RTC
RTC
Description: A message was received that did not have a valid route. Telcon
generates this CENLOG.
Description: Route control got a message in, but no DCP-to-DCP sessions have been
configured. The message is discarded. Telcon generates this CENLOG.
SEQ NUMBER INVALID
Description: DUC received a network data unit (NDU) with an invalid sequence
number. The most common cause is UDLC sending a duplicate message. Telcon
generates this CENLOG.
Action: The long format displays the session table. The operator should ensure that
the session is recovered properly.
SNA: 676 - Received data ignored (discarded)
Description: This message occurs as a result of error or events in the Crossover
Application Bridge (XAB), which handles traffic between SNA resources and OS 2200
hosts. The probable cause is a software problem.
SNA: 1623 - Message could not be sent
Description: This message appears as a result of errors in the DTPLINK, the part of
SNA/net that enables SNA/net to communicate with other SNA/nets as if they were
physically adjacent. The probable cause is a software problem.
Unacked Frame
Description: The Common Network Management Service (CNMS) X.25 interface
module in PDNSVS received a discarded message notification. The reason is the port
processor never received an acknowledgment by the network for a frame that it had
sent. This event includes the LINE name.
R8: CNMS unrecoverable line error reason code
R10: PDNGRP STE index
Attributes affected: Supplementary text message, Line event. The X.25 PSCS
