17.2.2.3 MXP_MR_2.5G/MXPP_MR_2.5G Payload Utilization Window

The Payload PM Utilization window in the card view Performance > Payload> Utilization tab shows the
percentage of transmit (Tx) and receive (Rx) line bandwidth used by the ports during consecutive time
segments. This tab cannot be viewed unless the appropriate PPM port type is provisioned. For PPM
provisioning procedures, refer to the Cisco ONS 15454 DWDM Procedure Guide. The Utilization
window provides an Interval list that enables you to set time intervals of 15 minutes or 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 port (that is, 1 Gbps). The maxBaseRate for MXP_MR_2.5G and MXPP_MR_2.5G cards is
shown for the ONS 15454 nodes in
Table 17-9
STS/VC
STS-1/VC3
STS-3c/VC4
STS-6c/VC4-2c
STS-12c/VC4-4c
Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note
17.2.2.4 Payload History Window
The Payload PM History window in the card view Performance > Payload > History tab lists past
statistics for the previous time intervals. This tab cannot be viewed unless the appropriate PPM port type
is provisioned. For PPM provisioning procedures, refer to the Cisco ONS 15454 DWDM Procedure
Guide. 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 17-10

1 day (24 hours)
17.2.3 OTN PM Window
The OTN tab has an ITU-T G.709 PM subtab and an FEC PM subtab. Both subtabs provide buttons to
change the statistical values shown in the Performance tab. The Refresh button manually refreshes
statistics. Auto-Refresh sets a time interval at which automatic refresh occurs. The Baseline button resets
the displayed statistics values to zero. The Statistics window also has a Clear button. The Clear button
