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. |
