Description

Configure the threshold value for average frame delay variation, in microseconds, for two-way Ethernet frame delay measurement (ETH-DM). When the configured threshold for average frame delay variation is exceeded, an SNMP trap is generated for ETH-DM. SNMP traps are triggered if you configure either the average frame-delay threshold or the average inter-frame delay variance threshold. If you do not configure either the frame-delay threshold or the frame delay variation threshold, no SNMP traps are generated. You can configure these threshold values only with a two-way ETH-DM SLA iterator.

Frame delay refers to the difference, in microseconds, between the time a frame is sent and when it is received. Frame delay variation refers to the difference, in microseconds, between consecutive frame delay values. Frame delay variation is sometimes called “frame jitter.” For one-way Ethernet frame delay measurement, only the receiver MEP (on the remote system) collects statistics. For two-way Ethernet frame delay measurement, only the initiator MEP (on the local system) collects statistics. In two-way ETH-DM mode, frame delay and frame delay variation values are based on the time difference between when the initiator MEP transmits a request frame and receives a reply frame from the responder MEP, subtracting the time elapsed at the responder MEP.

Options

avg-ifdv-twoway-threshold-value—Threshold value for average frame delay variation, in microseconds, for two-way ETH-DM.

  • Range: 1 through 4294967295 microseconds

flap-trap-monitor seconds—Duration in seconds, for summarizing flap occurrences and send out a single jnxSoamPm ThresholdFlapAlarm notification to the network management system (NMS).

  • Range: 1 through 360 seconds

Required Privilege Level

configure—To enter configuration mode.

control—To modify any configuration.
