NS3000/iX FDDI Link Statistics
The following section describes the data that is output when you issue
the LINKCONTROL command to obtain statistics relating to NS3000/iX FDDI
Links.
LINKSTATE Parameter Fields
Figure A-11 provides an example of the data that is displayed when you
issue the LINKCONTROL linkname;STATUS=LINKSTATE command:
Linkname: FDDILINK Linktype: FDDI Linkstate: RING UP
Figure A-11. LINKSTATE Command for FDDI Link
CONFIGURATION Parameter Fields
The CONFIGURATION parameter for FDDI links displays several fields in
addition to the LINKSTATE parameter field. Figure A-12 provides an
example of the data that is displayed when you issue the LINKCONTROL
linkname;STATUS=CONFIGURATION command:
Physical Path: 0/28
Current Station Address: 08-00-09-09-63-67
Default Station Address: 08-00-09-09-63-67
Current Multicast Address List is empty
Figure A-12. FDDI CONFIGURATION Parameter Output
Physical Path. The Physical Path field displays the current physical
path for the FDDI card as specified in the NMMGR configuration file.
Current Station Address. The Current Station Address field is a display
of the six (6) byte address to which the node is configured to respond.
This address is used whenever frames are sent to the network media. The
default station address is used unless it is overridden in the NMMGR link
configuration screen. If this field is changed, then the station address
of this node is changed. Make sure that you note this new address in the
system manager log.
Default Station Address. The Default Station Address field is the
default value for the Current Station Address described above. The
default station address is determined by the specific FDDI card.
Current Multicast Address List. This is a list of all multicast
addresses that have been configured for this link. These multicast
addresses are those to which this node will now respond.
STATISTICS Parameter Fields
The STATISTICS parameter for FDDI links displays many fields in addition
to the LINKSTATE parameter fields. The CONFIGURATION parameter fields
are not displayed when this parameter is used. Figure A-13 provides an
example of the data that is displayed when you issue the LINKCONTROL
linkname;STATUS=STATISTICS command:
Transmits no error 41337 Receives no error 41859
SMT uni xmits 16347 SMT uni rec 16347
SMT non-uni xmits 16406 SMT non-uni rec 16347
SMT xmit bytes 2392533 SMT rec bytes 2386662
Transmit errors 0 SMT rec errors 0
Receive errors 4 Receives lost 26
Receives not copied 0 Receives discarded 212
Figure A-13. FDDI STATISTICS Parameter Fields
This command displays statistics about the data transmitted across the
link. All field values are summations.

transmitted by this station. This count excludes all MAC frames.
Receives no error. The number of frames addressed to and successfully
received by this station.
SMT uni xmits. The number of unicast frames transmitted by the SMT
module on this station (reference: FDDI Station Management Standards
document)

frames transmitted by the SMT module on this station (reference: FDDI
Station Management Standards document)
SMT uni rec. The number of non-unicast (multicast and broadcast) frames
received by the SMT module on this station (reference: FDDI Station
Management Standards document)
SMT xmit bytes. The number of bytes of data transmitted by the SMT
module on this station.
SMT rec bytes. The number of bytes of data received by the SMT module on
this station.
Transmit errors. The number of frames aborted or not transmitted by this
station.
SMT rec errors. The number of frames with errors received by the SMT
module on this station.
Receive errors. The number of all error frames that were detected by
this station and no previous station.
Receives lost. The number of frames received that had an error.
Receives not copied. The number of frames addressed to this station but
not copied into a receive buffer because there was no room for them.
Receives discarded. The number of frames received by this station that
were discarded due to errors, invalid addresses, or lack of resources.
ALL Parameter Fields
The ALL parameter for FDDI links displays a combination of all fields
presented by the LINKSTATE, CONFIGURATION, and STATISTICS commands.
Please reference the previous sections for descriptions of the various
fields.
DIAGNOSTIC Parameter Fields
The DIAGNOSTIC parameter for FDDI links displays all fields presented by
the ALL parameter plus several additional fields that might be useful for
HP representatives trying to debug FDDI link related problems. Brief
descriptions will be given here; however, please note that some
descriptions will be meaningful only to HP factory representatives.
Figure A-14 provides an example of the additional fields displayed by
this command.

Figure A-14. FDDI DIAGNOSTICS Parameter Fields
Writes completed. The number of data packets successfully sent from the
driver to the FDDI card. The maximum value is two billion (2^31).
Reads completed. The number of packets received from the FDDI card by
the driver. The maximum value is two billion (2^31).
Write bytes. The total number of bytes in all packets transmitted by the
driver. The maximum value is one quadrillion (10^15).
Read bytes. The total number of bytes in all packets received by the
driver. The maximum value is one quadrillion (10^15).
Unicast writes. The number of unicast packets transmitted by the driver.
Unicast reads. The number of unicast packets received by the driver.
Multicast writes. The number of multicast packets transmitted by the
driver.
Multicast reads. The number of multicast packets received by the driver.
Broadcast writes. The number of broadcast packets transmitted by the
driver.
Broadcast reads. The number of broadcast packets received by the driver.
Writes aborted. The number of times the transmit abort bit was set in
the IO_RX_STATUS register at the completion of a packet transmission.
Reads aborted. The number of times the status length field in the read
buffer trailer indicated that the received buffer is not valid.
Outbound high water. The maximum number of outbound packets queued
within the driver awaiting transmission.
Non-routable reads. The number of inbound packets that did not have a
valid destination SAP address.
Num of heartbeats. The number of heartbeat requests passed between the
driver and the card. Also the number of seconds since the driver was
configured ( one hearbeat per second ).
Subset buffer reqs. The number of times the driver has made a subset
allocation buffer manager request.
Number of users. The number of network transports that have configured
with the driver.
Num of subset bufs. The total number of buffers received from all the
subset allocation requests made during the life of the driver. Dividing
this number by the Subset buffer reqs value yields the average number of
buffers returned per request.
Num of power fails. The number of times that a system powerfail has been
detected during the life of the driver.
Queued buffer reqs. The number of times the driver has made a queued
buffer manager request.
Ring up time. The number of seconds the FDDI ring has been up since the
driver was started. Subtracting this number from the Num of heartbeats
value will provide the number of seconds that the ring has been down.
Note the ring being down does not by itself indicate a problem with this
node. The ring will not be up unless the FDDI concentrator and other
nodes are configured and active.
Read buffs in pool. The number of buffers in the inbound buffer pool.
Ring drops. The number of times the ring down signal has been received
during the life of the driver.
Read buffs avail. The number of buffers in the inbound buffer pool that
are currently queued within the driver.
Loquix reinits. The number of times the Loquix chip has been
reinitialized.
Read buffer size. The size in bytes of the buffers in the inbound buffer
pool.
SMT events. The number of SMT events received by the driver.
Flag Status
The status of several flags are printed here. If a flag's status is not
reported here then that flag is NOT set. The meaning each flag is
briefly described here.
Io_tx. The IO_TX_STATUS register has been read since the last card
interrupt.
Io_cmd. The IO_CMD_STATUS register has been read since the last card
interrupt.
Lan_in_active. An inbound DMA buffer has been posted to the card.
