这是 Juniper Router 配置的一部分，它代表 vlan：

     family inet {
                address 3.189.239.238/29;
                address 3.189.239.254/28;
            }
        }
        unit 472 {
            vlan-id 472;
            family inet;
        }
        unit 473 {
            vlan-id 473;
            family inet;
        }
        unit 474 {
            vlan-id 474;
            family inet {
                address 3.57.110.6/29;
            }
---(more 54%)---

        }
        unit 475 {
            vlan-id 475;
            family inet {
                address 3.57.110.14/29;
            }
        }
        unit 476 {
            vlan-id 476;
            family inet {
                address 3.57.110.22/29;
            }
        }
        unit 480 {
            vlan-id 480;
            family inet {
                address 1.246.212.14/28;
            }

它怎么能像API一样提供出来？然后我可以从网站获取所有 vlan 信息。

有没有像 SNMP 协议那样提供 vlan 信息的方法？
