I want to list all processes and it's cpu usage, Can the "tasklist" command acheive? I want to list Image Name,PID,and CPUUsage througn cmd command like this, but it has no cpu usage. From the system processes extensive output, the following processes may show high CPU utilization depending on how one is accessing the device. In this post I will demonstrate a few useful show commands that will help me see the state of the routers DHCP server which I set up in the previous post. Cisco Commands (6) Concept. SSH from cisco router and switch to another. After reviewing the configuration using the 'show running-config' command, we checked each of our bonded networking interfaces with 'the show interface' command to see if we could uncover any errors, dropped packets, etc. This chapter explains how to use the VPN Client command-line interface (CLI) to connect to a Cisco VPN device, generate statistical reports, and disconnect from the device. This is excellent for managing your system processes, resources and ensure everything is working fine and your server isn't bogged down. ProCurve has a complete command line interface mode with these commands and in this brief post, I will give you a glance of what everything can be found there. Symptom: Catalyst 3650/3850 switches (stack or standalone) may report following symptoms: - CPU usage of Core 0 is in the range of 90 - 100% - "fed" and its subprocess "fed-ots-main" are high even with not much traffic sent to the cpu - Check the cpu queues by command "show platform punt statistics port-asic 0 cpuq -1 direction rx", forus queue (RXQ 2: CPU_Q_FORUS_TRAFFIC) increase repidly (E. com, and Cisco DevNet. show cdp neighbor will show attached devices, not ports. 1 IP address.
