NAME
tp4stat - Reads ISO/OSI TP4 (transport layer) network management
statistics
SYNOPSIS
tp4stat
DESCRIPTION
The tp4stat command reads the various statistics TP4 keeps concerning
network operation.
EXAMPLE
The following example shows starting the tp4stat command, and the
subsequent text illustrates the command output:
tp4stat
Number of open and established connections

retransmitted TPDUs.
Total number of TPDU's received

transmitted. This number does not include retransmitted TPDUs.
Number of DT TPDU's received
Number of complete Data Transfer (DT) TPDUs this system has
received.
Number of AK TPDU's transmitted
Number of Acknowledge (AK) TPDUs this system has transmitted,
including duplicated AK TPDUs.
Number of AK TPDU's received
Number of Acknowledge (AK) TPDUs this system has received,
including duplicates.

This count does not include retransmitted ED TPDUs.
Number of ED TPDU's received
Number of Expedited Data (ED) TPDUs this system has received.
Number of UD TPDU's transmitted
Number of Unit Data (UD) TPDUs this system has transmitted.
Number of UD TPDU's received
Number of Unit Data (UD) TPDUs this system has received.
Total number of TPDU's retransmitted
Number of retransmitted Connect Request (CR), Connect Confirm
(CC), Data Transfer (DT), Expedited Data (ED) , and Disconnect
Request (DR) TPDUs this system has retransmitted.
Number of DT TPDU's retransmitted
Number of Data Transfer (DT) TPDUs this system has retransmitted.
Number of ED TPDU's retransmitted
Number of Expedited Data (ED) TPDUs this system has retransmitted.
Number of receive window closures
Number of credit reductions in which the window is closed after the
reduction.
Number of credit reductions
Number of credit reductions in which the window remains open after
the reduction.
Number of duplicate DT TPDU's received
Number of duplicate Data Transfer (DT) TPDUs this system has
received and discarded.
Number of duplicate ED TPDU's received
Number of duplicate Expedited Data (ED) TPDUs this system has
received and discarded.
Number of out of window DT TPDU's rcvd
Number times this system has received a Data Transfer (DT) TPDU
with a sequence number higher than the upper window edge.
Number of out of sequence AK TPDU's rcvd
Number of times this system has received an out-of-sequence
Acknowledge (AK) TPDU. This counter does not include duplicate AK
TPDUs.
Successfully established incoming connections
Number of times this system has received a Connect Request (CR)
TPDU that resulted in an established connection.

Successfully established outgoing connections
Number of times this system has transmitted a Connect Request (CR)
TPDU that resulted in an established connection.
Number of rejected incoming connections
Number of times this system has received a Connect Request (CR)
TPDU that did not result in an established connection.
Number of rejected outgoing connections
Number of times this system has transmitted a Connect Request (CR)
TPDU that did not result in an established connection.
Number of user rejected incoming connections
Number of times a TSU of this system has rejected an incoming
connection.
Incoming CR TPDU's rejected due to configuration
Number of times this system has received a Connect Request (CR)
TPDU, and responded to it with a Disconnect Request (DR) TPDU.
This counter is incremented when the Transport reason code returned
is 2, 3, 130, 131, 132, 135 or 136.
Outgoing CR TPDU's rejected due to configuration
Number of times the system has received a Disconnect Request (DR)
TPDU in response to a Connection Request (CR) TPDU it transmitted.
This counter is incremented when the Transport reason code returned
is 2, 3, 130, 131, 132, 135 or 136.
Incoming CR TPDU's rejected due to protocol error
Number of times the system has received a TPDU and rejected it
because it contained a protocol error. This counter is incremented
when the Transport reason code returned is 0, 133, or 138.
Outgoing CR TPDU's rejected due to protocol error
Number of times the system received a Disconnect Request (DR) or
Error Report (ER) TPDU in response to a Connect Request (CR) TPDU.
This counter is incremented when the Transport reason code returned
is 0, 133, or 138.
Number of TPDU transmission timeout's
Number of instances in which the system has retransmitted a TPDU
the maximum number of times without receiving any response.
Number of inactivity timeout's
Number of times a Transport state machine in the system has timed
out because no TPDUs were received on the connection.
Number of received TPDU's causing a protocol error
Number of TPDUs the system receives which contain a protocol error
and cause the Transport protocol to transmit a Disconnect Request
(DR) TPDU. This TPDU will contain the Transport reason code 133.

tp4stat(8) CLIX tp4stat(8)
Number of DR or ER TPDU received indicating a
protocol error
Number of times the system has received a Disconnect Request (DR)
or Error Report (ER) TPDU indicating that a TPDU that the system
transmitted previously (other than a CR TPDU) contained a protocol
error.
Number of TPDU's with invalid checksum
Number of times the system discarded a TPDU because the checksum
indicated that the TPDU was bad.
Number of received TPDU's ignored (bad header)
Number of times the system received a TPDU having an incorrect
header.
Number of received and ignored UD TPDU's
Number of times the system received a Unit Data (UD) TPDU and
discarded it for any reason.
DIAGNOSTICS
could not open device
Cause: the TP4/IP driver has not been installed.
Action: reinstall OSI/LAN software in the kernel.
