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, optical multirate cards, and storage access networking (SAN) cards in the Cisco ONS 15454.

For information about enabling and viewing PM values, refer to the Cisco ONS 15454 Procedure Guide.

Note For information on PM parameters for Transponder and Muxponder cards, and DWDM cards, refer to Cisco ONS 15454 DWDM Reference Manual.

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.

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 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.

When TCAs occur, CTC displays them. An example is T-UASP-P in the Cond column (shown in Figure 15-1), where the "T-" indicates a threshold crossing. In addition, for certain electrical cards, "RX" or "TX" is appended to the TCA description, as shown (see red circles). The RX indicates that the TCA is associated with the receive direction, and TX indicates the TCA is associated with the transmit direction.

Figure 15-1 TCAs Displayed in CTC

The ONS 15454 SONET electrical cards for which RX and TX are detected and appended to the TCA descriptions are shown in Table 15-1.

Table 15-1 Electrical Cards that Report RX and TX Direction for TCAs
Card	Line				Path
	Near End		Far End		Near End		Far End
	RX	TX	RX	TX	RX	TX	RX	TX
DS1-14	YES	—	YES	—	YES	YES	YES	—
DS1N-14	YES	—	YES	—	YES	YES	YES	—

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.

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 networks only use line terminating equipment (LTE), not path terminating equipment (PTE). Table 15-2 shows ONS 15454 cards that are considered LTE.

¹An 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 15-3 for detailed information and definitions of specific IPPM parameters.

15.3 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 15-2 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 15-3 for detailed information and definitions of specific pointer justification count PM parameters.

15.5 Performance Monitoring for Electrical Cards

The following sections define PM parameters for the EC1-12, DS1/E1-56, DS1-14, DS1N-14, DS3-12, DS3-12E, DS3N-12, DS3N-12E, DS3i-N-12, DS3XM-6, DS3XM-12, and DS3/EC1-48 cards.

15.5.1 EC1-12 Card Performance Monitoring Parameters

Figure 15-2 shows signal types that support near-end and far-end PMs. Figure 15-3 shows where overhead bytes detected on the application specific integrated circuits (ASICs) produce PM parameters for the EC1-12 card.

Figure 15-2 Monitored Signal Types for the EC1-12 Card

Note The XX in Figure 15-2 represents all PMs listed in Table 15-4 with the given prefix and/or suffix.

Figure 15-3 PM Read Points on the EC1-12 Card

Table 15-4 lists the PM parameters for the EC1-12 cards.

Table 15-4 EC1-12 Card PMs
Section (NE)	Line (NE)	STS Path (NE)	Line (FE)	STS Path (FE)
CV-S ES-S SES-S SEF-S	CV-L ES-L SES-L UAS-L FC-L	CV-P ES-P SES-P UAS-P FC-P PPJC-PDET-P NPJC-PDET-P PPJC-PGEN-P NPJC-PGEN-P PJCS-PDET-P PJCS-PGEN-P PJC-DIFF-P	CV-LFE ES-LFE SES-LFE UAS-LFE FC-LFE	CV-PFE ES-PFE SES-PFE UAS-PFE FC-PFE

Note If the CV-L(NE and FE) falls in the range 51-61 for EC1,then, the user might see discrepancy in the SES and the UAS-L values. However, ES-L will be in the nearest accuracy. For a few seconds, in a given 10 seconds interval, the number of CV-L counted may not cross the CV count criteria for SES, (due to system/application limitation for the below mentioned ranges) ;as a consequence of which there may not be 10 continuous SES, thus UAS will not be observed.

15.5.2 DS1_E1_56 Card Performance Monitoring Parameters

Figure 15-4 shows signal types that support near-end and far-end PMs.

Figure 15-4 Monitored Signal Types for the DS1/E1-56 Card

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

15.5.3.1 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 15-3 for detailed information and definitions of specific FDL DS1 PM parameters.

Note If the CV-L(NE and FE) falls in the range 51-61 for DS3,then, the user might see discrepancy in the SES and the UAS-L values. However, ES-L will be in the nearest accuracy. For a few seconds, in a given 10 seconds interval, the number of CV-L counted may not cross the CV count criteria for SES, (due to system/application limitation for the below mentioned ranges); as a consequence of which there may not be 10 continuous SES, thus UAS will not be observed.

15.6 Performance Monitoring for Ethernet Cards

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

15.6.1 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.

15.6.1.1 E-Series Ethernet Statistics Window

Table 15-13 defines the E-Series Ethernet card statistics parameters.

