Other versions should also be supported following bellow’s procedure. IOL or IOS On Linux, also called IOU or IOS On Unix. IOL, is a simulator available for Cisco internal use only. IOL refers to the Linux version, compiled for i386 architecture. Origin product code generator free download. IOU refers to the Unix (Solaris) version compiled for Sparc architecture. The term IOU usually refers to IOL too. Because IOL is an internal IOS version, IOL can be used by Cisco employees or by authorized customers only. Upload the downloaded image to the EVE using for example FileZilla or WinSCP to: /opt/unetlab/addons/iol/bin/. Type following command to fix permissions: IOL images must end with the “.bin” extension and must be executable. License must be stored under the same path. IOU/IOL license is bound to the hostname and domain name of the server. A test should be made to check if IOU/IOL images can run properly. Google for how to create iourc license file. Bellow is an EXAMPLE how it should look like: If the IOL/IOU instance doesn’t start, then you won’t be able to use IOL/IOU nodes inside EVE. |
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

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:
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:
Clean and fix permissions:
mv c1710-bk9no3r2sy-mz.124-23.image /opt/unetlab/addons/dynamips/
Clean and fix permissions:
cd
rm -rf abc
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
4. CALCULATING IDLE PC
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:Free Cisco Ios Download
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.
