Understanding Processor Utilization in an ISR 4451-X
The ISR 4451-X introduces the concept of a split control and data plane to branch routing. Dividing the job of the router into multiple parts has some great advantages in areas such as performance reliability and throughput with services. However, with multiple CPUs in the system measuring processor utilization becomes more complex. This video explains the different processors in an ISR 4451-X system and how you can measure the utilization of each of them.
