L2TP Disconnect Cause Codes
Code Name Description
17 ncp no Code 17 is generated only if an NCP configuration error has
negotiation prevented NCP negotiation from converging. This occurs when the
completed two peers do not agree on acceptable NCP parameters within the
time allowed for upper-layer negotiation.
Code 19 takes precedence over code 17 in situations related to
address convergence failure.
18 ncp no ncps No NCPs were successfully enabled within the time allowed for
available upper-layer negotiation.
19 ncp addresses An NCP configuration error has prevented NCP negotiation from
failed to converging on acceptable addresses. This occurs if the two peers
converge never agree on acceptable NCP addresses within the time allowed
for upper-layer negotiation.
The IPv6 interface identifier is considered an address for the purposes
of code 19.
Code 19 takes precedence over code 17 in situations related to
address convergence failure.
20 ncp negotiation
inhibited
Code 19 with direction 1 is generated if the peer denies address
parameters requested by the local NCP.
Code 19 with direction 2 is generated if the local NCP denies
address parameters requested by the peer.
Code 20 with direction 2 indicates that an upper layer
negotiation was inhibited for any enabled NCP because the
required network-layer parameters were not available as a result
of the authentication stage.
Code 20 with direction 1 is never generated; the NCPs are never
enabled if there is no non-null local address.
