Dynamips 0.2.8 RC2

Help for Cisco router simulator (dynamips-0.2.8) ================================================ Authors of this document: Fabien Devaux, Christophe Fillot, MtvE Emulated hardware ***************** The emulator currently supports the following platforms: - Cisco 7200 (NPE-100 to NPE-400) - Cisco 3600 (3620, 3640 and 3660) - Cisco 2691 - Cisco 3725 - Cisco 3745 - Cisco 2600 (2610 to 2650XM) - Cisco 1700 (1710 to 1760) By default, a Cisco 7206VXR with NPE-200 (256 Mb of DRAM) is emulated. To emulate another platform, use the "-P" command line option (for example, "-P 3725" or "-P 3600"). For the 7200, you can change the NPE type with the "-t" option. It is possible to select "npe-100", "npe-150", "npe-175", "npe-200", "npe-225", "npe-300" and "npe-400". The "npe-g1" is not working. For the 3600, a 3640 with 128 Mb is emulated by default. You can change this with the "-t" option and by specifying "3620" or "3660". Don't forget to set the chassis type depending on your IOS image, a c3660 image will not run on c3640 hardware and vice-versa. Remark: PCMCIA card emulation is not supported yet with Cisco 3600.

Alter the value to match the CISCO clock with the real time. The command "show clock" at the IOS' CLI will help you set this value. --idle-pc <pc> : The "idle PC" feature allows you to run a router instance without having a 100% CPU load. This implies that you can run a larger number of instances per real machine. To determine the "idle PC", start normally the emulator with your Cisco IOS image, and a totally IOS empty configuration (although not mandatory, this will give better results). When the image is fully booted, wait for the "Press RETURN to get started!" message prompt, but do not press Enter key. Wait about 5 seconds, then press "Ctrl-] + i". Some statistics will be gathered during 10 seconds. At the end, the emulator will display a list of possible values to pass to the "--idle-pc" option. You may have to try some values before finding the good one. To check if the idle PC value is good, just boot the Cisco IOS image, and check your CPU load when the console prompt is available. If it is low, you have found a good value, keep it preciously. Important remarks: ================== * An "idle PC" value is *specific* to a Cisco IOS image. You cannot boot a different IOS image without proceeding as described above. * Do not run the process while having the "autoconfiguration" prompt. --exec_area <size> : The exec area is a pool of host memory used to store pages translated by the JIT (they contain the native code corresponding to MIPS code pages).
