12.6.2.2 ASAP Card Ether Ports Utilization Window

The Ether Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the
Ethernet ports during consecutive time segments. The Utilization window provides an Interval menu that
enables you to set time intervals of 1 minute, 15 minutes, 1 hour, and 1 day. Line utilization is calculated
with the following formulas:
Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate
The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction
for the Ethernet port (that is,1 Gbps).

Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.

ASAP Ethernet Statistics Parameters (continued)
Meaning
A count of frames for which reception on a particular interface
fails due to an internal MAC sublayer receive error. A frame is
only counted by an instance of this object if it is not counted by
the corresponding instance of either the
dot3StatsFrameTooLongs object, the
dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors
object. The precise meaning of the count represented by an
instance of this object is implementation-specific. In particular,
an instance of this object may represent a count of receive
errors on a particular interface that are not otherwise counted.
A count of frames for which transmission on a particular
interface fails due to an internal MAC sublayer transmit error.
A frame is only counted by an instance of this object if it is not
counted by the corresponding instance of either the
dot3StatsLateCollisions object, the
dot3StatsExcessiveCollisions object, or the
dot3StatsCarrierSenseErrors object. The precise meaning of the
count represented by an instance of this object is
implementation-specific. In particular, an instance of this
object might represent a count of transmission errors on a
particular interface that are not otherwise counted.
