Configuring and Displaying Queue-Level PMs (CLI)
PTP 820 devices support advanced traffic PMs per CoS queue and service bundle. For each logical interface, you
can configure thresholds for Green and Yellow traffic per queue. You can then display the following PMs for 15-
minute and 24-hour intervals, per queue and color:
•
Maximum bytes passed per second
•
Minimum bytes passed per second
•
Average bytes passed per second
•
Maximum bytes dropped per second
•
Minimum bytes dropped per second
•
Average bytes dropped per second
•
Maximum packets passed per second
•
Minimum packets passed per second
•
Average packets passed per second
•
Maximum packets dropped per second
•
Minimum packets dropped per second
•
Average packets dropped per second
•
Seconds bytes per second were over the configured threshold per interval
These PMs are available for any type of logical interface, including groups. To activate collection of these PMs, the
user must add a PM collection rule on a logical interface and service bundle and set the relevant thresholds per
CoS and Color. When the PM is configured on a group, queue traffic PMs are recorded for the group and not for
the individual interfaces that belong to the group.
One collection rule is available per interface.
PMs for queue traffic are saved for 30 days, after which they are removed from the database. It is important to
note that they are not persistent, which means they are not saved in the event of unit reset.
