L2TP Disconnect Cause Codes
Code Name Description
1 admin The disconnection was a result of direct administrative action,
disconnect including:
2 renegotiation Code 2 is not used; the E Series LNS is always capable of
disabled renegotiating LCP if proxy data is not available.
3 normal Indicates that one of the following events occurred:
disconnect
The E Series LNS determines by inference that a normal disconnect
has occurred for direction 1. The LNS does this when the peer
initiates LCP termination after proceeding beyond the successful
negotiation of LCP (that is, after starting authentication signaling or
NCP negotiation).
4 compulsory Code 4 with direction 2 is generated if the following conditions are
encryption met:
refused
Code 4 with direction 1 is never generated, because the E Series
LNS never requests ECP.
5 lcp failed to An LCP configuration error prevented LCP from converging; the two
converge peers attempted to negotiate but did not agree on acceptable LCP
parameters.
6 lcp peer silent LCP negotiation timed out; the LNS did not receive any LCP packets
from the LAC.
7 lcp magic A magic number error was detected; this indicates a possible looped
number error back link.
8 lcp keepalive The keepalive drop count was exceeded.
error
9 lcp mlppp Code 9 is not used. Dynamic MLPPP bundling, which is the only
endpoint kind of MLPPP bundling supported for MLPPP/L2TP, uses the
discriminator endpoint discriminator as part of the key for bundle selection.
mismatch Therefore, there will never be an unexpected endpoint discriminator
for an existing MLPPP bundle.
The administrator shut down the network or link interface.
The administrator logged out the subscriber.
user-initiated logout (direction 1)
session timeout (direction 2)
inactivity timeout (direction 2)
address lease expired (direction 2)
The peer initiates LCP termination without having proceeded
beyond the completion of LCP negotiation, and
Prior to receiving the terminate request from the peer, the local
LCP has sent a Protocol Reject in response to any packet for
Encryption Control Protocol (ECP) protocols (protocol codes
0x8053, 0x8055) from the peer.
