Parts of Statistics Tables
The tables of statistics contain the following columns:
■
Statistics — Type of statistic being tracked.
■
# of Wraps — Number of times the Counter value wraps, for statistics that
grow rapidly. The maximum value that either the Counter or the # of Wraps
can hold is 2
32
, or 4,294,967,296. Each time the Counter field reaches the
maximum value of 2
32
, the wrap count is incremented by 1.
■
Counter — Number of instances of the tracked item recorded since system
initialization or the last time the counters were cleared.
Traffic Transmit and Receive Statistics
The Traffic Statistics include these transmit and receive values.
■
Frames Rx — Number of frames that the port has received.
■
Frames Tx — Number of frames that the port has transmitted.
■
Four byte words Rx — Number of words that the port has received.
■
Four byte words Tx — Number of words that the port has transmitted.
■
Offline sequences Rx — Number of offline sequences (OLS) received by
this port.
■
Offline sequences Tx — Number of offline sequences (OLS) transmitted by
this port.
■
Link resets Rx — Number of link reset protocol frames received by this port
from the attached N_Port.
■
Link resets Tx — Number of link reset protocol frames transmitted by this
port to the attached N_Port.
■
Link utilization % Rx — Current link utilization for the port expressed as a
percentage. On 1 Gb/s links, ports can transmit or receive data at 100 MB per
second. On 2 Gb/s links, ports can transmit or receive data at 200 MB per
second. Link utilization is calculated over one-second intervals.
■
Link utilization % Tx — Current link utilization for the port expressed as a
percentage. On 1 Gpbs links, ports can transmit or receive data at 100 MB per
second. On 2 Gb/s links, ports can transmit or receive data at 200 MB per
second. Link utilization is calculated over one-second intervals.
