Performance monitoring parameters (PMs) are used by service providers to gather, store, threshold, 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.
For information about enabling and viewing PM values, refer to the Cisco ONS 15454 Procedure Guide.
Note For additional information regarding PM parameters, refer to Telcordia's GR-1230-CORE, GR-820-CORE, GR-499-CORE, and GR-253-CORE documents and the ANSI document entitled Digital Hierarchy - Layer 1 In-Service Digital Transmission Performance Monitoring.
12.1 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 Provisioningtab. For procedures on provisioning card thresholds, such as line, path, and SONET thresholds, refer to the Cisco ONS 15454 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.
12.2 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 networks only use line terminating equipment (LTE) not path terminating equipment (PTE). Table 12-1 shows ONS 15454 cards that are considered LTEs.

Software 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 which 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, SONET path PMs can be monitored by logging into the far-end node directly.
The ONS 15454 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.
Pointers are used to compensate for frequency and phase variations. Pointer justification counts indicate timing errors on SONET networks. When a network is out of synch, 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 12-1 for a list of Cisco ONS 15454 LTE cards. On CTC, the count fields for PPJC and NPJC PMs 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.
12.4 DS1 Facility Data Link Performance Monitoring
Facility Data Link (FDL) performance monitoring enables the DS1N-14 card to calculate and report DS1 error rate performance measured at both the near-end and far-end of the FDL. The far-end information is reported as received on the FDL in a performance report message (PRM) from an intelligent channel service unit (CSU).
To monitor DS1 FDL PM values, the DS1 must be set to use extended superframe (ESF) format and the FDL must be connected to an intelligent CSU. For procedures on provisioning ESF on the DS1N-14 card, refer to the Cisco ONS 15454 Procedure Guide.
The monitored DS1 FDL PM parameters are, CV-PFE, ES-PFE, ESA-PFE, ESB-PFE, SES-PFE, SEFS-PFE, CSS-PFE, UAS-PFE, FC-PFE, and ES-LFE. For detailed information about specific DS1 FDL PM parameters, locate the DS1N-14 card name in the following sections and review the appropriate definition.

12.6 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.
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 panes within the card view Performance tab window.
12.6.1.1 E-Series Ethernet Statistics Pane
The Ethernet statistics pane lists Ethernet parameters at the line level. The Statistics pane provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refreshbutton manually refreshes statistics. Auto-Refreshsets a time interval at which automatic refresh will occur.
Table 12-35 defines the E-Series Ethernet card Statistics parameters.

Rx Giants
Number of packets received that are greater than 1518 bytes in length for untagged interfaces and 1522 bytes for tagged interfaces
Tx Collisions
Number of transmit packets that are collisions; the port and the attached device transmitting at the same time caused collisions
Tx Late Collisions
Number of frames that were not transmitted since they encountered a collision outside of the normal collision window (late collision events should occur only rarely).
Tx Excessive Collisions
Number of consecutive collisions
Tx Deferred
Number of packets deferred
12.6.1.2 E-Series Ethernet Utilization Pane
The Utilization pane 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 auto-negotiate 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 pane 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:
The interval is defined in seconds. The maxBaseRate is defined by raw bits/second in one direction for the Ethernet port (that is, 1 Gbps). The maxBaseRates for E-series Ethernet cards is shown in Table 12-36.
Table 12-36 maxBaseRate for STS Circuits

STS-3c
155000000
STS-6c
311000000
STS-12c
622000000
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.
12.6.1.3 E-Series Ethernet History Pane
The Ethernet History pane lists past Ethernet statistics for the previous time intervals. Depending on the selected time interval, the History pane will display the statistics for each port for the number of previous time intervals as shown in Table 12-37. The listed parameters are defined in Table 12-35.

12.6.2.1 G-Series Ethernet Statistics Pane
The Ethernet statistics pane lists Ethernet parameters at the line level. The Statistics pane provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refreshbutton manually refreshes statistics. Auto-Refreshsets a time interval at which automatic refresh will occur. The G-Series Statistics pane also has a Clear button. The Clearbutton sets the values on the card to zero, but will not reset the G-Series card.
Table 12-38 defines the G-Series Ethernet card Statistics parameters.
A time stamp indicating the last time statistics were reset.
Link Status
Indicates whether the Ethernet link is receiving a valid Ethernet signal (carrier) from the attached Ethernet device; up means present, and down means not present

Number of bytes transmitted since the last counter reset
Rx Total Errors
Total number of receive errors
Rx FCS
Number of packets with a Frame Check Sequence (FCS) error. FCS errors indicate frame corruption during transmission
Rx Alignment
Number of packets with received incomplete frames
Rx Runts
The total number of frames received that are less than 64 bytes in length and have a CRC error
Rx Jabbers
The total number of frames received that exceed the1548-byte maximum and contain CRC errors

