Field af_type from API ```/dataservice/data/device/statistics/interfacestatistics provides four different values based on our data (version 20.6.4).
Few questions We need an explanation of all four value, specifically for IPv46 and None
- For IPv4 it seems interface is type of IPv4.
- For IPv6 it seems interface is type of IPv6.
- Are there any more possible values of af_type?
Thanks!
