Channel Monitor.. Channel diagnostics and network health monitoring.
Overview
This document describes the Functional Profile of a Channel Monitor object. It provides channel
diagnostics and network health monitoring information on the network. Further, the Channel
Monitor object can issue alarms if certain, configurable alarm limits are reached (e.g. the
number of packets with CRC is more than 10%).
Typically a Channel Monitor object is used on network infrastructure components. Specifically
it is designed to be incorporated into router designs, including designs with multiple routers in
one package. In this case there can be multiple Channel Monitoring objects, one for each channel the
routers can be attached to. The Channel Monitoring functional blocks themselves are part of a separate
monitoring node device, which is in the same package as the router(s). This is necessary since routers,
per definition, must not have any functional blocks. Typically there is one monitoring device per package.
Figure 1 shows a simple two-port router with a monitoring node in one package.
The Channel Monitor functional profile makes use of optional interfaces through the Node Object
functional block as described in this document.
Example Usage
The Channel Monitor network variables are normally polled by, or bound into, a monitoring or diagnostics device or application.
Examples include an embedded monitoring device, a controller in the network, or network tool that performing engineering, commissioning,
configuring, monitoring, control or diagnostics functions, whether it is attached permanently to the network or if it is temporarily
attached to the network by maintenance personnel
Figure 1
Additional ConsiderationsThe Channel Monitoring functional profile interacts with the Node Object in the following ways: If the Node Object network variable nviClearStat changes from OFF{0%,0} to ON{100%,1} all statistic counters of all Channel Monitoring functional blocks on this device are reset. This also includes the network variable nvoElapsedTime. The Node Object network variable nviClearStat is mandatory if at least one Channel Monitoring functional block is present on a device.

| nvoChnlAlarm | Channel alarm.: Indicates if the associated channel is in alarm state or shows a high error rate.
This output network variable signals indicates if the associated channel is in alarm state or shows a high error rate. A channel can be in alarm state due to one of the following conditions:
1. If maximum bandwidth utilization monitoring is implemented and is enabled via the CP nciBandUtlLimHighEnable, if nvoChnlAlarm was OFF{0%, 0} and the value for the last interval was greater than the CP nciBandUtlLimHigh, then nvoChnlAlarm will be set to ON{100%, 1}. If nvoChnlAlarm was ON{100%, 1} due to the above condition, the value drops below the CP nciBandUtlLimHigh minus the CP nciBandUtlHystHigh, and no other channel alarm condition is pending, then nvoChnlAlarm will be set to OFF{0%, 0}. The hysteresis value is used only to subtract from the limit value.
2. If minimum bandwidth utilization monitoring is implemented and is enabled with the CP nciBandUtlLimLowEnable, also set the CP nciBandUtlLimLow property to a non-zero value that is slightly below the expected level of an expected background heartbeat traffic. If the nvoChnlAlarm was OFF{0%, 0} and the value is now less than the CP nciBandUtlLimLow, then nvoChnlAlarm will be set to ON{100%, 1}. If nvoChnlAlarm was ON{100%, 1} due to the above condition, the value rises above the CP nciBandUtlLimLow plus the CP nciBandUtlHystLow, and no other channel alarm condition is pending, then nvoChnlAlarm will be set to OFF{0%, 0}. The hysteresis value is used only to add to the limit value.
3. If CRC error rate monitoring is implemented and is enabled via the CP nciCrcErrLimHighEnable, if the nvoChnlAlarm was OFF{0%, 0} and the value for the last interval was greater than the CP nciCrcErrLimHigh, thennvoChnlAlarm will be set to ON{100%, 1}. If nvoChnlAlarm was ON{100%, 1} due to the above condition, the value drops below the CP nciCrcErrLimHigh minus the CP nciCrcErrHystHigh, and no other channel alarm condition is pending, then nvoChnlAlarm will be set to OFF{0%, 0}. The hysteresis value is used only to subtract from the limit value.
4. If missed packet rate monitoring is implemented and is enabled via the CP nciMissedLimHighEnable, if the nvoChnlAlarm was OFF{0%, 0} and the value for the last interval was greater than the CP nciMissedLimHigh, thennvoChnlAlarm will be set to ON{100%, 1} .If nvoChnlAlarm was ON{100%, 1} due to the above condition, the value drops below the CP nciMissedLimHigh minus the CP nciMissedHystHigh, and no other channel alarm condition is pending, then nvoChnlAlarm will be set to OFF{0%, 0}. The hysteresis value is used only to subtract from the limit value.
5. If missed preamble rate monitoring is implemented and is enabled via the CP nciMisPreLimHighEnable, if the nvoChnlAlarm was OFF{0%, 0} and the value for the last interval was greater than the CP nciMisPreLimHigh, thennvoChnlAlarm will be set to ON{100%, 1}. If nvoChnlAlarm was ON{100%, 1} due to the above condition, the value drops below the CP nciMisPreLimHigh minus the CP nciMisPreHystHigh, and no other channel alarm condition is pending, then nvoChnlAlarm will be set to OFF{0%, 0}. The hysteresis value is used only to subtract from the limit value.
Valid Range
Only the value pairs ON{100%, 1} and OFF{0%, 0} are used.
Default Value
OFF{0%, 0}
Configuration Considerations
The configuration properties nciBandUtilLimHigh, nciBandUtilLimLow nciCrcErrLimHigh, nciMissedLimHigh, and nciMissPreLimHigh define the limits used to determine the channel alarm condition, while the configuration properties nciBandUtilLimHighEnable, nciBandUtilLimLowEnable nciCrcErrLimHighEnable, nciMissedLimHighEnable, and nciMissPreLimHighEnable are used to enable these checks and configuration properties nciBandUtilHystHigh, nciBandUtilHystLow nciCrcErrHystHigh, nciMissedHystHigh, and nciMissPreHystHigh are used for hysteresis. The condition is always checked at the end of each monitoring interval as defined by the configuration property nciMonInterval.
When Transmitted
The output variable is transmitted:
Upon node reset, after obtaining valid data.
When the statistics were reset.
Whenever it changes its value. A new value is calculated at the end of each monitoring interval as defined by the configuration property nciMonInterval.

| cpBandUtlLimLow | Bandwidth utilization low limit.:
The low alarm limit can be useful to detect that, for instance, a certain level of background heartbeat traffic expected on a channel has slowed or stopped-which indicates a power, channel wiring, or other problem. If the low alarm limit is enabled with nciBandUtlLimLowEnable, also set the nciBandUtlLimLow property to a non-zero value that is slightly below the expected level of background heartbeat traffic. If the alarm type was not AL_LOW_LMT_ALM_1 and the value is now less than nciBandUtlLimLow, then the alarm type becomes AL_LOW_LMT_ALM_1 and nvoChnlAlarm will be set to True.If the alarm type was AL_LOW_LMT_ALM_1 and the value rises above nciBandUtlLimLow plus nciBandUtlHystLow, then the alarm type becomes AL_LOW_LMT_CLR_1 and nvoChnlAlarm will be set to False. The hysteresis value is used only to add to the limit value.
