X.25 Link Failure Error Codes
Listed below are the codes that are generated for X.25 link failures by
the Qualified Logical Link Control (QLLC) module. They are listed in
numerical order according to the ErrorNum displayed as part of these SNA
Transport logging messages:
Link connect failure on node NodeName
subsystem = SubsysID, procedure = ProcNum, error num = ErrorNum
Link failure, recovery in progress on node NodeName
subsystem = SubsysID, procedure = ProcNum, error num = ErrorNum
Link failure, shutting down the node NodeName
subsystem = SubsysID, procedure = ProcNum, error num = ErrorNum
The logging messages are described in "SNA Transport Logging Messages"
earlier in this appendix. The X.25 link-related ProcNum values are
described in "X.25 Link QLLC Internal Error Codes" later in this
appendix.
-14 MESSAGE BAD FRAME RECEIVED
CAUSE SNA/X.25 received an invalid QLLC control frame
(QLLU) from the remote system.
ACTION Try to reproduce the problem with link-level
tracing turned on. Also, call your
Hewlett-Packard support contact.
--------------------------------------------------------------------------
-15 MESSAGE REMOTE PROTOCOL ERROR
CAUSE The remote system sent a QLLC control frame
(QLLU) that violated the QLLC protocol. This
can be caused by software errors on the IBM
system or the HP 3000 system, or by the two end
nodes being out of sync.
ACTION Try to restart the SNA node. If the problem
continues, reproduce it with link-level tracing
turned on and call your Hewlett-Packard support
contact.
--------------------------------------------------------------------------
-38 MESSAGE QLLC INTERNAL ERROR
CAUSE The Qualified Logical Link Control (QLLC) module
has either encountered an internal error or
received an error notification from NETIPC.
ACTION Note the ProcNum displayed in the accompanying
logging message. Then, look at the message with
the corresponding number in "X.25 Link QLLC
Internal Error Codes" later in this appendix.
Also, call your Hewlett-Packard support contact.
--------------------------------------------------------------------------
-74 MESSAGE DATACOM LINE LOST
CAUSE The virtual circuit has terminated. That is, it
has been cleared, reset, or restarted.
ACTION Since this is a recoverable link error, restart
the SNA node. If the error still occurs, call
your Hewlett-Packard support contact.
--------------------------------------------------------------------------
-76 MESSAGE DISCONNECT TIMER POPPED
CAUSE The X.25 link has timed out while waiting for a
solicited Q disconnect (QDC) from the remote
system. The disconnect timer normally is
running when the link is in the process of
shutting down. Since the link is terminated
when the timer pops, the desired result
(shutting down the link) is achieved.
ACTION Note that the solicited QDC was never received.
No other action is necessary.
--------------------------------------------------------------------------
-77 MESSAGE INACTIVITY TIMER POPPED
CAUSE The time interval specified for Inactivity
Timeout has elapsed since any packets were sent
or received.
ACTION Use NMMGR or the configuration file critical
summary to ensure that the interval specified
for Inactivity Timeout is correct. If the
timeout occurs before a transaction is
completed, try increasing the value of
Inactivity Timeout. If the error still occurs,
call your Hewlett-Packard support contact.
--------------------------------------------------------------------------
-78 MESSAGE CONNECT TIMER POPPED
CAUSE The X.25 link has timed out waiting for a QSM
from the remote system.
ACTION Restart the SNA node. If the problem still
occurs, call your Hewlett-Packard support
contact.
--------------------------------------------------------------------------
-79 MESSAGE ALREADY CONNECTED
CAUSE SNA Transport has requested an SNA connection
for an X.25 link that is already connected.
ACTION Call your Hewlett-Packard support contact.
--------------------------------------------------------------------------
-80 MESSAGE DISCONNECT IN PROGRESS
CAUSE SNA Transport has requested an SNA connection or
disconnection while a QDC is pending from the
remote system.
ACTION Call your Hewlett-Packard support contact.
--------------------------------------------------------------------------
-81 MESSAGE CONNECT IN PROGRESS
CAUSE SNA Transport has requested an SNA connection or
disconnection while the QSM from the remote
system is pending.
ACTION Call your Hewlett-Packard support contact.
--------------------------------------------------------------------------
-83 MESSAGE UNEXPECTED QDC
CAUSE The remote system has sent an unsolicited Q
disconnect (QDC).
ACTION Restart the SNA node. If the problem still
occurs, call your Hewlett-Packard support
contact.
--------------------------------------------------------------------------
-84 MESSAGE UNEXPECTED QSM
CAUSE The remote system has sent a QSM after the SNA
connection has already been established.
ACTION Since this is a recoverable link error, the SNA
node will be revived. So, no action is
necessary.
