12.6.2.5 ASAP 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 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 * 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 maxBaseRate for ASAP cards is shown in
page
Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note
12.6.2.6 ASAP Card POS Ports History Window
The Ethernet POS Ports History window lists past Ethernet POS Ports statistics for the previous time
intervals. The History window displays the statistics for each port for the number of previous time
intervals as shown in
