distribution
Statistics distributions are defined by number and range of bins per interval.
A bin is a counter that counts the number of measurements initiated and completed during a specified
length of time for each operation. The results of performance measurements falling within a specified
range are stored in each bin. When the number of distributions reaches the number and range specified,
no further distribution-based information is stored.
The lower bound value for the first upper boundary is always 0 microseconds, such as 0 to 5000
microseconds for the default first upper boundary.
The maximum allowed value for the uppermost boundary is -1 microsecond.
An aggregate interval is the length of time during which the performance measurements are conducted
and the results stored. You can configure the interval by using the aggregate interval command.
To avoid significant impact on router memory, careful consideration should be used when configuring
distribution.
Examples The following example shows how to configure the sender MEP to calculate two-way, delay-variation
performance measurements for a single-ended IP SLAs Metro-Ethernet 3.0 (ITU-T Y.1731) operation,
and store the statistics in five bins:
Switch(config-term)# diagnostic start test 1
Switch(config-term)# ip sla 10
Switch(config-ip-sla)# ethernet y1731 delay dmm domain xxx evc yyy mpid 101 cos 3 source
mpid 100
Switch(config-sla-y1731-delay)# distribution delay-variation two-way 5
5000,10000,15000,20000-1
Switch(config-sla-y1731-delay)#This example shows how to start diagnostic test 3. Running
this test disrupts the normal system operation and then reloads the switch.
