[CENTER]Cisco 7200 Simulator

[LEFT] Introduction:

The goals of this emulator are mainly:[list]
[*]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.[/list:u]Of course, this emulator cannot replace a real router: you should be able to get a performance of about 1 kbps (depending on your host machine), to be compared to the 100 kbps 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):[list]
[*]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).[/list:u]The following Cisco 7200 Port Adapters (PA) are currently supported:[list]
[*]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)[/list:u]The following Cisco 3600 Network Modules (NM) are currently supported:[list]
[*]Ethernet cards: "NM-1E", "NM-4E" and "NM-1FE-TX", all based on AMD Am79c97x chips
[*]Serial card "NM-4T"[/list:u]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.

[URL="http://dyna-gen.sourceforge.net"]Dynagen[/URL] (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 [URL="http://dyna-gen.sourceforge.net/tutorial.htm"]tutorial[/URL] (http://dyna-gen.sourceforge.net/tutorial.htm).

[URL="http://dynagui.sourceforge.net"]Dynagui [/URL](http://dynagui.sourceforge.net/) is a graphical front-end written by Yannick Le Teigner. It uses Dynagen to communicate with the hypervisor.

I have personally tested this and working on this. This is real great thing and Open Source .... Full Package is available here.

Plz write down the installation procedure or steps of above softwares including front end , according to ur experience so that it might be easy for other people to learn

[AjEe]

Infact a tutorial is already written on this and i just noticed they have a new domain and website for that... SO you can get everything info from there..
