Create BIG-IP objects for Layer 2 transparency

To configure the BIG-IP system as an inline device operating in Layer 2 transparency mode, you first need to create a virtual wire configuration object. Creating a virtual wire object causes the BIG-IP system to automatically perform these actions:
  • Create trunks for accepting all VLAN traffic, with Link Aggregation Protocol (LACP) enabled.
  • Set the trunk members (interfaces) to virtual wire mode.
  • Create two VLANs with tag 4096 that allow all Layer 2 ingress traffic.
  • Create a VLAN group to logically connect the VLANs.
  1. On the Main tab, click
    Virtual Wire
    This object appears on certain BIG-IP platforms only.
    The Virtual Wire screen opens.
  2. Click
  3. In the
    field, type a name for the virtual wire object.
  4. On the right side of the screen, click the double-arrow symbol to expand the Shared Objects panel.
  5. Click within the Trunks heading area.
    This displays a list of existing trunks, and displays the
    symbol for creating a trunk.
  6. Click the
  7. In the
    field, type a name for the trunk, such as
  8. In the
    list, select the check boxes for the interfaces that you want to include in the trunk.
  9. From the
    list, select
    This enables the Link Aggregation Control Protocol (LACP) to monitor link availability within the trunk.
  10. Click
    If you do not see the
    button, try using a different browser.
    This creates the trunk that you can specify as an interface when you complete the creation of the virtual wire object.
  11. Repeat steps 6 through 10 to create a second trunk.
  12. In the Member 1 column, from the
    list, select a trunk name, such as
  13. In the Member 2 column, from the
    list, select another trunk name, such as
  14. In the VLAN Traffic Management Configuration column, for the
    Define VLANs
    list, use the default value of
  15. Click

After you perform this task, the BIG-IP system contains a virtual wire object, two trunks, two VLANs, and a VLAN group.
