SoftLayer API以了解VLAN中的总数和可用IP

您好，

如果我知道VLAN ID，可以使用哪个API来了解VLAN的总IP和已使用/可用的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，因此我必须获得VLAN的总IP和可用IP的总和。不确定这是否正确。

由于

Answer 1

请尝试以下方法：

 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关联的子网检索与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

您还可以看到上述请求的“子网”部分中显示的数据的含义，即：

totalIpAddresses：此子网中包含的IP地址数。

usefulIpAddressCount：此子网内可以寻址的IP地址数。

Answer 2

要使用总使用/可用IP获取有关其子网的vlan的信息，请尝试以下Python脚本。

此脚本将有助于从vlan中的子网获取确切的空闲插槽数。

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