Monitoring PPP Interfaces (Talk 5)

Packets

The total number of PAP packets sent or received.

Octets

The number of bytes of data that were sent or received in those packets.

Requests

The number of PAP ªRequestº packets sent or received. These are the packets which contain the PAP name/password pairs.

Acks The number of Acks (success replies) sent or received for the PAP requests (for example, if the peer sends a valid Request packet, the router replies with an Ack).

Naks The number of Naks sent or received for the PAP requests (for example, if the peer sends an invalid Request packet, the router replies with a Nak).

Packets

 

The total number of CHAP packets sent or received.

 

Octets

 

The number of bytes of data that were sent or received in the

 

packets.

 

Challenges

 

The number of CHAP ªChallengeº packets sent or received. A

 

CHAP Challenge packet includes a randomly generated encryption

 

key and is a demand on the peer to generate a suitable response

 

based on that key and on stored password information.

 

Responses

 

The number of CHAP ªResponseº packets sent or received. A

 

Response packet contains a peer's answer to a ªChallengeº

 

request.

 

Successes/Failures

 

The number of Success or Failure packets sent or received. A unit

 

sends out a Challenge packet and waits for the peer's Response

 

reply. It then examines the Response packet and sends a Success

 

or Failure packet to indicate whether the Response was valid.

 

These counters re¯ect the number of Success or Failure packets

 

sent. A peer gets several tries to respond successfully before

 

authentication is considered to have failed.
