SoftLayer API 了解 VLAN 中的总 IP 和可用 IP

Question

您好，

如果我知道 VLAN ID.

可以使用哪个 API 来知道总 IP 和 VLAN 的 used/usable IP

我能想到的一种方法是我可以获得 VLAN 的子网，然后在子网详细信息中我可以看到具有 "totalIpAddresses,usableIpAddressCount" 属性的总 IP 和可用 IP。但是，由于 VLAN 具有多个子网，因此我将必须获得 VLAN 的总 IP 和可用 IP 的总和。不确定这是否正确。

谢谢

Answer 1

请尝试以下操作：

 https://[username]:[apikey]@api.softlayer.com/rest/v3/SoftLayer_Network_Vlan/[Vlan_id]/getObject?objectMask=mask[subnets[ipAddresses]]
Method: GET

或者，

如果您希望此请求通过 IP 的关联子网检索与 IP 地址关联的 VLAN：

URL:

https://[username]:[apikey]@api.softlayer.com/rest/v3/SoftLayer_Network_Vlan/getVlanForIpAddress?objectMask=mask[id, vlanNumber,networkSpace,primaryRouter]
Method: POST

Json:

{
  "parameters": [
    "10.41.160.194"
  ]
}

参考： getVlanForIpAddress

你还可以看到上面请求的'Subnet'部分显示的数据的含义，即：

totalIpAddresses:此子网中包含的 IP 地址数。

usableIpAddressCount: 可在该子网内寻址的 IP 地址数。

Answer 2

要获取有关其子网的 vlan 总 used/usable 个 IP 的信息，请尝试以下 Python 脚本。

此脚本将有助于从 vlan 内的子网中获取空闲插槽的确切数量。

This script retrieves the Total Ip Addresses, Usable Ip Address Count and Free Slots for an specific Vlan Id
