The ISR4300 family design, in order to forward traffic, is through an element referred as QuantumFlow Processor (QFP).Ĭaution: QFP is found on ASR1K as one or several physical chips, on the ISR4400 the same functionality is done with Cavium Octeon co-processors, on the ISR4300 that functionality is done on certain cores of the main Intel CPU. Note: The addition of all the processes can result into floating point values, IOSd rounds the result to the next integer. In order to display the processes that consume the most amount of CPU on the top, run the show process cpu sorted command: #show process cpu sortedĬPU utilization for five seconds: 1%/0% one minute: 0% five minutes: 0%Ħ4 103 10 10300 0.33% 0.02% 0.00% 0 Licensing Auto UĨ3 26 231 112 0.27% 0.00% 0.00% 0 PuntInject Keepa

CPU consumption of processes = 1% - 0% = 1% = All the processes CPU consumption listed on the command.

The difference between the total amount of CPU and the amount of CPU by interrupts are the values of CPU consumed by processes in order to corroborate add all the processes usage for the last five seconds: The output displays two values for the CPU usage, the first value is the total amount of CPU utilization and the second value is the amount of CPU by interrupts sent to IOSd:

In order to monitor the CPU usage on IOSd run the show process cpu command: #show process cpuĬPU utilization for five seconds: 1%/0% one minute: 1% five minutes: 0% IOS runs as a daemon, which is referred as IOS-Daemon (IOSd). ArchitectureĬisco ISR 4000 Series platforms run IOS-XE that has a distributed software architecture that runs a Linux kernel where IOS runs as one of many Linux processes. If your network is live, ensure that you understand the potential impact of any command.
