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

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

12.6.2 ASAP Card Ethernet Performance Monitoring Parameters
Meaning
Number of received frames with CRC error.
Number of received packets dropped due to overflow in frame
buffer.
Number of received packets that are too small.
Number of received frames with length of 36 bytes or less.
Number of received frames that are too long. The maximum is the
programmed max frame size (for VSAN support); if the max frame
size is set to default, then the max is 2112 byte payload plus 36 byte
header, which is 2148.
