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 or PAP authentication state information.
For CHAP authentication:
-
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.
For PAP authentication:
-
Pap-resp-sent—PAP response sent to peer (ACK/NACK)t.
-
Pap-req-rcvd—PAP request packet received from peer.
-
Pap-resp-rcvd—PAP response received from the peer
(ACK/NACK).
-
Pap-req-sent—PAP request packet sent to the peer.
-
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.

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