Performance Monitoring

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds for, and report performance data for early detection of problems. In this chapter, PM parameters and concepts are defined for electrical cards, Ethernet cards, optical cards, multirate cards, storage access networking (SAN) cards, and dense wavelength division multiplexing (DWDM) 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 documents GR-1230-CORE, GR-820-CORE, GR-499-CORE, and GR-253-CORE and the ANSI T1.231 document entitled Digital Hierarchy - Layer 1 In-Service Digital Transmission Performance Monitoring.

5.1  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 SONET thresholds, refer to the Cisco ONS 15454 Procedure Guide.

During the accumulation cycle, if the current value of a PM 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 zero is entered as the threshold value, generation of TCAs is disabled, but performance monitoring continues.

Note Due to limitations of memory and the number of TCAs generated by different platforms, you can manually add/modify the following two properties to the platform property file (CTC.INI for Windows and .ctcrc for UNIX) to fit the need:ctc.15xxx.node.tr.lowater=yyy (where xxx is platform and yyy is the number of the lowater mark. The default lowater mark is 25.)
ctc.15xxx.node.tr.hiwater=yyy (where xxx is platform and yyy is the number of the hiwater mark. The default hiwater mark is 50.)
If the number of the incoming TCA is greater than the hiwater mark, it will keep the latest lowater mark and discard older ones.

Change the threshold if the default value does not satisfy your error monitoring needs. For example, customers with a critical DS-1 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.

5.2  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 networks only use line terminating equipment (LTE), not path terminating equipment (PTE). Table 5-1 shows ONS 15454 cards that are considered LTE.

1 An OC-48 IR card used in a bidirectional line switched ring (BLSR) does not support IPPM during a protection switch.


ONS 15454 Software R3.0 and higher allows LTE cards to monitor near-end PM data on individual synchronous transport signal (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 by all OC-N cards. It is supported by OC3-4 and EC-1 cards. 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.

See Table 5-2 for detailed information and definitions of specific IPPM parameters.

5.3  Pointer Justification Count Performance Monitoring

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 synchronization, jitter and wander occur 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-P) or path-generated (PPJC-PGEN-P) positive pointer justifications. NPJC is a count of path-detected (NPJC-PDET-P) or path-generated (NPJC-PGEN-P) negative pointer justifications depending on the specific PM name. PJCDIFF is the absolute value of the difference between the total number of detected pointer justification counts and the total number of generated pointer justification counts. PJCS-PDET-P is a count of the one-second intervals containing one or more PPJC-PDET or NPJC-PDET. PJCS-PGEN-P is a count of the one-second intervals containing one or more PPJC-PGEN or NPJC-PGEN.

A consistent pointer justification count indicates clock synchronization problems between nodes. A difference between the counts means that 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 5-1 for a list of Cisco ONS 15454 LTE cards. In CTC, the count fields for PPJC and NPJC PMs appear white and blank unless they are enabled on the card view Provisioning tab.

See Table 5-2 for detailed information and definitions of specific pointer justification count PM parameters.

Note Far-end DS1 performance monitoring values are valid only when the DS1 line is set to extended super frame (ESF).

5.5.3.1  DS-1 Facility Data Link Performance Monitoring

Facility Data Link (FDL) performance monitoring enables an ONS 15454 DS1N-14 card to calculate and report DS-1 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 DS-1 FDL PM values, the DS-1 must be set to use ESF format and the FDL must be connected to an intelligent CSU. For procedures for provisioning ESF on the DS1N-14 card, refer to the Cisco ONS 15454 Procedure Guide.

The monitored DS-1 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. See Table 5-2 for detailed information and definitions of specific FDL DS1 PM parameters.

5.6  Performance Monitoring for Ethernet Cards

The following sections define PM parameters and definitions for the ONS 15454 E-Series, G-Series, ML-Series, and CE100T-8 Ethernet cards.

5.6.1  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.

5.6.1.1  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.

Table 5-12 defines the E-Series Ethernet card statistics parameters.

Table 5-12 E-Series Ethernet Statistics Parameters 

Parameter
Definition

Link Status

Indicates whether link integrity is present; 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; alignment errors are received incomplete frames.

Rx Runts

Measures undersized packets with bad cyclic redundancy check (CRC) errors.

Rx Shorts

Measures undersized packets with good CRC errors.

Rx Oversized + Jabbers

Measures oversized packets and jabbers. Size is greater than 1522 errors regardless of CRC errors.

Tx Collisions

Number of transmit packets that are collisions; the port and the attached device transmitting at the same time causes 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 transmissions that are consecutive collisions.

Tx Deferred

Number of transmitted packets deferred.


5.6.1.2  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 drop-down list 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 E-Series Ethernet cards is shown in Table 5-13.

Table 5-13 maxBaseRate for STS Circuits 

STS

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 through the card view Maintenance tab.

5.6.1.3  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 5-14. The parameters are defined in Table 5-12.

5.6.2  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.

5.6.2.1  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 5-15 defines the G-Series Ethernet card statistics parameters.

Table 5-15 G-Series Ethernet Statistics Parameters 

Parameter
Definition

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 FCS error. FCS errors indicate frame corruption during transmission.

Rx Alignment

Number of packets with received incomplete frames.

Rx Runts

Measures undersized packets with bad CRC errors.

Rx Shorts

Measures undersized packets with good CRC errors.

Rx Jabbers

The total number of frames received that exceed the 1548-byte maximum and contain CRC errors.

Rx Giants

Number of packets received that are greater than 1530 bytes in length.

Rx Pause Frames

Number of received Ethernet IEEE 802.3z pause frames.

Tx Pause Frames

Number of transmitted IEEE 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

High-level data link control (HDLC) errors received from SONET/SDH (see Note).

Rx Unicast Packets

Number of unicast packets received since the last counter reset.

Tx Unicast Packets

Number of unicast packets transmitted.

Rx Multicast Packets

Number of multicast packets received since the last counter reset.

Tx Multicast Packets

Number of multicast packets transmitted.

Rx Broadcast Packets

Number of broadcast packets received since the last counter reset.

Tx Broadcast Packets

Number or broadcast packets transmitted.


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 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 HDLC errors. However, the actual values of these counters are less significant than the fact that they are changing.

5.6.2.2  G-Series Ethernet Utilization Window

The Utilization window shows the percentage of Tx and 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 drop-down list 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 Ethernet cards is shown in Table 5-13.

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.

5.6.2.3  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 5-14. The listed parameters are defined in Table 5-15.

5.6.3  ML-Series Ethernet Card Performance Monitoring Parameters

CTC provides Ethernet performance information for line-level parameters and historical Ethernet statistics. The ML-Series Ethernet performance information is divided into the Ether Ports and Packet-over-SONET (POS) Ports tabbed windows within the card view Performance tab window.

5.6.4  CE-Series Ethernet Card Performance Monitoring Parameters

CTC provides Ethernet performance information, including line-level parameters, port bandwidth consumption, and historical Ethernet statistics. The CE-Series card Ethernet performance information is divided into Ether Ports and POS Ports tabbed windows within the card view Performance tab window.

5.6.4.1  CE-Series Card Ether Port Statistics Window

The Ethernet Ether Ports 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 CE-Series Statistics window also has a Clear button. The Clear button sets the values on the card to zero, but does not reset the CE-Series card.

During each automatic cycle, whether auto-refreshed or manually refreshed (using the Refresh button), statistics are added cumulatively and are not immediately adjusted to equal total received packets until testing ends.
