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. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.
