1 – local_nsap
o deleted remote nsap
This event is generated each time a remote NSAP is deleted.
Arguments: The event message lists all attributes for the deleted
entity.
1.1 – remote_nsap
o checksum failure
Generated each time a checksum validation fails on a received
TPDU.
o invalid tpdu received
Generated when a TPDU received from the remote NSAP is in
violation of the OSI transport protocol. If the error occurred
during connection establishment, a DR (disconnect request) TPDU
will be sent in response to the protocol error. If the error
occurred on an established transport connection, an ER (error)
TPDU will be sent in response to the protocol error. The remote
protocol error counter will be incremented. Arguments:
reject If an ER TPDU was transmitted or received, this is
cause the value of the reject cause parameter. If a DR was
transmitted, this is the value of the reason parameter.
erroneous The portion of the invalid TPDU transmitted or received
trans- in the invalid TPDU parameter of the ER or DR TPDU.
port PDU (OpenVMS only)
DNA The unique error number used to unambiguously
error distinguish between different errors. This number is
completely independent of the reason and reject cause
values defined by the OSI Transport protocol, the set
of which is too sparse to provide useful information.
o er tpdu received
Generated whenever an ER (error) TPDU is received from the remote
NSAP. The local protocol error counter will be incremented.
Arguments:
reject The value of the reject cause parameter in the received
cause ER TPDU.
erroneous The portion of the invalid TPDU received in the invalid
trans- TPDU parameter of the ER TPDU.

(OpenVMS only)
o local transport disconnection
Generated each time a connection attempt initiated by the remote
NSAP is rejected by the local NSAP. This does not include rejects
generated by the local user of the transport service. Thus, this
event is generated on the transmission of a DR TPDU in which
the reason parameter has a value other than 128. The reject sent
counter will be incremented. Argument:
DNA error This is the value transmitted in the additional
information parameter of the DR TPDU.
o remote transport disconnection
This event is generated each time a connection attempt initiated
from the local NSAP is rejected by the remote NSAP. This does
not include rejects requested by the remote user of the transport
service. Thus, this event is generated on the receipt of a DR
TPDU in which the reason parameter has a value other than 128
(which is a normal disconnect). The reject received counter will
be incremented. Arguments:
reason Reason why the event was generated and it is the
value received in the reason parameter of the DR
TPDU.
additional The value received in the additional information
informa- parameter of the DR TPDU. If the remote NSAP is a
tion DNA OSI Transport implementation, the additional
information parameter will have one of the following
values:
'01'H Too much user data in CR (connection
request) or CC (connection confirm) TPDU
'02'H Proposed TPDU size invalid
'05'H Invalid protocol class requested
'07'H Illegal negotiation attempted
'08'H Invalid parameter in TPDU
'09'H TPDU header length invalid
'0A'H Parameter length error in TPDU header
'0B'H TPDU longer than negotiated maximum
'0C'H Segmentation of expedited data illegal
'0D'H Invalid parameter value
'10'H Invalid TPDU type
'12'H Expedited data out of sequence
'40'H Unknown transport selector
'41'H Proposed protocol class(es) unavailable
'42'H Insufficient resources
'43'H Maximum connections already active
'80'H Unknown reference
'81'H Connection timed out
'82'H Idle connection timed out
'83'H Unacknowledged ER TPDU
