Table 79: PPP Disconnect Cause Codes (continued)
Description Name Code
The link attempted to join an existing MLPPP bundle whose peer
maximum received reconstructed unit (MRRU) did not match the
peer MRRU negotiated by the link. lcp mlppp mrru
not valid 10
Code 11 is not used; the short sequence number (SSN) option is not
supported. lcp mlppp peer
ssn invalid 11
Code 12 with direction 2 is generated when the following conditions
are met:
■
The peer initiates LCP termination without having proceeded
to NCP negotiation, and
■
Prior to the termination, the local LCP has responded with a
negative acknowledgement (NAK) to a callback option (LCP
option 13) from the peer.
The E Series LNS never generates code 12 with direction 1 because
the LNS never requests callback.
lcp callback
refused 12
Authentication failed because the authentication protocol timed out;
either the CHAP Authenticate Response or the PAP Authenticate
Request was not received. authenticate
timed out 13
Code 14 is not used. Dynamic MLPPP bundling, which is the only
kind of MLPPP bundling supported for MLPPP/L2TP, uses the
authenticated name as part of the key for bundle selection. Therefore,
there will never be an unexpected authenticated name for an existing
MLPPP bundle. authenticate
mlppp name
mismatch 14
No acceptable authentication protocol was negotiated by LCP.
■
Code 15 with direction 1 is generated if the peer rejected all of
the authentication protocols requested by the local LCP.
■
Code 15 with direction 2 is generated if the following conditions
are met:
■
The peer initiates LCP termination without having
proceeded beyond completion of NCP negotiation, and
■
During LCP negotiation, the local LCP responded with a
NAK to the final authentication protocol requested by the
peer.
authenticate
protocol refused 15
■
Code 16 with direction 1 is generated if the local authentication
of the peer fails (that is, the authenticator sent a PAP NAK or
CHAP Failure packet)
■
Code 16 with direction 2 is generated if the peer authentication
of the local LCP fails (that is, the authenticator received a PAP
NAK or CHAP Failure packet).
Note that there are a variety of causes for authentication failures,
including bad credentials (bad name, password or secret) and
resource problems.
