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.

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

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.
