yang模型

• 使用RFC7950中给的例子,container中包含LIST

module example-a {
  yang-version 1.1;
  namespace urn:example:a;
  prefix a;

  container a {
    list b {
      key id;
      leaf id {
        type string;
      }
      notification down {
        leaf reason {
          type string;
        }
      }
      action reset {
        input {
          leaf delay {
            type uint32;
          }
        }
        output {
          leaf result {
            type string;
          }
        }
      }
    }
  }
  notification failure {
    leaf b-ref {
      type leafref {
        path "/a/b/id";
      }
    }
  }
}

• 安装到sysrepo

root@bfa784c0263a:~/netconf_src/bak_sysrepo/build/examples# sysrepoctl -i example-a.yang 
root@bfa784c0263a:~/netconf_src/bak_sysrepo/build/examples# sysrepoctl -l | grep example-a
example-a                     |            | I     | root:root | 600         |            |                                                                        
root@bfa784c0263a:~/netconf_src/bak_sysrepo/build/examples# 

运行netopeer2

• 终端1首先运行netopeer2-server

root@bfa784c0263a:~/netconf_src/bak_sysrepo/build/examples# netopeer2-server -d -v2

• 另开一个终端2，创建一个xml的配置文件,向b这个list里写入两个实例

root@bfa784c0263a:~# cat config1.xml 
<a xmlns="urn:example:a">
  <b>
    <id>1</id>
  </b>
  <b>
    <id>2</id>
  </b>
</a>
root@bfa784c0263a:~# 

• 终端2启动netopeer2-cli，连接到server

root@bfa784c0263a:~# netopeer2-cli   
> connect localhost
Interactive SSH Authentication
Type your password:
Password: 
> edit-config --target running --config=./config1.xml
OK
> 

• 终端2上使用config1.xml 来edit running config，默认是merge

> edit-config --target running --config=./config1.xml
OK
> 

• 终端2上查看(指定xpath)

> get-config --source running --filter-xpath /a/b
DATA
<data xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <a xmlns="urn:example:a">
    <b>
      <id>1</id>
    </b>
    <b>
      <id>2</id>
    </b>
  </a>
</data>

• 终端3上创建一个config2.xml,只包含一个实例

root@bfa784c0263a:~# cat config2.xml    
<a xmlns="urn:example:a">
  <b>
    <id>1</id>
  </b>
</a>
root@bfa784c0263a:~# 

• 终端2上用config2.xml来edit running config,op设置为replace

> edit-config --target running --config=./config2.xml --defop replace
OK
> 

• 终端2上可以看到只剩"1"了

> get-config --source running --filter-xpath /a/b
DATA
<data xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <a xmlns="urn:example:a">
    <b>
      <id>1</id>
    </b>
  </a>
</data>
