NS 3000/iX FDDI Link Statistics
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 heartbeat 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.
