization function.

### Request Timeouts (casAuthorRequestTimeouts)

Number of authorization requests timed out since server was made active.

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

It is not instantiated for protocols that do not support a distinct authorization function.

### Unexpected Resp (casAuthorUnexpectedResponses)

Number of unexpected authorization responses received from server since it was made active; for example, a delayed response to a timed out request.

It is not instantiated for protocols that do not support a distinct authorization function.

### Server Error Resp (casAuthorServerErrorResponses)

Number of server ERROR authorization responses received from server since it was made active.

These responses show that server identified an error in its authorization operation.

It is not instantiated for protocols that do not support a distinct authorization function.

### Incorrect Resp (casAuthorIncorrectResponses)

Number of unprocessed authorization responses since server was made active.

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

It is not instantiated for protocols that do not support a distinct authorization function.

### Resp Time (casAuthorResponseTime)

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

It is not instantiated for protocols that do not support a distinct authorization function.

### Trans Successes (casAuthorTransactionSuccesses)

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

A transaction includes multiple retransmission requests when timeouts occur.

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

It is not instantiated for protocols that do not support a distinct authorization function.

### Trans Failures (casAuthorTransactionFailures)

Number of failed authorization 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.

It is not instantiated for protocols that do not support a distinct authorization function.
