In the admin panel, the subnet page shows that the available IP is less than 0

We create 5 ports in advance，Then edit the subnet and set the range of the allocation_pools value to 10.10.10.3-10.10.10.4，We will find that the available ip becomes negative

Is this a problem of horizon? If the neutron API returns a negative value, it should be fixed in neutron rather than horizon.

[pengyuesheng (pengyuesheng)]

No,The result is calculated by horizon, not neutron API returns

    Adjusts subnet_free_ips to 0 when it is negative

    Subnet_free_ips is negative if the subnet's allocation_pools
    range is less than the used IPs of the subnet.
    This patch adjusts subnet_free_ips to 0 when it is negative.
