72 Chapter 6 Setting Network Preferences

Statically Configuring Ethernet Interfaces

You can configure your server to define an IPv4 address on an interface that does not

have a live link.

To define an IPv4 address on an interface that does not have a live link:

1 Edit the network preferences file located at /Library/Preferences/SystemConfiguration/

preferences.plist.

In the preferences.plist, navigate to the block that defines the relevant interface

(say, en1), look for the IPv4 configuration block, and add the IgnoreLinkStatus key.

Here is an example:

<dict>

<key>Addresses</key>

<array>

</array>

<key>ConfigMethod</key>

<string>Manual</string>

<key>IgnoreLinkStatus</key>

<true/>

<key>Router</key>

<key>SubnetMasks</key>

<array>

</array>

</dict>

2 Save the /Library/Preferences/SystemConfiguration/preferences.plist file.

3 To activate the modified preference, restart your system or use scselect to reselect the

current service (typically named Automatic, for example, scselect Automatic).

Creating, Deleting, and Viewing VLANs

A virtual local area network (VLAN) connects devices that may be on separate physical

LANs to perform and communicate as if they were on the same physical LAN. Use the

networksetup tool to configure and modify a VLAN.

To create a VLAN:

$ networksetup -createVLAN

name

parentdevice

tag

To delete a VLAN:

$ networksetup -deleteVLAN

name

parentdevice

tag

To list available VLANs:

$ networksetup -listVLANs

1 2 ... 67 68 69 70 71 72 73 74 75 76 77 ... 328 329
