Some Cisco IOS commands cause a spike in the CPU utilization Symptom: High CPU because of linux_iosd-imag. We did not see any CPU with show process cpu sorted but monitor platform so pro r0 shows linux_iosd-imag is showing close to 92% CPU High CPU on a Cisco router may be defined as the condition where the CPU utilization on the router is above the normal usage. In some scenarios the increased CPU usage is expected while in other scenarios it could indicate a problem A capacity issue is one of the symptoms of high CPU utilization on Cisco IOS routers. However, a capacity issue is almost never a symptom of high CPU utilization with hardware-based forwarding switches like the Catalyst 4500
From the output, it is clear that the Cisco IOS daemon consumes a major portion of the CPU along with the FED, which is the heart of this box. When CPU usage is high due to interrupts, you see that IOSd and FED use a major portion of the CPU, and these subprocesses (or a subset of these) use the CPU High CPU on a Cisco router may be defined as the condition where the CPU utilization on the router is above the normal usage.

After a number of attempts to resolve this issue failed and even.. Hardware-based forwarding switches and Cisco IOS® Software-based routers use the CPU in many different ways. The common misconception is that high CPU utilization indicates a depletion of resources on a device and an imminent crash

from our multilayer switch to GSR made CPU process high. // Net Input is a process that handles unknown types of Packets. These packets get sent directly to NULL, thus being black-holed. The CPU is spiking because your input queue is getting hit hard with whatever these packets are and is having to make a send to Null/discard decision If you suspect that one of these processes is causing the high CPU usage, you can use its ID to find it in the Task Manager and identify the faulty process. Open the Task Manager (press Control + Shift + ESC), IOSd: This is the Cisco IOS daemon that runs on the Linux kernel Cisco Confidential 26 • If the packet cannot be forwarded in the IOSd fast path, it gets punted in the usual IOS manner to an IOS process for process switching • Remember that most transit traffic is processed by QFP running its own code and IOSd doesn't see it • Although statistics is updated in IOSd via IPC messages, e.g.

Cisco IP Communicator has certain minimum requirements of the PC and operating system on which it runs. In the minimum configuration, Cisco IP Communicator consumes a substantial portion of the PC's CPU during calls. With additional CPU and RAM, the application will be more responsive and launch faster.

A keepalive time of 10 seconds with 5 retries seems to work well with HA because of the time it takes for the router to get into active mode

A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program.The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O. Symmetric multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes

Show more Show les Caution Because debugging output is assigned high priority in the CPU process, it can render the system unusable. For this reason, use the debug commands only to troubleshoot specific problems or during troubleshooting sessions with Cisco technical support staff. It is best to use the debug commands during periods of lower network traffic and fewer users show memory Command.
