window-integrity number


	Synopsis	Sample percentage required for window integrity report
	Context	configure test-oam link-measurement measurement-template string aggregate-sample-window window-integrity number
	Tree	window-integrity
	Description	This command configures the percentage value that is used to determine whether the aggregate sample window is integral, by comparing the number of samples received from the sample window to the percentage configured. The configured percentage translates to a required sample window count that must be included in the aggregate sample window. The number of samples is computed as follows: (window-integrity (%)) x (((aggregate-sample-window length (s)) / (sample-window length (s))) If the number of samples in the aggregate sample window is equal to or greater than the computed number of required samples, the sample window has integrity and the aggregate sample window result is compared to the configured sample window thresholds. If the count is less than the computed number of required samples, the aggregate sample window does not have integrity and the value is not considered as representative. In this case the aggregate sample window results are not compared to the configured sample window thresholds. If this parameter is not configured, integrity checking is disabled and all results are compared to the configured thresholds.

	Synopsis	Time to wait to flush the last reported delay
	Context	configure test-oam link-measurement measurement-template string last-reported-delay-hold number
	Tree	last-reported-delay-hold
	Description	This command configures the timer that specifies the wait time before the last reported delay measurement is flushed after a link measurement test enters the operationally down state. The aging timer delays the flushing of the last reported delay metric to the routing engine. This timer starts a countdown to zero when an administrative function causes the operational state of the test on that specific interface to transition from up to down. If the timer expires before the operational state transitions to up, the previously reported value is flushed. The Delay Measurement Last Reported indicates “Cleared”. The timestamp indicates the time of the clear event. The Triggered By indicates “Expired”. If the administrative state recovers to operationally up before the expiration of the timer, the previous reported value is not flushed. The aging timer does not apply to failure conditions that do not affect the administrative state of the interface, for example interface failure or routing changes.

	Tree	window-integrity
	Description	This command configures the percentage value that is used to determine whether the sample window has enough samples to be considered representative for that window (integrity), by comparing the number of samples received from the sample window to the percentage configured. The configured percentage considers the interval of probes and the length of the sample window to determine the number of packets required in the sample: (window-integrity (%)) x ((sample-window length (s)) / pps per test (interval)) If the count is less than the computed number of required samples, the sample window does not have integrity and the sample window results are not compared to configured sample window thresholds. If the count is equal to or greater than the computed number of required samples, the sample window has integrity and the aggregate sample window result is compared to the configured sample window thresholds. If the count is less than the computed number of required samples, the sample window does not have integrity and the value is not considered as representative. In this case the sample window results are not compared to the configured sample window thresholds. If this parameter is not configured, integrity checking is disabled and all results are compared to the configured thresholds.

Use the configure test-oam twamp twamp-light source-udp-port-pools port pool-type command to map the port range to the application. By default a source UDP port allocates from the dynamic range. The configuration of the source port should only be configured when required for interoperability. When the source IP, destination IP, and destination UPD port are the same for a test, the source UDP port must be different in order to uniquely identify the session.

	Synopsis	Frame loss ratio for a policing test
	Context	configure test-oam service-activation-testhead acceptance-criteria-template string loss-threshold-policing decimal-number
	Tree	loss-threshold-policing
	Description	This command configures a frame loss ratio (FLR) value for a policing test. The value is compared to the measured FLR at the end of the test to determine the test result. If the measured value is greater than the configured value, the test fails; otherwise, it passes. Thresholds must be explicitly configured before they can be used for comparison. The FLR is computed as a ratio of the difference of the number of received frames to the number of injected or sent frames divided by the number of sent frames.

	Description	This command configures the margin by which the observed throughput is off from the configured throughput to determine whether a service test passes or fails. The M-factor is used with the CIR threshold and PIR threshold values for different test types to determine whether a test passes or fails. type cir If the measured throughput is less than the difference of the configured CIR threshold and the M-factor, the test fails. type cir-pir If the measured throughput is less than the difference of the configured PIR threshold and the M-factor, the test fails. type policing If the measured throughput is less than the difference of the configured PIR threshold and the M-factor, the test fails. If the measured throughput is greater than the sum of the configured PIR threshold and the M-factor, the test fails. type performance If the measured throughput is less than the difference of the configured PIR threshold and the M-factor, the test fails.

	Description	When configured to true, this command configures the acceptance of IPv6 packets with UDP checksums of 0. This optional configuration allows the router to process arriving IPv6 TWAMP Test packets that contain IPv6 UDP checksum of 0x0000. The UDP port specific to this TWAMP Light test bypasses the default discard IPv6 UDP checksum 0x0000. If this optional command is not configured, IPv6 UDP checksum 0x000 arriving packets are discarded. When configured to false, packets that arrive with an IPv6 UDP checksum of 0x0000 are discarded.

	Description	This command maps the specified source UDP port to the TWAMP Light application allowed to configure the source UDP port. OAM-PM IP tests can only configure the source UDP port when the port pool UDP source port is configured with a pool-type oam-pm. The test-oam link-measurement measurement-template can only configure the src-udp-port when the port pool UDP source port is configured with pool-type link-measurement. A pool type cannot be changed if its current application is a test (either an oam-pm session or link-measurement template) and is configured to use the specified port, regardless of the administrative or operational state. The configuration reference linking to the source UDP prevents the change.
