7200 模拟器的帮助文件
Authors: Fabien Devaux, Christophe Fillot, MtvE Emulated hardware
（作者简介）
By default, a NPE-200 is emulated. You can choose 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.
缺省情况下，NPE-200 被模仿。你可以通过“-t”选择NPE 形式。"npe-100", "npe-150",
"npe-175", "npe-200", "npe-225", "npe-300" and "npe-400"等等这些形式都可以选择。注意：
“NEP-g1”模式不可实现。
Please note that you must use the C7200-IO-FE PA driver as IO card if you want a
FastEthernet interface in slot 0.
请注意如果你想在slot0 模块放置快速以太网口你必须使用“C7200-IO-EF PA”驱动程序
作为IO 卡
For other slots, you must use the PA-FE-TX driver.
如果是其他的slot，你必须使用“PA-FE-TX”的驱动程序

Virtual Bridge 虚拟桥接
The virtual bridge is used to emulate a shared network between emulator
instances.Any emulator instance can ast as a virtual bridge.
虚拟桥接被用来在模拟器之间模拟一个共享网络
例如：任何模拟器可以被当作一个虚拟的桥接
The configuration file (specified by the "-b" option) contains a list of NetIO descriptors, which the
following 配置文件（-b 命令可以列出）包括一个netIO 描述符列表，如下
syntax: netio_type[:netio_parameters]
语法：netio-type
Example: # Connection to instance "I0" 连接I0
udp:10000:127.0.0.1:10001
# Connection to instance "I1"
udp:10002:127.0.0.1:10003
# Connection to instance "I2"
udp:10004:127.0.0.1:10005
The "I0" would be launched with the following parameters:
I0 将以下面的参数开始
dynamips ios.bin -p 1:PA-FE-TX:udp:10001:127.0.0.1:10000
Virtual ATM switch 虚拟ATM 交换机
******************
The virtual ATM switch fabric is used to emulate an ATM backbone between
emulator instances. The use of this virtual switch is not mandatory, you
can directly connect emulator instances for point-to-point ATM connections.
Please note that only basic VP/VC switching is supported, there is no
support for ILMI/QSAAL/... or other specific ATM protocols.
虚拟ATM 交换机过去习惯被模拟成一个在模拟器设备之间的ATM 骨干网。虚拟交换机的
使用不是强制的，你可以直接把模拟器直接成点对点的ATM连接。请注意，仅仅基础VP/VCb
被模拟器支持，对于其他的ATM 协议并不支持。
Any emulator instance can act as a virtual ATM switch.
模拟器可以被当作一台虚拟ATM 交换机
Example of configuration file (specified by the "-a" option):
配置实例（－a 命令可以列举出）
# Virtual Interface List
IF:A0:udp:10001:127.0.0.1:10000
IF:A1:udp:10002:127.0.0.1:10003
IF:A2:udp:10004:127.0.0.1:10005
# VP connection between I0 and I1
VP:A0:10:A1:20
VP:A1:20:A0:10
# VP connection between I0 and I2
VP:A0:11:A2:30
VP:A2:30:A0:11
# VC connection between I1 and I2
VC:A1:5:2:A2:7:3
VC:A2:7:3:A1:5:2
In this example, we have 3 virtual interfaces, A0, A1 and A2. The syntax
for interface definition is similar to Port Adapters:
在这个例子中，有三个虚拟接口，A0，A1，A2。
IF:interface_name:netio_type[:netio_parameters]
You can do VP switching or VC switching:
你还能做VP 交换或者VC 交换
1) VP switching
syntax: VP:input_if:input_vpi:output_if:output_vpi
2) VC switching
syntax: VC:input_if:input_vpi:input_vci:output_if:output_vpi:output_vci
Testing the Virtual ATM switch with one dynamips instance
*********************************************************
(Contribution of Mtv Europe)
Virtual ATM switch configuration file ("atm.cfg"):
IF:A0:udp:10003:127.0.0.1:10001
IF:A1:udp:10004:127.0.0.1:10002
# a0/vpi=1/vci=100 connects to a1/vpi=2/vci=200
VC:A0:1:100:A1:2:200
VC:A1:2:200:A0:1:100
Invoking dynamips:
./dynamips -p 1:PA-A1:udp:10001:127.0.0.1:10003 -p 2:PA-A1:udp:10002:127.0.0.1:10004 -a
atm.cfg IOS.BIN
(note input ports of IOS interfaces are output ports of ATM switch
interfaces, and vice versa).
IOS configuration:
ip cef
ip vrf test
rd 1:1
route-target both 1:1
int a1/0
no shut
int a1/0.2 p
ip addr 1.1.1.1 255.255.255.0
pvc 1/100
interface a2/0
no shut
interface a2/0.2 p
ip vrf forwarding test
ip addr 1.1.1.2 255.255.255.0
pvc 2/200

# ping 1.1.1.2

Virtual Frame-Relay switch 虚拟帧中继交换机
**************************
The virtual Frame-Relay switch fabric is used to emulate a Frame-Relay
backbone between emulator instances. The use of this virtual switch is not
mandatory, you can directly connect emulator instances with appropriate IOS
configuration.
虚拟帧中继交换机构造过去习惯于被模拟成一个模拟器之间的帧中继骨干。虚拟交换机的使
用不是强制的，你可以用适合的IOS 直接连接模拟器设备
Any emulator instance can act as a virtual Frame-Relay switch.
任何模拟器可以当作成一个虚拟帧中继交换机
There is only a basic implementation of the LMI protocol (ANSI Annex D), which isprobably not
conforming but works with Cisco IOS. Fortunately, Cisco IOS is able to detect automatically the
LMI protocol.
这儿仅仅有一个基础的LMI 协议设备，这样的设备不可能一致但是却能用IOS 工作，幸运
的是，cisco IOS 能自动选择LMI 协议
Example of configuration file (specified by the "-f" option):
配置例子
# Virtual Interface List
IF:S0:udp:10001:127.0.0.1:10000
IF:S1:udp:10002:127.0.0.1:10003
# DLCI switching between S0 and S1
VC:S0:200:S1:100
VC:S1:100:S0:200
In this example, we have 2 virtual interfaces, S0 and S1. The syntax for interface definition is
similar to Port Adapters:
在这个例子中，有两个虚拟接口，s0 和s1。端口定义的构造与端口适配器很接近。
IF:interface_name:netio_type[:netio_parameters]
IF：接口名称
DLCI switching syntax:
DLCI 交换构造
VC:input_if:input_dlci:output_if:output_dlci
VC：进入接口：进入_DLCI 出口接口：出口_DLCI
In the example above, the switch is configured to switch packets received on interface S0 with
DLCI 200 to interface S1 with DLCI 100, and vice-versa.
在上面的例子中，交换机被配置为被接收到的包——从DLCI200 的s0 接口到DLCI 100 的
S1 接口，反之亦然。
