Emulatedhardware
（作者简介）
By default, aNPE-200 is emulated. You can choose the NPE type with the"-t" option.It is
possible toselect "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 notethat you must use the C7200-IO-FE PA driver as IO card if you want aFastEthernet 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-TXdriver.
如果是其他的slot，你必须使用“PA-FE-TX”的驱动程序

Virtual Bridge

instances.Any emulator instance can ast asa 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 thefollowing
配置文件（-b命令可以列出）包括一个netIO描述符列表，如下

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 withthe following parameters:
I0将以下面的参数开始

Virtual ATM switch
虚拟ATM交换机
******************
The virtual ATM switch fabric is used toemulate an ATM backbone between
emulator instances. The use of this virtualswitch is not mandatory, you
can directly connect emulator instances forpoint-to-point ATM connections.
Please note that only basic VP/VC switchingis supported, there is no
support for ILMI/QSAAL/... or otherspecific 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 virtualATM switch.
模拟器可以被当作一台虚拟ATM交换机
Example of configuration file (specified bythe "-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 virtualinterfaces, A0, A1 and A2. The syntax
for interface definition is similar to PortAdapters:
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 onedynamips 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 toa1/vpi=2/vci=200
VC:A0:1:100:A1:2:200
VC:A1:2:200:A0:1:100
Invoking dynamips:
./dynamips -p1:PA-A1:udp:10001:127.0.0.1:10003 -p 2:PA-A1:udp:10002:127.0.0.1:10004 -aatm.cfg IOS.BIN
(note input ports of IOS interfaces areoutput ports of ATM switch
interfaces, and vice versa).
IOS configuration:
ip cef
ip vrf test
rd1:1
route-targetboth 1:1
int a1/0
noshut
int a1/0.2 p

Virtual Frame-Relay switch
虚拟帧中继交换机
**************************
The virtual Frame-Relay switch fabric isused to emulate a Frame-Relay
backbone between emulator instances. Theuse of this virtual switch is not
mandatory, you can directly connectemulator 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 virtualFrame-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 theLMI protocol (ANSI Annex D), which isprobably not conforming but works withCisco IOS. Fortunately, Cisco IOS
isable 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 bythe "-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 virtualinterfaces, S0 and S1. The syntax for interface definition is similar to PortAdapters:
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 configuredto switch packets received on interface S0 with DLCI 200 to interface S1 withDLCI 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DLCI100的S1接口，反之亦然。
