Interfaces are named in several ways, depending on their type: physical, vif, or VLAN.
Physical interfaces are automatically assigned names based on the slot where the network adapter is installed.
The vif interface names are user specified. A vif interface can have any name that meets these criteria:
VLAN-interface-names:
<physical-interface-name>-<vlan-ID>
<vif-interface-name>-<vlan-ID>
Ethernet adapters can support one, two, or four ports. Ethernet interfaces are identified by a name consisting of "e", the slot number of the adapter, and the port on the adapter (if multiported adapter). A multiport adapter will have letters or numbers imprinted next to its ports.
The following table lists interface types, interface name formats, and example of names that use these identifiers.
| Interface type | Interface name format | Examples of names |
|---|---|---|
| Physical interface single port | e | e0 e1 |
| Physical interface multiple port (two or four ports) | e | e0a e0b e0c e0d e1a e1b |
| vif | Any user-specified string that meets the criteria specified in the Prerequisites section of the Creating a single-mode vif page. |
