Monitoring Cisco SCE Platform Utilization
Revised: February 07, 2014, OL-30621-02
Introduction
This appendix explains how to monitor Cisco SCE platforms that are installed in real traffic.

“Cisco SCE Platform Utilization Indicators” section on page B-2

As with any network device, the Cisco SCE platform has its performance and capacity envelopes. As the
network evolves, the utilization of the Cisco SCE platform can increase and these envelopes might be
reached. It is, therefore, advisable to monitor Cisco SCE platform to be sure that utilization remains at
a level that supports reliable and consistent service.
When the Cisco SCE platform reaches its performance envelopes, it activates certain mechanisms that
insure that no traffic will be dropped while in this state. These mechanisms will prioritize packet
handling over service related actions. As a result, symptoms of service loss might be experienced.
Following are several examples:
•
Broken reports during the congestion period (sometimes appears as saw-tooth pattern).
•
Bandwidth enforcement levels are not met.
•
No UDP traffic is being reported (this is because the Cisco SCE platform will automatically filter
all UDP traffic in certain cases as a last resort).
Monitoring the Cisco SCE platform can be divided onto two main areas:
•
Monitoring Cisco SCE platform utilization
•
Monitoring service loss
