PEMU 10 Steps for Dummies

by CiscoSpot

Any distribution is welcome, please feel free to contact net@netap.com

1. Download PEMU and decompress it to any folder.

2. Copy PIX OS to the same folder with PEMU.

3. Change the image in pemu.ini file, take pix802.bin for example.

4. Create one .bat file and edit it with the following contents. It’s in ONE line.

Pemu -net nic,vlan=1,macaddr=00:00:0c:00:00:01 -net udp,vlan=1,sport=8000,dport=9000,daddr=127.0.0.1 -net nic,vlan=2,macaddr=00:00:0c:00:00:02 -net udp,vlan=2,sport=8001,dport=9001,daddr=127.0.0.1 -net nic,vlan=3,macaddr=00:00:0c:00:00:03 -net udp,vlan=3,sport=8002,dport=9002,daddr=127.0.0.1 -serial telnet::4444,server -m 128 FLASH

5. Make a copy of FLASH.empty and change the name to FLASH.

6. Run the .bat file that created.

7. Telnet to 127.0.0.1 4444. If any problem occurred when decompressing the image, you have one option that you change the pix.bin to pix.rar and decompress then get the file pix. Copy it to the PEMU folder and change the pemu.ini to map to this image, “image=pix”.

8. The CPU utilization will be 100%, and there is no tool integrated in PEMU. Download BES and run it to control the CPU utilization.

Dynamips has changed the network world and it helped many network fans to obtain the network labs without paying any fee. It is fantastic when you are running several Cisco Routers on your computer, even an entire CCIE Lab!

I do believe there are some guides in the internet which you can follow to use the Dynamips, however, a few my friends are interested on this and I am too lazy to explain It is a draft instead of a real guide, just call it

The website you must know if you are going to be a Dynamiper.

Dynamips Official Blog, http://www.ipflow.utc.fr/blog/
Dynagen Official website, http://dynagen.org/
Winpcap Official website, http://www.winpcap.org/

Step by Step

1. Download Winpcap, http://www.winpcap.org/install/default.htm

2. Download Dynagen,
http://sourceforge.net/project/showfiles.php?group_id=160317

3. Install Winpcap.

4. Install Dynagen.

Three shortcuts will appear on your desktop, Dynagen Sample labs (Folder), Dynamips Server, Network device list. Double-click Dynagen Sample labs and you will see a file called “all_config_options.txt”, which is quite useful for you. Open it by Wordpad instead of Notepad and view the options you can utilize in the labs.

Open “Simple lab 1” and right-click the simple1.net then choose “Edit network file”, and choose Wordpad to open it. It is a 7200 platform and there are two routers in the diagram using 160MB ram, respectively. The main configurations inside are as below.

5. Download Cisco IOS for Cisco 3600 serials.
Although Dynamics support several Cisco platforms, personally I prefer 3640 when comparing the RAM requirement, modules support and IOS features. You can search IOS resources from internet yourself.
