jnxPingCtlTable

The enterprise-specific Ping MIB structure includes one main object, jnxPingCtlTable, whose object identifier is jnxPingObjects 2, and defines the jnxPing control table for providing enterprise-specific options to the corresponding pingCtlEntry. jnxpingCtTable monitors thresholds; for example, the maximum allowed jitter in the trip time during a text.

For information about objects in jnxPingCtlEntry, see:

jnxPingCtlEntry

Each jnxPingCtlEntry has two indexes identical to those of the corresponding pingCtlEntry. Entries created in pingCtlTable are mirrored here. jnxPingCtlEntry objects are listed in the Table 1.

Table 1: jnxPingCtlEntry

Object

Object Identifier

Description

jnxCtlOwnerIndex

jnxPingCtlEntry 1

The first index. It is identical to the pingCtlOwnerIndex of the corresponding pingCtlEntry in the pingCtlTable.

jnxPingCtlTestName

jnxPingCtlEntry 2

The other index and is identical to the pingCtlTestName of the corresponding pingCtlEntry in the pingCtlTable.

jnxPingCtlIfName

jnxPingCtlEntry 3

Specifies the name of the outgoing interface for ping probes. This is the name-based complement to pingCtlIfIndex. A zero-length string value for this object means that this option is not enabled. The following values can be set simultaneously, but only one value is used. The precedence order is as follows:

  • pingCtlIfIndex (see pingCtlTable in the Ping MIB)
  • jnxPingCtlIfName
  • jnxPingCtlRoutingInstanceName

jnxPingCtlRoutingInstanceName

jnxPingCtlEntry 6

Specifies the name of the routing instance used when directing outgoing ping packets. The instance name specified must be configured at the [edit routing-instances] hierarchy level of the JUNOS configuration. The instance-type must be vrf.

jnxPingCtlRttThreshold

jnxPingCtlEntry 7

The maximum round-trip time allowed. If this threshold is crossed by any probe, a jnxPingRttThresholdExceeded trap is sent.

jnxPingCtlRttStdDevThreshold

jnxPingCtlEntry 8

The maximum round-trip time standard deviation allowed over the course of any test. If the calculated standard deviation of the round-trip time at the end of any test exceeds this threshold, a jnxPingRttStdDevThresholdExceeded trap is sent.

jnxPingCtlRttJitterThreshold

jnxPingCtlEntry 9

The maximum allowed jitter in the round-trip time over the course of any test. Jitter is the difference between the maximum and minimum round-trip times measured over the course of a single test (jnxPingResultsMaxRttUs minus jnxPingResultsMinRttUs). If the measured jitter exceeds this threshold, a jnxPingRttJitterThresholdExceeded trap is sent.

jnxPingCtlEgressTimeThreshold

jnxPingCtlEntry 10

Maximum egress trip time allowed. If this threshold is crossed by any probe, a jnxPingEgressThresholdExceeded trap is sent. This applies only if the probe type (pingCtlType) provides one-way delay measurements. Currently jnxPingIcmpTimeStamp is the only supported probe type with this property.

jnxPingCtlEgressStdDevThreshold

jnxPingCtlEntry 11

The maximum egress trip time standard deviation allowed over the course of any test. If the calculated standard deviation of the egress trip time at the end of any test exceeds this threshold, a jnxPingEgressStdDevThresholdExceeded trap is sent. This applies only if the probe type (pingCtlType) provides one-way delay measurements. The jnxPingIcmpTimeStamp is the only supported probe type with this property.

jnxPingCtlEgressJitterThreshold

jnxPingCtlEntry 12

The maximum allowed jitter in the egress trip time over the course of any test. Jitter is defined as the difference between the maximum and minimum egress trip times measured over the course of a single test (jnxPingResultsMaxSrcDstt minus jnxPingResultsMinSrcDstt). If the measured jitter exceeds this threshold, a jnxPingEgressJitterThresholdExceeded trap is sent. This applies only if the probe type (pingCtlType) provides one-way delay measurements. The jnxPingIcmpTimeStamp is the only supported probe type with this property.

jnxPingCtlIngressTimeThreshold

jnxPingCtlEntry 13

The maximum ingress trip-time allowed. If this threshold is crossed by any probe, a jnxPingIngressThresholdExceeded trap is sent. This applies only if the probe type (pingCtlType) provides one-way delay measurements. The jnxPingIcmpTimeStamp is the only supported probe type with this property.

jnxPingCtlIngressStddevThreshold

jnxPingCtlEntry 14

The maximum ingress trip time standard deviation allowed over the course of any test. If the calculated standard deviation of the ingress trip time at the end of any test exceeds this threshold, a jnxPingIngressStddevThresholdExceeded trap is sent. This applies only if the probe type (pingCtlType) provides one-way delay measurements. Currently, jnxPingIcmpTimeStamp is the only supported probe type with this property.

jnxPingCtlIngressJitterThreshold

jnxPingCtlEntry 15

The maximum allowed jitter in the ingress trip time over the course of any test. Jitter is defined as the difference between the maximum and minimum ingress trip times measured over the course of a single test (jnxPingResultsMaxDstSrct minus jnxPingResultsMinDstSrct). If the measured jitter exceeds this threshold, a jnxPingIngressJitterThresholdExceeded trap is sent. This applies only if the probe type (pingCtlType) provides one-way delay measurements. The jnxPingIcmpTimeStamp is the only supported probe type with this property.

jnxPingCtlTrapGeneration

jnxPingCtlEntry 16

The value of this object determines when and if to generate a notification for this entry.

rttThreshold(0)—Generate a jnxPingRttThresholdExceeded notification when the configured RTT threshold is exceeded.

rttStdDevThreshold(1)—Generate a jnxPingRttStdDevThresholdExceeded notification when the configured RTT standard deviation threshold is exceeded.

rttJitterThreshold(2)—Generate a jnxPingRttJitterThresholdExceeded notification when the configured RTT jitter threshold is exceeded.

egressThreshold(3)—Generate a jnxPingEgressThresholdExceeded notification when the configured egress threshold is exceeded. This applies only if the probe type supports one-way measurements.

  

egressStdDevThreshold(4)—Generate a jnxPingEgressStdDevThresholdExceeded notification when the configured egress standard deviation threshold is exceeded. This applies only if the probe type supports one-way measurements.

egressJitterThreshold(5)—Generate a jnxPingEgressJitterThresholdExceeded notification when the configured egress jitter threshold is exceeded. This applies only if the probe type supports one-way measurements.

ingressThreshold(6)—Generate a jnxPingIngressThresholdExceeded notification when the configured ingress threshold is exceeded. This applies only if the probe type supports one-way measurements.

ingressStdDevThreshold(7)—Generate a jnxPingIngressStdDevThresholdExceeded notification when the configured ingress standard deviation threshold is exceeded. This applies only if the probe type supports one way measurements.

ingressJitterThreshold(8)—Generate a jnxPingIngressJitterThresholdExceeded notification when the configured ingress jitter threshold is exceeded. This applies only if the probe type supports one-way measurements. The value of this object defaults to zero, indicating that none of the above options have been selected.
