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
Table
Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note
15.6.4.3 CE-Series Card Ether Ports History Window
The Ethernet Ether Ports History window lists past Ethernet statistics for the previous time intervals.
Depending on the selected time interval, the History window displays the statistics for each port for the
number of previous time intervals as shown in

CE-Series Card POS Ports Parameters
Definition
A time stamp indicating the last time that statistics were reset.
Indicates whether the Ethernet link is receiving a valid Ethernet signal
(carrier) from the attached Ethernet device; up means present, and down
means not present.
Number of bytes received since the last counter reset.
Number of received packets.
1
The number of inbound packets that were chosen to be discarded even
though no errors had been detected to prevent their being deliverable to a
higher-layer protocol. One possible reason for discarding such a packet
could be to free buffer space.
1
The number of inbound packets (or transmission units) that contained errors
preventing them from being deliverable to a higher-layer protocol.
Number of bytes transmitted since the last counter reset.
Number of transmitted packets.
1
Packets greater than 1518 bytes transmitted out a port.
2
Number of received GFP frames.
