 Limit CPU Utilization in GNS3 for running IOS

You can use IdlePC for limiting the CPU usage while running IOS routers. In addition to IdlePC, you can try the below steps to further limit the CPU usage.

Click in the Dynagen management console at the bottom of the page. Enter the command:
idlepc idlemax /all 100

Check your CPU utilisation now. It will probably have dropped. If it hasn't dropped enough, you can try another value. eg:
idlepc idlemax /all 10



Limit CPU utilization in GNS3 for running ASA
There are no idle-pc values available for PIX firewalls at this time. Instead, you may use third-party software to control your CPU usage. There are a variety of products on the market. The one that I use for Windows is called BES and is a free download.
You can set the control value to -60%, at which ASA works fine without much lagging on Intel Core i5 machine. Of-course you can tune it more than that like -70% or -75% to further reduce the CPU utilization.

Terminal command for using SecureCRT

"C:\Program Files\VanDyke Software\SecureCRT\SecureCRT.exe" /SCRIPT securecrt.vbs /ARG %d /T /TELNET 127.0.0.1 %p

Ansible-Playbook to display output of multiple show commands (using stdout_lines with Loop)

 In this playbook, we we'll see how we can get display of multiple show commands in stdout_lines format. We can make use of loops (or with_items) for submitting multiple commands, but debug output with stdout_lines does not gives the formatted result as it would give for single command. So in case of multiple commands, we can debug the output of each command separately in stdout_lines format.

Filtering Routes in BGP using Route-maps and Prefix-list

Image
Order of preference of attributes in BGP The order of preference varies based on whether the attributes are applied for inbound updates or outbound updates. For inbound updates the order of preference is:     route-map     filter-list     prefix-list, distribute-list For outbound updates the order of preference is:     prefix-list, distribute-list     filter-list     route-map NOTE: The attributes prefix-list and distribute-list are mutually exclusive, and only one command (neighbor distribute-list or neighbor prefix-list) can be applied to each inbound or outbound direction for a particular neighbor. Scenario: We own the AS500 and advertising a network block of 192.0.2.0/24 and 180.179.179.0/16 to two different ISPs. Objectives: Configure router R1 to establish eBGP neighbor relationship with ISP1. Configure router R1 to establish eBGP neighbor relationship with ISP2. Advertise  192.0.2.0/24 ...

Ansible Playbook for Network OS Upgrade with pre and post checks

You have 100s of network switches or routers that you need to upgrade. How much time would it take for you to do the upgrades? There are a lot number of sub-tasks involved while upgrading IOS image of a Cisco router or a switch.

Bypassing Proxy Server in Google Chrome

There may be times when you might want to use Google Chrome and do not wish to use the proxy settings for which you are bound to use in Internet Explorer because of your company policies.
