Interface Labels

Configuration > Overlays & Security > Interface Labels

To make it easier to identify connections, you can create descriptive interface labels for each link type in your environment. Use labels to match and route traffic into overlays. The label type specifies “which side” of the network the interface is on. LAN labels identify LAN-side data (subnets), and WAN labels identify the WAN service, such as MPLS, Internet, or LTE. If you edit a label, tunnels that reference that labeled interface are renamed accordingly.

• LAN labels can be selected for a traffic access policy in a Business Intent Overlay (BIO), which in turn is applied to an appliance with those LAN labels. All traffic matching those interfaces is automatically processed by that BIO. If you use an ACL for a traffic access policy, the LAN label is ignored for that BIO.

• WAN labels are used by Orchestrator and BIOs to determine which interfaces on different appliances should be connected by tunnels built by Orchestrator. Orchestrator automatically pushes interface labels to appliances it manages.

Manage Labels

Use the Interface Labels dialog box to manage labels in Orchestrator, available under Configuration > Overlays & Security > Interface Labels.

From this dialog box, you can create, edit, or delete labels.

Create a Label

1. Click New Label.

   The Interface Label Configuration dialog box opens.

   

2. Select wan or lan for the label type.

3. Enter a descriptive name in the Label Name field.

   NOTE: For WAN labels, if you want to allow Orchestrator to build tunnels using this label in any topology, leave the Topology selection set to any. If you want to override BIO settings and exclude this label in Full Mesh overlays, set Topology to Hub & Spoke.

4. Click Done to save your changes and close the dialog box. Otherwise, click Close to cancel and return to the list of interface labels.

Edit a Label

1. In the Interface Labels dialog box, click the edit icon to the right of an existing label.

2. Select wan or lan for the label type—you cannot change the label type if the label is currently in use.

3. If you want to change the label name, modify it in the Label Name field.

   NOTE: For WAN labels, if you want to allow Orchestrator to build tunnels using this label in any topology, leave the Topology selection set to any. If you want to override BIO settings and exclude this label in Full Mesh overlays, set Topology to Hub & Spoke.

4. Click Done to save your changes and close the dialog box. Otherwise, click Close to cancel and return to the list of interface labels.

Delete a Label

1. In the Interface Labels dialog box, click the X icon to the left of a label you want to delete.

   NOTE: Labels used in overlays cannot be deleted.

   The label is deleted from the list but can be restored by closing the dialog box without saving.

2. To save your changes and permanently delete the label, click Save.

   WARNING: When deleting a label, a confirmation message warns you that deleted interface labels will be removed from all policies, interfaces, and deployment profiles that are currently using the label.

3. Click Save to confirm the removal. Otherwise, click Cancel to return to the Interface Labels dialog box.
