Set up a VLAN

To set up and manage VLANs, you use the VLAN area of the Network pane of System Preferences.

Be sure that ports used by non-VLAN devices (non-802.1q-compliant) are configured to transmit untagged frames. If a noncompliant Ethernet device receives a tagged frame, it cannot understand the VLAN tag and drops the frame.

Note:  The VLAN area of the Network pane is visible only if your hardware supports this feature.

  1. Log in to your server as an administrator.

  2. Open the Network pane of System Preferences.

  3. Click the Action pop-up menu gear, then choose Manage Virtual Interfaces.

  4. Click Add add, then select New VLAN.

  5. In the VLAN Name field, enter a name for the VLAN.

  6. In the Tag field, enter a tag (a number between 1 and 4094).

    This VLAN tag designates the VLAN ID (VID). Each logical network has a unique VID. Interfaces configured with the same VID are on the same virtual network.

  7. Select the Interface.

  8. Click Create.

  9. Click Done.
