15.6.4.2 CE-Series 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
drop-down list 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). The maxBaseRate for CE-Series Ethernet cards is shown in

CE-Series Ether Port PM Parameters (continued)
Definition
The total number of octets of data (including those in bad packets) received
on the network (excluding framing bits but including FCS octets
2
Number of transmit packets that are collisions; the port and the attached
device transmitting at the same time caused collisions.
The total number of packets received that had a length (excluding framing
2
bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but
had either a bad FCS with an integral number of octets (FCS Error) or a bad
FCS with a nonintegral number of octets (Alignment Error).
2
Number of received frames dropped at the port level.
1
Number of received pause frames.
1
Number of transmitted pause frames.
Number of received packets dropped due to overflow in frame buffer.
1
Number of transmit queue drops due to drops in frame buffer.
1
1
Number of received control frames.
Number of received frames with length of 36 bytes or less.
1
Number of received frames that are too long. The maximum is the
1
programmed maximum frame size (for VSAN support); if the maximum
frame size is set to default, then the maximum is the 2112 byte payload plus
the 36 byte header, which is a total of 2148 bytes.
Number of received frames with CRC error.
1
Number of transmitted frames with CRC error.
1
Number of received packets that are too small.
