Dynagen is a utility for use with the dynamips Cisco router simulator. It allows you to quickly provision and manage virtual networks using an INI like configuration file.
Guys do something for Switches. Thanks
Version 0.11.0 * Merge of the features of confDynagen (dynamic reconfiguration, pemu support, and many other features). Big thanks to Pavel Skovajsa for performing the merge work and other significant contributions. * Addition of a pemu server for Cisco PIX emulation. Thanks to Thomas Pani for writing the wrapper, and to mmm123 for writing pemu. NOTE: A Pemu instance will always consume 100% of a CPU core. There is no "idlepc". Use a tool like BES (Windows) or cpulimit (Linux) if you wish to reduce CPU usage. * Could not specify a model of 1751 or 1760 in a router definition * WIC interfaces on 1751s and 1760s could not be used * On Windows platforms, Network Device list changes to the temp dir before executing Dynamips (helps Vista users). * Added a delay option to start /all. This introduces a pause between starting devices. * Filter command was broken in 0.10.x * FS#217 - fixed the connect method for switches. Only effected 3rd party developers using the library, Dynagen does not use these methods. * FS#211 - Dynagen crash when specifying invalid port * 7200 instances now default to using an NPE-400 rather than an NPE-200. This is because the C7200-IO-2FE is not compatible with the NPE-200 and this was causing confusion. You can override this new behavior with "npe = NPE-200". * Referencing f0/0 or f0/1 with 7200s now automatically inserts a C7200-IO-2FE in slot 0 rather than a C7200-IO-FE. You can override this behavior by specifying "slot0=PA-C7200-IO-FE". * Support for ATM to Ethernet bridge introduced in Dynamips 0.2.8-RC2. Provision using ATMBR. * idlemax issue fixed (see http://7200emu.hacki.at/viewtopic.php?p=13676) * Resolves crash when invalid port specified on adapter (http://7200emu.hacki.at/viewtopic.php?p=15685) * Dynagen now warns if a router does not have an image set * The prefix "PA-" for the 7200 IO adapters is optional (i.e. "PA-C7200-IO-2FE" or "C7200-IO-2FE"). * Multisever config with two instances on the same system no longer requires use of the UDP configuration option workaround. * The adapter "PA-4T+" should now be specified as "PA-4T+". "PA-4T" is still supported so as not to break compatibility with existing labs. * Added a "start-pemu.sh" script to launch pemuwrapper, writing temp files to a temp directory. To be used on Linux systems. * Throws a warning for the infamous "using localhost with multiserver" misconfiguration. * Change of base udp port for pemuwrapper to 40000 so that we do not conflict with vpc * "idlepc show" now shows the current idlepc value if one has already been applied * idlepc commands now warn that pemu instances are not supported * Added "ghostsize" command to dynamic configuration mode * Ignores GNS3-DATA section. Caution: Issuing a "copy run start" from inside of Dynagen will obliterate this section.
