Edge uplinks go out through VLAN logical switches.

When you are creating a VLAN logical switch, it is important to have in mind a particular topology that you are building. For example, the following simple topology shows a single VLAN logical switch inside of a VLAN transport zone. The VLAN logical switch has VLAN ID 100. This matches the VLAN ID on the TOR port connected to the hypervisor host port used for the Edge's VLAN uplink.

  • To create a VLAN logical switch, you must first create a VLAN transport zone.

  • An NSX-T Data Center vSwitch must be added to the NSX Edge. To confirm on an Edge, run the get host-switches command. For example:
    nsx-edge1> get host-switches
    Host Switch         : c0a78378-1c20-432a-9e23-ddb34f1c80c9
    Switch Name         : hs1
    Transport Zone      : c46dcd72-808a-423d-b4cc-8752c33f6b2c
    Transport Zone      : 73def985-d122-4b7b-ab6a-a58176dfc32d
    Physical Port       : fp-eth0
    Uplink Name         : uplink-1
    Transport VLAN      : 4096
    Default Gateway     :
    Subnet Mask         :
    Local VTEP Device   : fp-eth0
    Local VTEP IP       :
  • Verify that fabric nodes are successfully connected to the NSX-T Data Center management plane agent (MPA) and the NSX-T Data Center local control plane (LCP).

    In the GET https://<nsx-mgr>/api/v1/transport-nodes/<transport-node-id>/state API call, the state must be success. See the NSX-T Data Center Installation Guide.

  • Verify that Manager mode is selected in the NSX Manager user interface. See NSX Manager. If you do not see the Policy and Manager mode buttons, see Configure the User Interface Settings.


  1. From a browser, log in to an NSX Manager at https://<nsx-mgr>.
  2. Select Networking > Logical Switches > Switches > Add.
  3. Type a name for the logical switch.
  4. Select a transport zone for the logical switch.
  5. Select an uplink teaming policy.
  6. For admin status, select Up or Down.
  7. Type a VLAN ID.
    Enter 0 in the VLAN field if there is no VLAN ID for the uplink to the physical TOR.
  8. (Optional) Click the Switching Profiles tab and select switching profiles.


Note: If you have two VLAN logical switches that have the same VLAN ID, they cannot be connected to the same Edge N-VDS (previously known as hostswitch). If you have a VLAN logical switch and an overlay logical switch, and the VLAN ID of the VLAN logical switch is the same as the transport VLAN ID of the overlay logical switch, they also cannot be connected to the same Edge N-VDS.

What to do next

Add a logical router.
