protocol State

Protocol state information. See specific protocol state fields for information.

None specified

AUTHENTICATION

Challenge-Handshake Authentication Protocol (CHAP) authentication state information. See Authentication field for information.

None specified

LCP

LCP information:

State—LCP protocol state:

Ack-rcvd—A Configure-Request has been sent and a Configure-Ack has been received.

Ack-sent—A Configure-Request and a Configure-Ack have both been sent, but a Configure-Ack has not yet been received.

Closed—Link is not available for traffic.

Opened—Link is administratively available for traffic.

Req-sent—An attempt has been made to configure the connection.

Last started—LCP state start time.

Last completed—LCP state completion time.

Negotiated options:

ACFC—Address and-Control Field Compression. A configuration option that provides a method to negotiate the compression of the Data Link Layer Address and Control fields.

Asynchronous map—Asynchronous control character map. A configuration option used on asynchronous links such as telephone lines to identify control characters that must be replaced by a two-character sequence to prevent them from being interpreted by equipment used to establish the link.

Authentication protocol—Protocol used for authentication. This option provides a method to negotiate the use of a specific protocol for authentication. It requires a peer to authenticate itself before allowing network-layer protocol packets to be exchanged. By default, authentication is not required.

Authentication algorithm—Type of authentication algorithm. The Message Digest algorithm (MD5) is the only algorithm supported.

Endpoint discriminator class—For multilink PPP (MLPPP), a configuration option that identifies the system transmitting the packet. This option advises a system that the peer on this link could be the same as the peer on another existing link.

Magic number—A configuration option that provides a method to detect looped-back links and other data-link layer anomalies. By default, the magic number is not negotiated.

MRU—Maximum receive unit. A configuration option that may be sent to inform the peer that the implementation can receive larger packets, or to request that the peer send smaller packets. The default value is 1500 octets.

MRRU—For multilink PPP, the maximum receive reconstructed unit. A configuration option that specifies the maximum number of octets in the Information fields of reassembled packets.

Multilink header suspendable classes—For MLPPP, an LCP option that advises the peer that the implementation wishes to receive fragments with a format given by the code number, with the maximum number of suspendable classes given.

Multilink header format classes—For MLPPP, an LCP option that advises the peer that the implementation wishes to receive fragments with a format given by the code number.

PFC—Protocol-Field-Compression. A configuration option that provides a method to negotiate the compression of the PPP Protocol field.

short sequence—For MLPPP, an option that advises the peer that the implementation wishes to receive fragments with short, 12-bit sequence numbers.

Authentication

CHAP authentication state information:

Chap-ans-rcvd—Packet was sent from the peer, indicating that the peer received the Chap-resp-sent packet.

Chap-ans-sent—Packet was sent from the authenticator, indicating that the authenticator received the peer's Chap-resp-rcvd packet.

Chap-chal-rcvd—Challenge packet has been received by the peer.

Chap-chal-sent—Challenge packet has been sent by the authenticator to begin the CHAP protocol or has been transmitted at any time during the Network-Layer Protocol (NCP) phase to ensure that the connection has not been altered.

Chap-resp-rcvd—CHAP response packet has been received by the authenticator.

Chap-resp-sent—CHAP response packet has been sent to the authenticator.

Closed—Link is not available for authentication.

Failure—Authenticator compares the response value in the response packet from the peer with its own response value, but the value does not match. Authentication fails.

Success—Authenticator compares the response value in the response packet from the peer with its own response value, and the value matches. Authentication is successful.

None specified

IPCP

primary DNS server—Negotiate with the remote peer to select the address of the primary DNS server to be used on the local end of the link.

primary WINS server—Negotiate with the remote peer to select the address of the primary WINS server to be used on the local end of the link.

remote address—IP address of the remote end of the link in dotted quad notation.

secondary DNS server—Negotiate with the remote peer to select the address of the secondary DNS server to be used on the local end of the link.

secondary WINS server—Negotiate with the remote peer to select the address of the secondary WINS server to be used on the local end of the link.
