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

省略。。。。。。。

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

HOST='192.168.0.87'

PORT='8088'

# set timeout value for ncclient

export NCCLIENT_TIMEOUT=90

[root@desk yang-explorer]# ls

[root@desk yang-explorer]# ./start.sh

3、导入YangModels

点击Login

username：guest

password：guess

Subscript

4、配置XE路由器

XE3(config)#netconf-yang //主要配置

Cisco-IOS-XE-native----->native --->interface --->GigabitEthernet name

ip---->address-choice

<rpc-reply message-id="urn:uuid:79b79a13-844a-4248-aac5-c47401b15745" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0">

<ok/>

</rpc-reply>

检查

XE3#sh ip inter b

Interface IP-Address OK? Method Status Protocol

GigabitEthernet1 192.168.0.29 YES DHCP up up

GigabitEthernet2 10.1.1.1 YES other administratively down down

GigabitEthernet3 unassigned YES unset administratively down down

XE3#sh ip inter b

Interface IP-Address OK? Method Status Protocol

GigabitEthernet1 192.168.0.29 YES DHCP up up

GigabitEthernet2 10.1.1.1 YES other up up

GigabitEthernet3 unassigned YES unset administratively down down

产生python文件：
