Configure a Layer 2 Interface, Subinterface, and VLAN

Configure Layer 2 Interfaces with VLANs when you want Layer 2 switching and traffic separation among VLANs. You can optionally control non-IP protocols between security zones on a Layer 2 interface or between interfaces within a single zone on a Layer 2 VLAN.
  1. Configure a Layer 2 interface and subinterface and assign a VLAN ID.
    1. Select
      Network
      Interfaces
      Ethernet
      and select an interface. The
      Interface Name
      is fixed, such as ethernet1/1.
    2. For
      Interface Type
      , select
      Layer2
      .
    3. Select the
      Config
      tab.
    4. For
      VLAN
      , leave the setting
      None
      .
    5. Assign the interface to a
      Security Zone
      or create a
      New Zone
      .
    6. Click
      OK
      .
    7. With the Ethernet interface highlighted, click
      Add Subinterface
      .
    8. The
      Interface Name
      remains fixed. After the period, enter the subinterface number, in the range 1-9,999.
    9. Enter a VLAN
      Tag
      ID in the range 1-4,094.
    10. Assign the subinterface to a
      Security Zone
      .
    11. Click
      OK
      .
  2. Commit.
    Click
    Commit
    .
  3. (
    Optional
    ) Apply a Zone Protection profile with protocol protection to control non-IP protocol packets between Layer 2 zones (or between interfaces within a Layer 2 zone).
