Dynamips is a Cisco router emulator. Supported platforms are 1700, 2600, 3600, 3700 and 7200 routers. Each IOS has an associated Idle PC value. Idle PC is used to map the idle instruction of the running IOS to the idle instruction of the UNetLab platform. With a good Idle PC value, the CPU usage should be less than 10% for each instance.

Eve-ng is a platform where you can add Cisco routers images and can do unlimited practice for your certification. In Eve-ng you can practice lab up to CCIE level

We will tell you step by step process of How to add Cisco IOS images to EVE-ng

1. Supported Dyanamips Images
2. Download Cisco IOS (Dyanamips Images)
3. Importing Cisco IOS image to Eve-ng
4. Calculating Idle-PC

if you want to practice Cisco ASA / IOU/ IOL on eve-ng for your certification or knowledge then check below posts-

You can download Cisco IOS (dynamips images) from below links.

3. Add Cisco IOS (Dynamips images) to Eve-ng

If you are uploading the zip file then install the required package-

Install required packages:
apt-get -y install unzip

Upload the downloaded image to the Eve-ng master node using for example FileZilla or WinSCP. Then login as root using SSH protocol and uncompress it:

Cisco Ios Router Images Download

Create tmp directory
mkdir abc

Using EVE CLI, uncompress original image. Output file extension must be .image. Be sure you are using properly your source and output filenames.

cd abc
unzip -p c1710-bk9no3r2sy-mz.124-23.bin > c1710-bk9no3r2sy-mz.124-23.image

Move uncompressed image to destination folder:
mv c1710-bk9no3r2sy-mz.124-23.image /opt/unetlab/addons/dynamips/

Clean and fix permissions:
rm -rf abc
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions


If an unsupported image is added to the UNetLab platform, an Idle PC value must be identified. Start a Dynamips instance with basic configuration:

CPU usage is very high, a whole CPU for each instance:

Wait for the following line on the console:

Exit from initial configuration dialog, and quit to get the con0 prompt:

After few more seconds press CTRL + ] then i. Dynamips will show suggested Idle PC values:

Select one and restart dynamips with the IDle PC value:

If CPU usage is lower, then a good Idle PC value has been found:

Usually the highest value of IDLE PC will best for your CPU. In the calculation above it is 76. Copy value of IDLE PC to the notepad and we can start test best value fit for your Dynamips node.

To stop dynamips router calculation mode use:

Key combo CTRL and ] then q

Go to EVE WEB GUI, add your Dynamips node and change IDLE PC value to calculated, save and start node.

Check your CPU with top command (cpu check section above)

If CPU usage is lower, then a good IDLE PC value has been found:

If CPU is still high, then another value must be tested.
