Cisco IOS for Dynamips, Dynagen and GNS3 - December 2009

This is my collection of Cisco IOS for use with Dynamips.

The originals .bin files has been unzipped and renamed to .image, and recompressed with RAR to save disk space. Dynamips works better with an unzipped IOS, the router boot faster. You need to decompress the file with WinRar, UnRar, 7Zip, etc, to obtain the .image file and store it in the image folder.

This compilation includes several IOS for PIX (IOS and ASDM) and special IOS called Pagent and Callgen.

Pagent is a set of data networking test tools, based on the Cisco IOS (Internetwork Operating System) and developed within Cisco. The test tools are included in special IOS Pagent images.

Callgen is a set of Voice-Over-IP networking test tools, based on the Cisco IOS and developed within Cisco. The test tools are included in special IOS Callgen images.

The primary function of the Pagent and Callgen toolsets is to provide cost effective test tools to the Cisco testing community. The secondary function is to provide testing capabilities that are not available anywhere else and can be used in customer environments. One essential function is to generate valid simulated traffic necessary for testing networks under stress. The tools are not able to test the physical network layer and some parts of the data-link layer; that is, they can not affect frame checksums, preambles, inter frame gap times, inject hardware failures, or transmit invalid packet sizes.

The Pagent programs are best used for testing layer 3 protocols and above; that is, emulating routing protocols, multicast, TCP sessions and HTTP sessions.

Pagent is an enhanced Cisco IOS image that contains both Advanced IP or IP Base Services and the IP traffic generation tools. Pagent generates realistic traffic and bottlenecks to test QoS features such as IP Classification, IP Marking, and Queuing.

CallGen is a Cisco IOS-based bulk call generation tool implemented through extensions to the regular Cisco IOS image, which provides commands and utilities used to simulate originating and terminating calls on routers and access servers.

The file "Patch for Dynamips.txt" contains the instructions for patch Dynamips (for use with Dynagen or GNS3) to use this IOS.

In every folder, the TXT file includes the description of all IOS: name, features and RAM memory in Mb.
