Performance Monitoring
Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds, and report performance data for early detection of problems. In this chapter, PM parameters and concepts are defined for electrical cards, Ethernet cards, and optical cards in the Cisco ONS 15454 SDH.
For information about enabling and viewing PM values, refer to the Cisco ONS 15454 SDH Procedure Guide.
Chapter topics include:
•Threshold Performance Monitoring
•Intermediate-Path Performance Monitoring
•Pointer Justification Count Performance Monitoring
•Performance Monitoring for Electrical Cards
•Performance Monitoring for Ethernet Cards
•Performance Monitoring for Optical Cards
•Performance Monitoring for DWDM Cards
Note For additional information regarding PM parameters, refer to ITU G.826, Telcordia documents GR-820-CORE, GR-499-CORE, and GR-253-CORE.
15.1 Threshold Performance Monitoring
Thresholds are used to set error levels for each PM parameter. You can set individual PM threshold values from the Cisco Transport Controller (CTC) card view Provisioning tab. For procedures on provisioning card thresholds, such as line, path, and SDH thresholds, refer to the Cisco ONS 15454 SDH Procedure Guide.
During the accumulation cycle, if the current value of a performance monitoring parameter reaches or exceeds its corresponding threshold value, a threshold crossing alert (TCA) is generated by the node and displayed by CTC. TCAs provide early detection of performance degradation. When a threshold is crossed, the node continues to count the errors during a given accumulation period. If 0 is entered as the threshold value, the performance monitoring parameter is disabled.
Change the threshold if the default value does not satisfy your error monitoring needs. For example, customers with a critical DS1 installed for 911 calls must guarantee the best quality of service on the line; therefore, they lower all thresholds so that the slightest error raises a TCA.
15.2 Intermediate-Path Performance Monitoring
Intermediate-path performance monitoring (IPPM) allows transparent monitoring of a constituent channel of an incoming transmission signal by a node that does not terminate that channel. Many large ONS 15454 SDH networks only use line terminating equipment (LTE) not path terminating equipment (PTE). Table 15-1 shows ONS 15454 SDH cards that are considered LTEs.

Software Release 3.0 (R3.0) and higher allows LTE cards to monitor near-end PM data on individual STS payloads by enabling IPPM. After enabling IPPM provisioning on the line card, service providers can monitor large amounts of STS traffic through intermediate nodes, thus making troubleshooting and maintenance activities more efficient.
IPPM occurs only on STS paths that have IPPM enabled, and TCAs are raised only for PM parameters on the IPPM enabled paths. The monitored IPPM parameters are STS CV-P, STS ES-P, STS SES-P, STS UAS-P, and STS FC-P.
Note Far-end IPPM is not supported. However, SDH path PM parameters can be monitored by logging into the far-end node directly.
The ONS 15454 SDH performs IPPM by examining the overhead in the monitored path and by reading all of the near-end path PM values in the incoming direction of transmission. The IPPM process allows the path signal to pass bidirectionally through the node completely unaltered.
For detailed information about specific IPPM parameters, locate the card name in the following sections and review the appropriate definition.
15.3 Pointer Justification Count Performance Monitoring
Pointers are used to compensate for frequency and phase variations. Pointer justification counts indicate timing errors on SDH networks. When a network is out of sync, jitter and wander occurs on the transported signal. Excessive wander can cause terminating equipment to slip.
Slips cause different effects in service. Voice service has intermittent audible clicks. Compressed voice technology has short transmission errors or dropped calls. Fax machines lose scanned lines or experience dropped calls. Digital video transmission has distorted pictures or frozen frames. Encryption service loses the encryption key causing data to be transmitted again.
Pointers provide a way to align the phase variations in STS and VT payloads. The STS payload pointer is located in the H1 and H2 bytes of the line overhead. Clocking differences are measured by the offset in bytes from the pointer to the first byte of the STS synchronous payload envelope (SPE) called the J1 byte. Clocking differences that exceed the normal range of 0 to 782 can cause data loss.
There are positive (PPJC) and negative (NPJC) pointer justification count parameters. PPJC is a count of path-detected (PPJC-Pdet) or path-generated (PPJC-Pgen) positive pointer justifications. NPJC is a count of path-detected (NPJC-Pdet) or path-generated (NPJC-Pgen) negative pointer justifications depending on the specific PM name.
A consistent pointer justification count indicates clock synchronization problems between nodes. A difference between the counts means the node transmitting the original pointer justification has timing variations with the node detecting and transmitting this count. Positive pointer adjustments occur when the frame rate of the SPE is too slow in relation to the rate of the STS 1.
You must enable PPJC and NPJC performance monitoring parameters for LTE cards. See Table 15-1 for a list of Cisco ONS 15454 SDH LTE cards. In CTC, the count fields for PPJC and NPJC PM parameters appear white and blank unless they are enabled on the card view Provisioning tab.
For detailed information about specific pointer justification count PM parameters, locate the card name in the following sections and review the appropriate definition.

15.5 Performance Monitoring for Ethernet Cards
The following sections define performance monitoring parameters and definitions for the E-Series, G-Series, and ML-Series Ethernet cards.
15.5.1 E-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth consumption, and historical Ethernet statistics. The E-Series Ethernet performance information is divided into the Statistics, Utilization, and History tabbed windows within the card view Performance tab window. The following sections describe PM parameters provided for the E100T-G and E1000-2 Ethernet cards.
15.5.1.1 E-Series Ethernet Statistics Window
The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic refresh occurs.

