delay-profile interfaces subcommands

The following commands are to edit the delay-profile parameters.

According to IGP-TE RFC8570 and RFC7471, the advertised delay should be unidirectional. So when the mode is set to two-way, the advertised delay is “Average_RTT_delay / 2” and when the mode is set to one-way, the advertised delay is “Average_FWD_delay”. The default value is “two-way”.

Parameters

one-way

The one-way value sets the mode to one-way measurement.

two-way

The two-way value sets the mode to two-way measurement.

<1000-15000>

Set the burst interval in milliseconds. The default value is 3000 milliseconds and the range is 1000-15000 milliseconds.

<1-10>

Set the number of packets to be sent at each burst interval. The default value is 3.

The limit <1-10> is applicable only on Qumran2 (Q2) series platforms. For Qumran1 (Q1) series platforms it is llimited to <1-5>.

<30-3600>

Set the computation interval in seconds. The default computation interval is 30 seconds. The range is 30-3600 seconds. This will be used also as the periodic advertisement interval.

<1-100>

Set the advertisement threshold percentage in the range of 1-100 (for periodic, default=10% and for accelerated, default=20%.

<1025-65535>

Set the TWAMP sender port value in the range 1025-65535. If not specified, the default value is 862).

<0-10000>

Set the advertisement minimum change in microseconds in the range 0-10000 (for periodic, default=1000 and for accelerated, default=2000).

notification threshold <1-100>

Set the threshold percentage in the range of 1-100 that NETCONF Notifications and SNMP Traps should be triggered (default value is 10%).

notification minimum-change <0-10000>

Set the minimum change in microseconds in the range 0-10000 that NETCONF Notifications and SNMP Traps should be triggered (default=1000).

Command Mode

Delay profile interface mode

Default

Two-way

Applicability

Introduced in OcNOS version 5.1. The burst count limit has been increased from on <1-5> to <1-10> on Qumran2 (Q2) series platformsin OcNOS version 7.0.0.
