Performance Monitoring


Performance monitoring (PM) parameters 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 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


Note For additional information regarding PM parameters, refer to ITU G.826, Telcordia's GR-820-CORE, GR-499-CORE, and GR-253-CORE documents.


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 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.

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 SDH networks only use line terminating equipment (LTE) not path terminating equipment (PTE). Table 12-1 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 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, 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.

12.3 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 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 SDH LTE cards. On 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.

12.5 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.

12.5.1 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.

12.5.1.1 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 will occur.

Table 12-15 defines the E-Series Ethernet card Statistics parameters.

Table 12-15 E-Series Ethernet Statistics Parameters 

Parameter
Meaning

Link Status

Link integrity indicator (up means present, and down means not present).

Rx Packets

Number of packets received since the last counter reset.

Rx Bytes

Number of bytes received since the last counter reset.

Tx Packets

Number of packets transmitted since the last counter reset.

Tx Bytes

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 alignment errors (received incomplete frames).

Rx Runts

Number of packets received that are less than 64 bytes in length.

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. Normally, late collision events should occur only rarely, if at all.

Tx Excessive Collisions

Number of consecutive collisions.

Tx Deferred

Number of packets deferred.


12.5.1.2 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 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 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/second in one direction for the Ethernet port (i.e. 1 Gbps). STS circuit maxBaseRates are shown in Table 12-16.

Table 12-16 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 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.


12.5.1.3 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 will display the statistics for each port for the number of previous time intervals as shown in Table 12-17. The listed parameters are defined in Table 12-15.

12.5.2 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.

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 will occur. The G-Series Statistics window also has a Clear button. The Clear button sets the values on the card to zero, but will not reset the G-Series card.

Table 12-18 defines the G-Series Ethernet card Statistics parameters.

Table 12-18 G-Series Ethernet Statistics Parameters 

Parameter
Meaning

Time Last Cleared

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.

Rx Packets

Number of packets received since the last counter reset.

Rx Bytes

Number of bytes received since the last counter reset.

Tx Packets

Number of packets transmitted since the last counter reset.

Tx Bytes

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

Total number of frames received that are less than 64 bytes in length and have a CRC error.

Rx Jabbers

Total number of frames received that exceed the1548-byte maximum and contain CRC errors.

Rx Pause Frames

Number of received Ethernet 802.3z pause frames.

Tx Pause Frames

Number of transmitted 802.3z pause frames.

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

HDLC errors received from SDH/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 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.


12.5.2.2 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 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 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/second in one direction for the Ethernet port (i.e. 1 Gbps). The maxBaseRate for G-series STS is shown in Table 12-19.

Table 12-19 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.


12.5.2.3 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 will display the statistics for each port for the number of previous time intervals as shown in Table 12-20. The listed parameters are defined in Table 12-18.

The ML-Series Ethernet performance information is divided into the Ether Ports and POS Ports tabbed windows within the card view Performance tab window. The following sections describe PM parameters provided for the ML100T-12 and ML1000-2 Ethernet cards.

Definition

MS-PSC1 (MS-SPRing)

For a protect line in a 2-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 2-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.

MS-PSC (1+1 protection)

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 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 2-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. PSC-W increments on the failed working line and PSC increments on the active protect line.

MS-PSD-W

For a working line in a 2-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 PSD increments on the active protect line.
