思科路由器仿真器,用来仿7200系列得,可以在电脑上模拟路由器-Cisco router simulator, used to fake a 7200 series can be simulated

Description of the hypervisor mode
==================================

The hypervisor mode of dynamips allows you to run simultaneously
many virtual router instances, and to simulate ATM, Ethernet
or Frame-Relay networks. 

Running dynamips in hypervisor mode
===================================

dynamips -H <tcp_port>

Managing the hypervisor
=======================

You can connect directly to the TCP control port with telnet, or use
dynagen/dynagui that will pass commands transparently. The second method
is highly recommended.

The command syntax is simple: <module> <function> [arguments...]
For example: "c7200 start R1" starts virtual instance named "R1".

The modules that are currently defined are given below:

  * hypervisor : General hypervisor management
  * vm         : General virtual machine (VM) management
  * c7200      : Virtual instances of Cisco 7200
  * c3600      : Virtual instances of Cisco 3600
  * nio        : Network Input/Output (NIO) descriptors
  * nio_bridge : NIO bridges (shared media)
  * atmsw      : ATM switches
  * frsw       : Frame-Relay switches
  * ethsw      : Ethernet switches


Hypervisor management module ("hypervisor")
============================================

* "hypervisor module_list" : Display the module list.

* "hypervisor cmd_list <module>" : Display commands recognized by the
  specified module.

* "hypervisor close" : Close the current session.

* "hypervisor stop"  : Destroy all objects and stop hypervisor.

* "hypervisor reset" : Destroy all objects (used to get an empty 
  configuration)

* "hypervisor working_dir <directory>" : Set the directory to use to store
  files.

* "hypervisor save_config <filename>" : Save the configuration of all objects
  into the specified file.


Virtual Machine module ("vm")
=============================

* "vm list" : List all VM instances (c7200, c3600).

* "vm set_debug_level <instance_name> <level>" : Set the debug level
  (which is a number) for a VM. By default, no specific debug is enabled
  (level = 0).

* "vm resume <instance_name>" : Resume execution of the instance.

* "vm set_clock_divisor <instance_name> <clock_div>" : Set the clock

  Counter (PC). You must determine it through the method explained in the
  main README file.

* "vm set_exec_area <instance_name> <area_size>" : Set the exec area

  cannot get access to the console.

  to use for AUX port. By default, no TCP port is chosen, meaning that you
  cannot get access to the AUX port.
