In papi (platform_api), these are tied to nic status as returned by the isi_net library. They are defined there as:  Up : up, valid, active Active : valid, activeNo Carrier : valid, not active Not Available : none/no device  Not Available means no device found, it is literally defined as "none" in code No Carrier basically means no Ethernet link, the card is not active if it does not have link. Active is the opposite, the card is plugged in and has link and is ready Up is a more specific version of Active, meaning it also has the Up flag, meaning it is administratively ready
The response from the following resource URL:  /platform/3/network/interfaces?describe has status in response with 4 possible values. I was wondering if anybody could mention what each of them mean exactly or point to a place where these are discussed in detail.  "status": {  "enum": [ "Up", "No Carrier", "Active", "Not Available" ], "type": "string", "description": "Status of the interface", "required": true }  Thanks, Aman
