Workingdir = /Users/gregferro/Documents/GNS/BE-WAN-Emulator-V1.1_working This text spawns another dynamips instance on the IDP port specified. GNS3 will put the following text into the. This is because Setup Mode uses all available CPU cycles and will cause your IDLEPC value to be wrong for normal use. You need to connect to the router and move out of the of Setup mode. Setting the IDLEPC valueĭrag the router model that you configured in the previous section onto the screen and click the play button to start the emulator. In fact, I would typically only use a single router and a single image for all my GNS3/Dynagen use. You can have multiple images for a platform, but if you are using sparsemem (as I recommend you should to save memory), then run the same image for every router. We will set the IDLEPC in the next section but you need to leave it blank for now. You must click Save to write the parameters and it will look like: Users/gregferro/Documents/GNS/IOS/1.image I prefer to create a GNS directory in my Documents and a sub-directory for IOS. Point the Image file: to the directory where you IOS images are are stored.

Press Shift-?-I or use the Menu, Edit, IOS Images and Hypervisors to get this screen:Ĭonfiguring the Dynagen parameters.(Click for a full size image) We need to tell Dynamips where the IOS image is. The C3700 is probably your seond best bet.

Your best bet is to use 7200 series images, but also the C1700, C2600, C2691, C3600 and C3700 families used MIPS CPU’s. This means most of the older routers, and not many of the new ones. Which IOS image should you use ?īecause dynagen is an emulator for the MIPS CPU, you can only images that run on Cisco router hardware that uses the MIPS processor. This makes sure you don’t confuse it with a ‘normal’ image. When unzip the file, it is a convention to rename it with a.

For those images that use mzip compression, you can download the Zipeg software which supports mzip.

l – the image will be relocated at run timeĪnd the second letter tells you what the compression type is:įor most images, ZIP compression is used and you can use a standard software package.

Today, RAM is cheap so the flash image is always copied to memory at boot time.) That is, the program was always executed from Flash, not form memory. (in the olden days, RAM was also expensive and the image would often run from flash, and only dynamic information was stored in RAM. The first letter tells you whether the image runs from flash, memory or ROM. For the following filename, the letters MZ are the key: The IOS image name will tell you which compression is being used. When using GNS3/Dynagen, you can save startup time by uncompressing the IOS images.Ĭisco IOS images are compressed using one of three formats, zip, mzip or STAC. As a result, IOS was compressed and the first thing IOS usually does these days on startup is to uncompress the image from Flash to RAM. Historically, flash memory was expensive and not very large. Working and Unzipping IOS ImagesĬisco IOS images are compressed so as to use the least amount of flash memory. This is becuase the binary that emulates the PIX/ASA has only been compiled for the Windows and Linux platforms.

PEMU does not work on MAC OS X (as far as I know and these settings make no difference.). I haven’t used this feature as yet and may post something on this in the future.
