2、安装yang-explorer
准备：
MAC、Linux（不支持windows)
python 2.7
pip软件管理器
浏览器带flash plugin（推荐chrome）
//pip install --upgrade pip
//yum install python-virtualenv
//yum install graphviz
a、更改pip源
mkdir ~/.pip
vi ~/.pip/pip.conf
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = mirrors.aliyun.com
yum install python2-pip python-virtualenv graphviz -y
依赖组件：
yum install libxml2-devel libxslt-devel python-devel zlib-devel gcc git -y
git clone https://github.com/CiscoDevNet/yang-explorer.git
b、安装
cd yang-explorer/
bash setup.sh

c、修改配置文件并运行yang-exporer
[root@desk yang-explorer]# cd server/static/
[root@desk static]# vi YangExplorer.html
var swfVersionStr = "16.0.0";
// To use express install, set to playerProductInstall.swf, otherwise the empty string.
var xiSwfUrlStr = "expressInstall.swf";
var flashvars = {};
flashvars.host = '192.168.0.87'; //修改监听地址和端口
flashvars.port = '8088';
[root@desk static]# cd ..
[root@desk server]# cd ..
[root@desk yang-explorer]# vi start.sh
#!/usr/bin/env bash

3、导入YangModels
点击Login

</rpc-reply>
检查
XE3#sh ip inter b
