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

HOST='192.168.0.87'

PORT='8088'

# set timeout value for ncclient

export NCCLIENT_TIMEOUT=90

[root@desk yang-explorer]# ls

default-models  docs  env.sh  LICENSE  README.md  requirements.txt  server  setup.sh  start.sh  v  YangExplorer

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

Subscript

 

4、配置XE路由器

XE3(config)#netconf-yang      //主要配置

 

image_5d2f5487_64b0

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

                                                                                                      ip---->address-choice

image_5d2f5487_2eb0

<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
