Example of PCI identifiers and interface names
The following example shows the relationship between PCI identifiers, ports, and interface names.
In this example, PCHIDs 01ec and 01ed represent the two ports of the same adapter in direct mode.
| FID | PCI ID | PCHID | VF | Interface |
|---|---|---|---|---|
| fa | 1ec0:00:00.0 | 01ec | n | eno7872np0 |
| fb | 1ec0:00:00.2 | 01ec | y | eno7872v0 |
| fc | 1ec0:00:00.3 | 01ec | y | eno7872v1 |
| 62 | 1ec0:00:00.1 | 01ed | n | eno7888np1 |
| 5f | 1ec0:00:10.1 | 01ed | y | eno7888v0 |
| 63 | 1ec0:00:10.2 | 01ed | y | eno7888v1 |
Explanation
- All devices share the same domain (
1ec0) 00:00.0and00:00.1are PFs- The
<device>.<function>part is the resource ID, which distinguishes PFs and VFs within the same domain. - Interface names encode PF identity and VF index
