NAME
ipstat - Reads IP network management statistics
SYNOPSIS
ipstat
DESCRIPTION
The ipstat command displays the read-only IP statistics concerning network
operation.
EXAMPLES
The following example invokes the ipstat command and the subsequent text
explains the statistical output from the command:
ipstat
Number of PDU's received
Number of correctly formatted IPDUs this system has received.
Number of PDU's transmitted
Number of IPDUs this system has transmitted.
Number of segmented PDU's received
Number of IPDUs this system has received as a series of segmented
data units.
Number of segmented PDU's transmitted
Number of IPDUs this system has segmented and successfully
transmitted.
Number of bytes of user data transmitted
Number of bytes of user data contained in Data Transfer (DT) IPDUs
this system has transmitted.
Number of bytes of user data received
Number of bytes of user data contained in Data Transfer (DT) IPDUs
this system has received.
Number of PDU fragments received
Number of incomplete (segmented) IPDUs this system has received.
Number of PDU fragments transmitted
Number of incomplete (segmented) IPDUs this system has transmitted.
Number of PDU fragments discarded
Number of incomplete (segmented) IPDUs this system has discarded.

Number of ER PDU's received
Number or Error Report (ER) IPDUs this system has received.
Number of ER PDU's transmitted
Number of Error Report (ER) IPDUs this system has transmitted.
Number of discarded PDU's unknown reasons (bad header)
Number of times this system has received an IPDU that contained
errors in the IP header, and therefore could not be parsed.
Number of discarded PDU's caused by bad checksum
Number of times this system has received an IPDU that contained a
checksum that indicated the IPDU was corrupt.
Number of discarded PDU's caused by unknown NSAP address
Number of times this system has discarded an IPDU because it
contained an unknown NSAP. In end systems, this counter increments
when the NSAP address IPDU contains does not match any NSAP address
specified for this system. In intermediate systems, this counter
increments when the system's dynamic or static routing table does
not contain a path to the end system whose NSAP address is
contained in the IPDU.
Number of discarded PDU's caused by lifetime expiration
Number of times this system has discarded an IPDU because it could
not be delivered to an end system within the specified lifetime of
the IPDU. IPDU lifetime expiration occurs only in intermediate
systems.
Number of discarded PDU's caused by invalid options
Number of times this system has discarded an IPDU because it
contained an invalid type 2 option, or any syntax error in the
options portion of the header.
Number of discarded PDU's caused by reassembly timeout
Number of times this system has discarded a segmented IPDU because
all segments of the IPDU were not received before the reassembly
timer expired.
Number of discarded PDU's caused by lack of
reassembly resources
Number of times this system has discarded a segmented IPDU because
the system did not have sufficient receive buffers or reassembly
data structures available.
Number of discarded PDU's caused by segmentation
not permitted
Number of times this system has discarded an IPDU because the IPDU
was segmented, but segmentation had been disabled.

Number of discarded PDU's caused by inactive subset used
Number of times this system has received an IPDU that was built
under the Inactive Network Layer Protocol (INLP) when the system's
ability to receive an INLP IPDU was disabled.
Number of inactive subset PDUs transmitted
Number of IPDUs transmitted due to inactive subset.
Number of inactive subset PDUs received.
Number of IPDUs recieved due to inactive subset.
DIAGNOSTICS
could not open device
Cause: the TP4/IP module could not be opened, probably because the
STREAMS stack is not initialized, or OSI/LAN has not been
installed.
Action: invoke the osid stack configuration utility, or install
the OSI/LAN software.
