15.7 Performance Monitoring for Optical Cards
15.6.4.5 CE-Series Card POS Ports Utilization Parameters
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 CE-Series cards is shown in Table 15-8 on
page 15-20.
Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
15.6.4.6 CE-Series Card Ether Ports History Parameters
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 15-30. The parameters
are defined in Table 15-9 on page 15-21.

gfpStatsTxOctets
2
Number of GFP bytes transmitted.
gfpStatsRxSBitErrors Sum of all the single bit errors. In the GFP CORE HDR at the GFP-T
receiver, these are correctable.
gfpStatsRxMBitErrors Sum of all the multiple bit errors. In the GFP CORE HDR at the GFP-T
receiver, these are uncorrectable.
gfpStatsRxTypeInvalid Number of receive packets dropped due to Client Data Frame UPI errors.
gfpStatsRxCIDInvalid
1
Number of packets with invalid CID.
gfpStatsCSFRaised Number of GFP Client signal fail frames detected at the GFP-T receiver.
ifInPayloadCrcErrors
1
Received payload CRC errors.
ifOutPayloadCrcErrors
1
Transmitted payload CRC errors.
hdlcPktDrops Number of received packets dropped before input.
1. Applicable only for CE100T-8
2. Applicable only for CE1000-4
