华为模拟器ensp最新（华为模拟器eNSP学习笔记）4.安装wireshark ，选择完全安装3.安装win pcap（注意，前面的勾必须勾选）安装方法：1.下载ensp软件。该软件为免费软件，可以在华为官网下载-技术支持 -工具 -企业网络 -eNSP-eNSP V100R002C00B39下载；2.打开下载好的软件包，双击安装程序，然后选择安装目录，勾选所有安装项（注意，必须勾选，其中wireshark 为抓包工具）
一、ensp的安装
随着华为网络设备的越来越多的使用，学习华为网络路由知识的人也越来越多，一款可以很好模拟路由交换的软件可以让你更好的完成各种实验，eNSP软件，就是你需要的。
工具：
电脑、eNSP安装包
安装方法：
1.下载ensp软件。该软件为免费软件，可以在华为官网下载-技术支持 -工具 -企业网络 -eNSP-eNSP V100R002C00B39下载；
2.打开下载好的软件包，双击安装程序，然后选择安装目录，勾选所有安装项（注意，必须勾选，其中wireshark 为抓包工具）
3.安装win pcap（注意，前面的勾必须勾选）
4.安装wireshark ，选择完全安装
5.安装Oracle VM 选择完全安装
6.安装完成，每次都要先启动Oracle VM，再启动ensp。不然网络无法配置。
二、ensp模拟器实验笔记：vlan不同接口类型的应用
路由器隔离广播域 交换机隔离冲突域 在交换机上怎么样隔离广播域呢？划分vlan！而vlan的接口类型有三种：一：access接口；看到这个单词是否特别熟悉 前面我们使用二层接口配ip时配不了一直报错，我们怎么解决的：port（接口） link（关联）-type（属性） access；（将接口类型设置为access）英文学的不好 反正我是这样理解的，如果有有错误请网友指正啊！第二种种类型是：trunk ；vlan id的取值范围是0到4095 ， 可以配置的值是1到4094，0和4095都是保留值，为什么保留呢？不知道，有知道的网友请在下方评论。access我们之前使用过这里不做介绍，如果有不知道的朋友请参考华为模拟器ensp实验学习笔记。使用 vlan bath 3 4 可以快速创建多个vlan
trunk端口是干什么用的呢？我们知道划分vlan之后每个vlan中的PC设备是可以互相访问的，但是不同的vlan间是无法访问的。trunk可以配置干道链路（trunk link）用作不同vlan 不同交换机之间的数据交互。trunk可以配置属于多个vlan。
dis vlan summ 查看vlan简要信息
第三种：hybrid接口：它实现对vlan的灵活应用 既有access的功能也有trunk接口的功能trunk接口实验在调试交换机的时候它的信息中心会一直提示你 关闭提示的命令 undo terminal monitor （在用户模式下)
实验如上图所示将pc1&pc3划分为vlan 1
将pc2&pc4划分为vlan 2
s1配置如下<Huawei>undo t

s2和s3和s1的配置方法相同配置之后我们可以使用dis port vlan来查看vlan接口的类型
设置好之后我们来试试同一vlan下的pc1和pc3是否能通讯
很明显不能
现在就是使用trunk接口的时候了 我们在s1上将g0/0/1口设置为trunk

[s1-GigabitEthernet0/0/1]port trunk allow-pass vlan 1 2 【让trunk这个接口可以通过vlan1数据也可以通过vlan2】
[s1-GigabitEthernet0/0/1]
同理在s2上进行同样的设置 在s3上将g0/0/1和g0/0/2都设置为trunk 在s3上设置时差别在于写允许通过vlan数据时 port trunk allow-passvlan all（允许所有的vlan数据通过）做完后我们来测试pc1与其他pc间的通讯

在测试的时候若发现pc1 ping不通其他的设备 请检查vlan的接口时否时trunk 查看命令：dis port vlan
若不是请使用undo删除vlan 再进行重新设置

现在来测试
不通！！然后又ping了网关 还是不通！
然后我就查看了vlan1的接口配置。发现：
[s1-Ethernet0/0/1]dis this
#
interface Ethernet0/0/1
port link-type trunk
port trunk allow-pass vlan 2 to 4094
#
它配置为trunk类型之后 通过的数据是从vlan2开始的 不是从vlan1
所以重新创建了vlan4
然后再各个设备上重新设置之后
重新测试数据时候能够正常通讯
ok完成