Table 15-13 E-Series Ethernet Statistics Parameters
Parameter	Definition
Link Status	Indicates whether link integrity is present; up means present, and down means not present.
ifInOctets	Number of bytes received since the last counter reset.
ifInUcastPkts	Number of unicast packets received since the last counter reset.
ifInErrors	The number of inbound packets (or transmission units) that contained errors preventing them from being deliverable to a higher-layer protocol.
ifOutOctets	Number of bytes transmitted since the last counter reset.
ifOutUcastPkts	Number of unicast packets transmitted.
dot3StatsAlignmentErrors	A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.
dot3StatsFCSErrors	A count of frames received on a particular interface that are an integral number of octets in length but do not pass the FCS check.
dot3StatsFrameTooLong	A count of frames received on a particular interface that exceed the maximum permitted frame size.

etherStatsFragments	The total number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) and had either a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error). Note It is entirely normal for etherStatsFragments to increment. This is because it counts both runts (which are normal occurrences due to collisions) and noise hits.
etherStatsPkts64Octets	The total number of packets (including bad packets) received that were 64 octets in length (excluding framing bits but including FCS octets).
etherStatsPkts65to127 Octets	The total number of packets (including bad packets) received that were between 65 and 127 octets in length inclusive (excluding framing bits but including FCS octets).
etherStatsPkts128to255 Octets	The total number of packets (including bad packets) received that were between 128 and 255 octets in length inclusive (excluding framing bits but including FCS octets).
etherStatsPkts256to511 Octets	The total number of packets (including bad packets) received that were between 256 and 511 octets in length inclusive (excluding framing bits but including FCS octets).

etherStatsJabbers	The total number of packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets), and had either a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error).
etherStatsOctets	The total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets
etherStatsCRCAlign Errors	The total number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had either a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error).

15.6.1.2 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 15-14.

Table 15-14 maxBaseRate for STS Circuits
STS	maxBaseRate
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 through the card view Maintenance tab.

15.6.1.3 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 15-15. The parameters are defined in Table 15-13.

Table 15-15 Ethernet History Statistics per Time Interval
Time Interval	Number of Previous Intervals Displayed
1 minute	60
15 minutes	32
1 hour	24
1 day (24 hours)	7

15.6.2 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.

15.6.2.1 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 15-16 defines the G-Series Ethernet card statistics parameters.

Table 15-16 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.

15.6.2.2 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.

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 15-14.

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.

15.6.2.3 G-Series Ethernet History Window

15.6.3 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.

15.6.4 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.

15.6.4.1 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. 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 15-20 defines the CE-Series card Ethernet port parameters.

Table 15-20 CE-Series Ether Port PM Parameters

15.6.4.2 CE-Series Card Ether Ports Utilization Window

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 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 CE-Series Ethernet cards is shown in Table 15-14.

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

15.6.4.3 CE-Series Card Ether Ports History Window

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 15-15.

15.7 Performance Monitoring for Optical Cards

This section lists PM parameters for ONS 15454 optical cards, including the OC-3, OC-12, OC-48, and OC-192 cards. Figure 15-20 shows the signal types that support near-end and far-end PMs.

Figure 15-20 Monitored Signal Types for the OC-3 Cards

Note The XX in Figure 15-20 represents all PMs listed in Table 15-22, Table 15-23, and Table 15-24 with the given prefix and/or suffix.

Figure 15-21 shows where overhead bytes detected on the ASICs produce PM parameters for the OC3 IR 4 SH 1310 and OC3 IR SH 1310-8 cards.

Note If the CV-L(NE and FE) falls in a specific range, then, the user might see discrepancy in the SES and the UAS-L values. However, ES-L will be in the nearest accuracy. For a few seconds, in a given 10 seconds interval, the number of CV-L counted may not cross the CV count criteria for SES, (due to system/application limitation for the below mentioned ranges); as a consequence of which there may not be 10 continuous SES, thus UAS will not be observed. The corresponding (error) range for the line rates is as shown in Table 15-25.

15.9 Performance Monitoring for Storage Access Networking Cards

The following sections define PM parameters and definitions for the SAN card, also known as the FC_MR-4 or Fibre Channel card.

CTC provides FC_MR-4 performance information, including line-level parameters, port bandwidth consumption, and historical statistics. The FC_MR-4 card performance information is divided into the Statistics, Utilization, and History tabbed windows within the card view Performance tab window.

15.9.1 FC_MR-4 Statistics Window

The Statistics window lists 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 Statistics window also has a Clear button. The Clear button sets the values on the card to zero. All counters on the card are cleared. Table 15-27 defines the FC_MR-4 card statistics parameters.

Table 15-27 FC_MR-4 Statistics Parameters

15.9.2 FC_MR-4 Utilization Window

The Utilization window shows the percentage of Tx and Rx line bandwidth used by the ports during consecutive time segments. 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 * 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 15-28.

Table 15-28 maxBaseRate for STS Circuits
STS	maxBaseRate
STS-24	850000000
STS-48	850000000 x 2^¹

¹For 1 Gbps of bit rate being transported, there are only 850 Mbps of actual data because of 8b->10b conversion. Similarly, for 2 Gbps of bit rate being transported, there are only 1700 Mbps (850 Mbps x 2) of actual data.

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

15.9.3 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 15-29. The listed parameters are defined in Table 15-27.

Table 15-29 FC_MR-4 History Statistics per Time Interval
Time Interval	Number of Intervals Displayed
1 minute	60 previous time intervals
15 minutes	32 previous time intervals
1 hour	24 previous time intervals
1 day (24 hours)	7 previous time intervals
