15.6.4.5 CE-Series Card POS Ports Utilization Window

The POS Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the POS
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 * 8) / (interval * maxBaseRate)
Tx = (outOctets * 8) / (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 maxBaseRa te for CE-Series cards is shown in Table 15-14 on
page 15-31.
Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.

15.6.4.6 CE-Series Card POS Ports History Window

The Ethernet POS Ports History window lists past Ethernet POS ports 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 Table 15-15 on page 15-31. The listed
parameters are defined in Table 15-22 on page 15-47.
15.7 Performance Monitoring for Optical Cards
This section lists PM parameters for ONS 15454 optical cards, including the OC-3, OC-12, OC-48, and
OC-192 cards. Figure 15-20 shows the signal types that support near-end and far-end PMs.