15.5.1.2 E-Series Ethernet Utilization Window
The Utilization window shows the percentage of transmit (Tx) and receive (Rx) line bandwidth used by the Ethernet ports during consecutive time segments. The Mode field displays the real-time mode status, such as 100 Full, which is the mode setting configured on the E-Series port. However, if the E-Series port is set to autonegotiate the mode (Auto), this field shows the result of the link negotiation between the E-Series and the peer Ethernet device attached directly to the E-Series port.
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 + 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 Ethernet port (that is, 1 Gbps). STS circuit maxBaseRates are shown in Table 15-16.

Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note The E-Series Ethernet card is a Layer 2 device or switch and supports Trunk Utilization statistics. The Trunk Utilization statistics are similar to the Line Utilization statistics, but shows the percentage of circuit bandwidth used rather than the percentage of line bandwidth used. The Trunk Utilization statistics are accessed via the card view Maintenance tab.
15.5.1.3 E-Series Ethernet History Window
The Ethernet History window lists past Ethernet 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 15-17. The listed parameters are defined in Table 15-15.

15.5.2 G-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth consumption, and historical Ethernet statistics. The G-Series Ethernet performance information is divided into the Statistics, Utilization, and History tabbed windows within the card view Performance tab window. The following sections describe PM parameters provided for the G1000-4 and G1K-4 Ethernet cards.
15.5.2.1 G-Series Ethernet Statistics Window
The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic refresh occurs. The G-Series Statistics window also has a Clear button. The Clear button sets the values on the card to zero, but does not reset the G-Series card.
Table 15-18 defines the G-Series Ethernet card Statistics parameters.

|
Tx Pkts Dropped Internal Congestion
|
Number of transmit queue drops due to drops in the G-Series frame buffer.
|
HDLC Errors
|
High-level data link control (HDLC) errors received from SDH/SONET (see note).
|
Note Do not use the HDLC errors counter to count the number of frames dropped because of HDLC errors, because each frame can fragment into several smaller frames during HDLC error conditions and spurious HDLC frames can also be generated. If HDLC error counters are incrementing when no SDH path problems should be present, it might indicate a problem with the quality of the SDH path. For example, a SDH protection switch generates a set of HLDC errors. But the actual values of these counters are less significant than the fact they are changing.
15.5.2.2 G-Series Ethernet Utilization Window
The Utilization window shows the percentage of transmit (Tx) and receive (Rx) line bandwidth used by the Ethernet ports during consecutive time segments. The Mode field displays the real-time mode status, such as 100 Full, which is the mode setting configured on the G-Series port. However, if the G-Series port is set to autonegotiate the mode (Auto), this field shows the result of the link negotiation between the G-Series and the peer Ethernet device attached directly to the G-Series port.
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 + 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 Ethernet port (that is, 1 Gbps). The maxBaseRate for G-series STS is shown in Table 15-19.

Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note Unlike the E-Series, the G Series card does not have a display of Trunk Utilization statistics, because the G-Series card is not a Layer 2 device or switch.
15.5.2.3 G-Series Ethernet History Window
The Ethernet History window lists past Ethernet 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 15-20. The listed parameters are defined in Table 15-18.

MS-PSC (MS-SPRing)
|
For a protect line in a two-fiber ring, Multiplex Section Protection Switching Count (MS-PSC) refers to the number of times a protection switch has occurred either to a particular span's line protection or away from a particular span's line protection. Therefore, if a protection switch occurs on a two-fiber MS-SPRing, the MS-PSC of the protection span to which the traffic is switched will increment, and when the switched traffic returns to its original working span from the protect span, the MS-PSC of the protect span will increment again.
|

|
In a 1+1 protection scheme for a working card, Multiplex Section Protection Switching Count (MS-PSC) is a count of the number of times service switches from a working card to a protection card plus the number of times service switches back to the working card.
For a protection card, MS-PSC is a count of the number of times service switches to a working card from a protection card plus the number of times service switches back to the protection card. The MS-PSC PM is only applicable if revertive line-level protection switching is used.
|
MS-PSD
|
For an active protection line in a two-fiber MS-SPRing, Multiplex Section Protection Switching Duration (MS-PSD) is a count of the number of seconds that the protect line is carrying working traffic following the failure of the working line. MS-PSD increments on the active protect line and MS-PSD-W increments on the failed working line.

MS-PSC-W
|
For a working line in a two-fiber MS-SPRing, Multiplex Section Protection Switching Count-Working (MS-PSC-W) is a count of the number of times traffic switches away from the working capacity in the failed line and back to the working capacity after the failure is cleared. MS-PSC-W increments on the failed working line and MS-PSC increments on the active protect line.
For a working line in a four-fiber MS-SPRing, MS-PSC-W is a count of the number of times service switches from a working line to a protection line plus the number of times it switches back to the working line. MS-PSC-W increments on the failed line and MS-PSC-R or MS-PSC-S increments on the active protect line.
|
MS-PSD-W
|
For a working line in a two-fiber MS-SPRing, Multiplex Section Protection Switching Duration-Working (MS-PSD-W) is a count of the number of seconds that service was carried on the protection line. MS-PSD-W increments on the failed working line and MS-PSD increments on the active protect line.
|
MS-PSC-S
|
In a four-fiber MS-SPRing, Multiplex Section Protection Switching Count-Span (MS-PSC-S) is a count of the number of times service switches from a working line to a protection line plus the number of times it switches back to the working line. A count is only incremented if span switching is used.
|
MS-PSD-S