Rx Pkts Dropped Internal Congestion
Number of received packets dropped due to overflow in G-Series frame buffer
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 SONET/SDH (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 SONET path problems should be present, it might indicate a problem with the quality of the SONET path. For example, a SONET protection switch generates a set of HLDC errors. But the actual values of these counters are less significant than the fact they are changing.
12.6.2.2 G-Series Ethernet Utilization Pane
The Utilization pane 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 auto-negotiate 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 pane 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:
The interval is defined in seconds. The maxBaseRate is defined by raw bits/second in one direction for the Ethernet port (that is,1 Gbps). The maxBaseRates for G-series Ethernet cards is shown in Table 12-39.
Table 12-39 maxBaseRate for STS Circuits
STS-1
51840000
STS-3c
155000000
STS-6c
311000000
STS-12c
622000000
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.
12.6.2.3 G-Series Ethernet History Pane
The Ethernet History pane lists past Ethernet statistics for the previous time intervals. Depending on the selected time interval, the History pane will display the statistics for each port for the number of previous time intervals as shown in Table 12-40. The listed parameters are defined in Table 12-38.
Table 12-40 Ethernet History Statistics per Time Interval

Near-End Line Code Violation (CV-L) is a count of BIP errors detected at the line-layer (i.e. using the B2 bytes in the incoming SONET signal). Up to 8 x N BIP errors can be detected per STS-N frame; each error increments the current CV-L second register.
ES-L
Near-End Line Errored Seconds (ES-L) is a count of the seconds when at least one line-layer BIP error was detected or an AIS-L defect was present.
SES-L
Near-End Line Severely Errored Seconds (SES-L) is a count of the seconds when K (see GR-253 for values) or more line-layer BIP errors were detected or an AIS-L defect was present.
UAS-L
Near-End Line Unavailable Seconds (UAS-L) is a count of the seconds when the line is unavailable. A line becomes unavailable when ten consecutive seconds occur that qualify as SES-Ls, and it continues to be unavailable until ten consecutive seconds occur that do not qualify as SES-Ls.
FC-L
Near-End Line Failure Count (FC-L) is a count of the number of near-end line failure events. A failure event begins when an AIS-L failure or a lower-layer traffic-related, near-end failure is declared. This failure event ends when the failure is cleared. A failure event that begins in one period and ends in another period is counted only in the period where it begins.

PSC (BLSR)
For a protect line in a 2-fiber ring, Protection Switching Count (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 2-fiber BLSR, the 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 PSC of the protect span will increment again.
PSC (1+1 protection)
In a 1 + 1 protection scheme for a working card, Protection Switching Count (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, 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 PSC PM is only applicable if revertive line-level protection switching is used.
PSD
For an active protection line in a 2-fiber BLSR, Protection Switching Duration (PSD) is a count of the number of seconds that the protect line is carrying working traffic following the failure of the working line. PSD increments on the active protect line and PSD-W increments on the failed working line.
PSC-W
For a working line in a 2-fiber BLSR, Protection Switching Count-Working (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. PSC-W increments on the failed working line and PSC increments on the active protect line.
For a working line in a 4-fiber BLSR, 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. PSC-W increments on the failed line and PSC-R or PSC-S increments on the active protect line.
PSD-W
For a working line in a 2-fiber BLSR, Protection Switching Duration-Working (PSD-W) is a count of the number of seconds that service was carried on the protection line. PSD-W increments on the failed working line and PSD increments on the active protect line.
PSC-S
In a 4-fiber BLSR, Protection Switching Count-Span (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.
PSD-S
In a 4-fiber BLSR, Protection Switching Duration-Span (PSD-S) is a count of the seconds that the protection line was used to carry service. A count is only incremented if span switching is used.
PSC-R
In a 4-fiber BLSR, Protection Switching Count-Ring (PSC-R) 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 a working line. A count is only incremented if ring switching is used.
PSD-R
In a 4-fiber BLSR, Protection Switching Duration-Ring (PSD-R) is a count of the seconds that the protection line was used to carry service. A count is only incremented if ring switching is used.

Near-End STS Path Coding Violations (CV-P) is a count of BIP errors detected at the STS path layer (i.e., using the B3 byte). Up to eight BIP errors can be detected per frame; each error increments the current CV-P second register.
STS ES-P
Near-End STS Path Errored Seconds (ES-P) is a count of the seconds when at least one STS path BIP error was detected. An AIS-P defect (or a lower-layer, traffic-related, near-end defect) or an LOP-P defect can also cause an STS ES-P.
STS FC-P
Near-End STS Path Failure Counts (FC-P) is a count of the number of near-end STS path failure events. A failure event begins with an AIS-P failure, an LOP-P failure, a UNEQ-P failure or a TIM-P failure is declared, or if the STS PTE that is monitoring the path supports ERDI-P for that path. The failure event ends when these failures are cleared.
STS SES-P
Near-End STS Path Severely Errored Seconds (SES-P) is a count of the seconds when K (2400) or more STS path BIP errors were detected. An AIS-P defect (or a lower-layer, traffic-related, near-end defect) or an LOP-P defect can also cause an STS SES-P.
STS UAS-P
Near-End STS Path Unavailable Seconds (UAS-P) is a count of the seconds when the STS path was unavailable. An STS path becomes unavailable when ten consecutive seconds occur that qualify as SES-Ps, and it continues to be unavailable until ten consecutive seconds occur that do not qualify as SES-Ps.
