The filer supports the following interface types:
Interface numbers are assigned based on the slot in which the interface card is installed. For more information about how network interfaces are numbered, refer to the hardware guide for your filer model.
Some Ethernet interface cards support four ports. These cards are referred to as quad-port interfaces. The filer uses a letter to refer to each port on a quad-port interface. The following table shows the relationship of port numbers to letters.
| Port number | Letter |
|---|---|
| 1 | a |
| 2 | b |
| 3 | c |
| 4 | d |
The following table shows how interfaces other than virtual interfaces are named, and how interface names are combined with card slot numbers and port letters to make their names unique.
| Interface type | Letter used in name | Examples of names |
|---|---|---|
| Ethernet (single) | e |
e0 e1 |
| Ethernet (quad-port) | e |
e0a e0b e0c e0d e1a e1b |
| FDDI | f |
f0 f1 |
| ATM | a |
a0 a1 |
The name of a virtual interface is a string that is no longer than 15 characters that meets the following criteria:
Virtual interface names are case-sensitive.
When you write or modify shell scripts that involve interface names, remember the interface naming conventions that the filer uses. Because the slot in which an interface card is installed is a part of the interface name, different filers might have different interface names.
The first time the setup program runs, the filer creates a host name for each installed interface by appending the interface name to the host name.
A filer named toaster with a single Ethernet interface in slot 0 and a quad-port Ethernet interface in slot 1 has the host names given in the following table.
| Interface | Host name |
|---|---|
| Single-port Ethernet card in slot 0 | toaster-0 |
| Quad-port Ethernet card in slot 1 |
toaster-1a toaster-1b toaster-1c toaster-1d |
A filer named toaster with an FDDI interface in slot 1 would have the host name toaster-f1.
