Network interface configuration
Types of network interface information

Editing network interface information

 This window enables you to view and modify the configuration information about network interfaces on the filer.

Types of network interface information

The following list describes the network interface information displayed on the first line for each interface:

Interface
The name the filer automatically assigns to the interfaces installed in the filer. The filer uses the following naming convention:
  • Ethernet interface names start with the letter e followed by the slot number (for example, e0) and the port number if the network card has more than one port (for example, a quad-port Ethernet card has four interfaces named e1a, e1b, e1c, and e1d).
  • FDDI interface names start with the letter f followed by the slot number (for example, f1 and f2).
  • ATM interface names start with the letter a followed by the slot number (for example, a5).
  • The loopback address is shown as lo.
  • The virtual host name is shown as vh.
Flags
The state of the interface.
MTU
The maximum transmission unit (MTU). By default, the MTU is 4,352 on an FDDI interface, 1,500 on an Ethernet interface, and 9,188 on an ATM interface.

The following list describes the network interface information displayed on the second line for each interface except the loopback interface and the virtual host:

MAC Address
The 12-digit hexadecimal physical address of the interface.
Media
The physical media connecting the filer to the network.

Editing network interface information

The following list describes the network interface information displayed on the third line for each interface:

  • the IP address of the interface.
  • the subnet mask for the interface
  • the broadcast address for the interface

The following list describes how to use the buttons in this window to modify the network interface information:

Reload
Reloads the current network interface configuration information from the filer.
Add Alias
Specifies an IP address for the following types of interfaces:
  • physical interface: Use this button to specify an additional IP address for the interface. This is useful when you need to change the IP address of an interface and you want the interface to continue receiving packets destined for the old address.
  • virtual host: Use this button to specify an IP address for a virtual host.
Delete Alias
Removes the alias IP address specified with the Add Alias button.
Modify
Click the appropriate interface in the display and click Modify to change the configuration of the selected interface.
