Performance Monitoring


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

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


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 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.


Note Due to limitations of memory and the number of TCAs generated by different platforms, you can manually add or modify the following two properties to their property file (CTC.INI for Windows and .ctcrc for UNIX) to fit the need:
ctc.15xxx.node.tr.lowater=yyy (where xxx is the 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 the platform and yyy is the number of the hiwater mark. The default hiwater mark is 50.)
If the number of 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 E1 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 ONS 15454 SDH networks only use line terminating equipment (LTE), not path terminating equipment (PTE). Table 5-1 shows ONS 15454 SDH cards that are considered LTE.

Software Release 3.0 (R3.0) and later allow LTE cards to monitor near-end PM data on individual high-order paths by enabling IPPM. After enabling IPPM provisioning on the line card, service providers can monitor high-order paths that are configured in pass-through mode on an ONS 15454 SDH operating in SDH AU4 mode, thus making troubleshooting and maintenance activities more efficient.

IPPM occurs only on high-order paths that have IPPM enabled, and TCAs are raised only for PM parameters on the IPPM enabled paths. The monitored IPPM parameters are HP-EB, HP-BBE, HP-ES, HP-SES, HP-UAS, HP-ESR, HP-SESR, and HP-BBER.


Note The E1 card and STM-1 card can monitor far-end IPPM. For all other cards listed in Table 5-1, 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.

5.3  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 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 VC4 payloads. The VC4 payload pointer is located in the H1 and H2 bytes of the AU pointers section and is a count of the number of bytes the VC4 path overhead (POH) J1 byte is away from the H3 byte, not including the section overhead bytes. Clocking differences are measured by the offset in bytes from the pointer to the first byte of the VC4 POH 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 POH is too slow in relation to the rate of the VC4.

You must enable PPJC and NPJC performance monitoring parameters for LTE cards. See Table 5-1 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.

5.6  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.

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. The following sections describe PM parameters provided for the E100T-G and E1000-2 Ethernet cards.

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 5-6 defines the E-Series Ethernet card statistics parameters.

Table 5-6 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

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.

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.


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 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 5-7.

Table 5-7 MaxBaseRate for VC Circuits 

STS

VC3

51840000

VC4

155000000

VC42C

311000000

VC44C

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 5-8. The parameters are defined in Table 5-6.

Table 5-8 Ethernet Statistics History per Time Interval

Number of Intervals Displayed

1 minute

60 previous time intervals

15 minutes

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. The following sections describe PM parameters provided for the G1000-4 and G1K-4 Ethernet cards.

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 5-9 defines the G-Series Ethernet card statistics parameters.

Table 5-9 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 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

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 SDH/SONET.

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.

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.


5.6.2.2  G-Series Ethernet Utilization Window

The Utilization window shows the percentage of Tx and R) 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 VC is shown in Table 5-7.


Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.



Note Unlike E-Series cards, G-Series cards do not have a display of Trunk Utilization statistics, because G-Series cards are not Layer 2 devices.


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 5-8. The parameters are defined in Table 5-9.

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/SDH (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.

5.6.3.1  ML-Series Ether Ports Parameters

The Ether Ports window lists Ethernet PM parameter values for each Ethernet port on the card. Auto-Refresh sets a time interval at which automatic refresh will occur. The PM values are a snapshot captured at the time intervals selected in the Auto-Refresh field. Historical PM values are not stored or displayed.

5.6.4  CE-Series Ethernet Card Performance Monitoring Parameters

CTC provides Ethernet performance information for line-level parameters and historical Ethernet statistics. The CE-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 CE-100T-8 Ethernet card.

5.6.4.1  CE-Series Ether Ports Statistics Parameters

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. To see the final PM count totals, allow a few moments for the PM window statistics to finish testing and update fully. PM counts are also listed in the CE-Series card Performance > History window.

Table 5-13 defines the CE-Series Ethernet card Ether Ports PM parameters.

5.6.4.2  CE-Series Card Ether Ports Utilization Parameters

The Ether Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the Ethernet ports during consecutive time segments. 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 CE-Series Ethernet cards is shown in Table 5-7.

5.6.4.3  CE-Series Card Ether Ports History Parameters

The Ethernet Ether Ports 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 5-8. The parameters are those defined in Table 5-13.

5.6.4.4  CE-Series POS Ports Statistics Parameters

The Ethernet POS Ports statistics window lists Ethernet POS parameters at the line level. Table 5-14 defines the CE-Series Ethernet card POS Ports parameters.

5.6.4.5  CE-Series Card POS Ports Utilization Parameters

The POS Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the POS ports during consecutive time segments. 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 * 8) / (interval * maxBaseRate)

Tx = (outOctets * 8) / (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 CE-Series cards is shown in Table 5-7.


Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.


5.6.4.6  CE-Series Card Ether Ports History Parameters

The Ethernet POS Ports History window lists past Ethernet POS Ports 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 5-8.

5.7  Performance Monitoring for Optical Cards

The following sections define performance monitoring parameters and definitions for the OC3 IR 4/STM1 SH 1310 card, the OC3 IR/STM1 SH 1310-8 card, the OC12 IR/STM4 SH 1310, OC12 LR/STM4 LH 1310 card, the OC12 LR/STM4 LH 1550 card, the OC12 IR/STM4 SH 1310-4 card, the OC48 IR/STM16 SH AS 1310 card, OC48 LR/STM16 LH AS 1550 card, the OC48 ELR/STM16 EH 100 GHz card, the OC192 SR/STM64 IO 1310 card, the OC192 IR/STM64 SH 1550 card, OC192 LR/STM 64 LH 1550 card, the OC192 LR/STM64 LH ITU 15xx.xx, OC192 SR1/STM64IO Short Reach card, and the OC192/STM64 Any Reach card.

On all STM-N optical cards, errors are calculated in bits instead of blocks for B1 and B3. This means there could possibly be a slight difference between what is inserted and what is reported on CTC. In STM4, for example, there are approximately 15,000 to 30,000 bits per block (per ITU-T-G.826). If there were two bit errors within that block, the standard would require reporting one block error whereas the STM-N cards would have reported two bit errors.

When a tester inputs only single errors during testing, this issue would not appear because a tester is not fast enough to induce two errors within a single block. However, if the test is performed with an error rate, certain error rates could cause two or more errors in a block. For example, since the STM4 is roughly 622 Mbps and the block in the STM4 has 15,000 bits, there would be about 41,467 blocks in a second. If the tester inputs a 10e-4 error rate, that would create 62,200 errors per second. If the errors are distributed uniformly, then CTC could potentially report two bit errors within a single block. On the other hand, if the error ratio is 10e-5, then there will be 6,220 errors per second. If the errors are not distributed uniformly, then CTC might report one bit error within a single block. In summary, if the errors are distributed equally, then a discrepancy with the standard might be seen when a tester inputs 10e-4 or 10e-3 error rates.

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 * 24) * 8 / 100% interval * maxBaseRate

Tx = (outOctets + outPkts * 24) * 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 or 2 Gbps). The maxBaseRate for FC_MR-4 cards is shown in Table 5-25.

1 For 1 Gigabit of bit rate being transported, there is only 850 Mbps of actual data because of 8b->10b conversion. Similarly, for 2 G of bit rate being transported there is only 850 Mbps x 2 of actual data.



Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.


5.9.1.3  FC_MR-4 History Window

The History window lists past FC_MR-4 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 5-26. The parameters are defined in Table 5-8.
