Introduction
I started in August 2005 a project to emulate a Cisco 7200 on a traditionnal PC. Now, it also supports Cisco 3600 series (3620, 3640 and 3660).
The goals of this emulator are mainly:
To be used as a training platform, with software used in real world. It would allow people to become more familiar with Cisco devices, Cisco being the world leader in networking technologies ;
Test and experiment the numerous and powerful features of Cisco IOS ;
Check quickly configurations to be deployed later on real routers.
Of course, this emulator cannot replace a real router: you should be able to get a performance of about 1 kpps (depending on your host machine), to be compared to the 100 kpps delivered by a NPE-100 (the oldest NPE model). So, it is simply a complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA/CCNP/CCIE exams.
Current status
At this time, the emulator I have programmed is able to boot a large number of Cisco IOS releases available for the 7200 and 3600 platforms, including the latest 12.2S and 12.4T.
The following devices are emulated in the current release (0.2.5):
MIPS64 CPU processor. The instruction set is not completely emulated now (FPU support is lacking, TLB support is not finished and other minor things), but it is sufficient for IOS ;
DRAM and Packet SRAM memory ;
Non-Volatile Memory (NVRAM) ;
Signetics SCN 2681 DUART (C7200 Console and AUX ports) ;
National Semiconductors NS16552 DUART (C3600 Console and AUX ports) ;
Dallas DS1620 Temperature Sensors and Voltage Sensors, allowing the C7200 Environmental Monitor to work properly ;
NMC93C46 Serial EEPROM ;
Bootflash of 8 Mb (Intel 28F016SA) ;
Galileo GT64010/GT64120 PCI controller, DEC 21x50 PCI bridges and so ;
PCMCIA ATA disk emulation (C7200 only at this time).
The following Cisco 7200 Port Adapters (PA) are currently supported:
FastEthernet cards "C7200-IO-FE" and "PA-FE-TX" based on DEC21140 chip
Ethernet cards "PA-4E" and "PA-8E" based on AMD Am79c97x chips
ATM card "PA-A1" based on Texas Instruments Tneta1570 chip
Serial cards "PA-4T+" and "PA-8T"
POS (Packet over Sonet) card "PA-POS-OC3" (experimental, only works with recent IOS images)
The following Cisco 3600 Network Modules (NM) are currently supported:
Ethernet cards: "NM-1E", "NM-4E" and "NM-1FE-TX", all based on AMD Am79c97x chips
Serial card "NM-4T"
You can also get development info and beta versions on my technical blog (http://www.ipflow.utc.fr/blog).
To run at a decent speed, the emulator uses a JIT (Just In Time) compiler, which is working on x86 CPU (like Pentium) and x86_64 CPU (AMD64/Intel EM64T). It is also possible to run the emulator without the JIT support on non-x86 machines, but it is slower.
You can find some information about the C7200 hardware on the Cisco Web site (http://www.cisco.com/en/US/products/hw/routers/ps341/products_tech_note09186a00800942e0.shtml)
Lab simulation / "Hypervisor" mode
With the introduction of the 0.2.5 release, it is now possible to run the emulator as an "hypervisor" to start and control many virtual router instances simultaneously.
Dynagen (http://dyna-gen.sourceforge.net/), by Greg Anuzelli, is a front-end (written in Python) that makes lab simulation with the hypervisor very easy: it uses an INI-like configuration file to provision Dynamips emulator networks. It takes care of specifying the right port adapters, generating and matching up those pesky NIO descriptors, specifying bridges, frame-relay, ATM switches, etc. It also provides a management CLI for listing devices, suspending and reloading instances, etc. You can also distribute virtual instances across different servers to set up complex labs. To begin with Dynagen, you can consult this very complete tutorial (http://dyna-gen.sourceforge.net/tutorial.htm).
Dynagui (http://dynagui.sourceforge.net/) is a graphical front-end written by Yannick Le Teigner. It uses Dynagen to communicate with the hypervisor.
Contributors are welcome ! :)
For people interested to contribute there is a TODO List.
There are many things to do: PowerPC emulation, a more efficient JIT, network device emulation, new platforms...
Download
The current release is 0.2.5, published Sep 14, 2006 (you can consult the README file (http://www.ipflow.utc.fr/dynamips/README-0.2.5.txt)).
You have to download only one binary file corresponding to your architecture:
Executable for Linux/x86 (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.5-x86.bin)
Executable for Linux/x86_64 (AMD64 and EM64T) (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.5-amd64.bin)
Executable for Windows (with Cygwin DLL) (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.5-cygwin.zip)
If you are using the Windows version, you have to download and install the WinPcap library (http://www.winpcap.org/). The minimum required version is 0.4beta1. Thanks to WinPCAP, it is possible to access the Ethernet card of host machine to send/receive packets on the LAN.
You can also download the source code, published under the GNU General Public Licence (GPL):
The source code of release v0.2.5 (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.5.tar.gz)
Remark: the sources include 3 files which are not written by me: amd64-codegen.h and x86-codegen.h from the Mono project (http://www.mono-project.com), and base64.c from Fetchmail, all under GPL licence. Of course these files keep their licences and their copyrights.
How to use it ?
Very important remark: by default, an instance will take 100% of the host CPU. To avoid this, please read the "idle-pc" section in the README file (http://www.ipflow.utc.fr/dynamips/README-0.2.5.txt).
To boot quickly, the preferred method is to decompress the IOS image with the "unzip" utility. It avoids to run the self-decompressing process in the emulator.
chris@portchris2:~/dynamips-0.2.5$ unzip -p c7200-advipservicesk9-mz.124-9.T.bin > image.bin
warning :27904 extra bytes at beginning or within zipfile
(attempting to process anyway)
chris@portchris2:~/dynamips-0.2.5$ file image.bin
image.bin: ELF 32-bit MSB executable, cisco 7200, version 1 (SYSV), statically linked, stripped
You can ignore the warning, unzip has just skipped the self-decompressing code at the beginning of the image.
Now, you can boot the image (in this example, no network connections are defined):
chris@portchris2:~/dynamips-0.2.5$ ./dynamips image.bin -t npe-400 -p 1:PA-A1 -p 2:PA-8T -p 3:PA-4E -p 4:PA-POS-OC3 -p 6:PA-FE-TX

OpenfilerOpenfiler is a powerful, intuitive browser-based network storage software distribution. Openfiler delivers file-based Network Attached Storage and block-based Storage Area Networking in a single framework.
Openfiler uses the rPath Linux metadistribution. It is distributed as a stand-alone Linux distribution. The entire software stack interfaces with third-party software that is all open source.
File-based networking protocols supported by Openfiler include: NFS, SMB/CIFS, HTTP/WebDAV and FTP. Network directories supported by Openfiler include NIS, LDAP (with support for SMB/CIFS encrypted passwords), Active Directory (in native and mixed modes) and Hesiod. Authentication protocols include Kerberos 5.
Openfiler includes support for volume-based partitioning, iSCSI (target and initiator), scheduled snapshots, resource quota, and a single unified interface for share management which makes allocating shares for various network file-system protocols a breeze.
The following are just some of the features currently available (unless indicated otherwise) in Openfiler.
