But once you have run through the вЂњIdle-PCвЂќ process for a given IOS image, CPU utilization decreases drastically. it initially has no way of knowing when the virtual routerвЂ™s CPU is idle so it dutifully executes all the instructions that make up IOSвЂ™s idle routines just as it would execute the instructions that perform вЂњrealвЂќ work. Before we list the best Windows emulators for Mac, letвЂ™s understand how it works.

There are plenty of such apps available for Mac OS, which work great. If you have plenty of RAM, and you know what you are doing, set вЂњmmap = falseвЂќ in the device default or router sections of your labs to disable mmap for those instances.Дynamips also uses a lot of CPU, because it is emulating a routerвЂ™s CPU instruction-by-instruction. To run Windows apps on a Mac computer, you will need an emulator or a virtualization tool. (See the Memory Usage Optimizations section for configuration options that can signficanly reduce memory utilization). Your OS will naturally cache in RAM the sections of the mmap files that are being used. In the working directory you will see temporary вЂњramвЂќ files equal to the size of the virtual routersвЂ™ RAM size. This is because by default Dynamips uses memory mapped files for the routersвЂ™ virtual memory. This will be the total working set size by default the amount of your systemвЂ™s actual RAM used will typically be significantly less. Dynamips also allocates (by default) 64 MB of RAM / instance on Unix systems (16 MB on Windows systems) to cache JIT translations. If you intend to run an IOS image that requires 256 MB of RAM on a real 7200 router, and you devote 256 MB of RAM to your virtual router instance, it will allocate 256 MB of working set memory.

Quickly check configurations to be deployed later on real routers.Дynamips uses a fair amount of RAM and CPU in order to accomplish its emulation of the MIPS processor.

Test and experiment features of Cisco IOS.

It would allow people to become more familiar with Cisco devices, Cisco being the world leader in networking technologies.

Be used as a training platform, with software used in real world.The source code is licensed under the GNU GPL.ДЄccording to Fillot, the creator, this kind of emulator would be useful to: Another popular add-on is GNS3, a graphical front end for Dynamips and Dynagen. One of the most popular is Dynagen, which is a front-end add-on that allows the use of an INI configuration file to provision Dynamips emulator networks. ДЄlthough Dynamips original development has been stalled since version 0.2.8-RC2, released in October 2007, development continues through the efforts of the GNS3 project and its volunteers Dynamips is now up to version 0.2.14-dev on Windows, Linux and OS X, and version 0.2.8-RC2 on Solaris.

Dynamips runs on FreeBSD, Linux, Mac OS X or Windows and can emulate the hardware of the Cisco series routing platforms by directly booting an actual Cisco IOS software image into the emulator. It has been created by Christophe Fillot who started his work in August 2005.

Dynamips is an emulator computer program that was written to emulate Cisco routers.
