Change Assigned ASN (Datacenter)

Assign or change individual ASNs.

Normally, ASNs are pulled automatically from resource pools, but there may be times when you need to assign a specific ASN. In these cases, you can select the device and assign or change the ASN from the Properties tab.

To assign or change a specific ASN using the GUi:

  1. From the blueprint, navigate to Staged > Physical > Topology and select the device to update. (Alternatively, you can navigate to Staged > Physical > Nodes and select the device from the Nodes table.)
    Network management interface with staged configuration tab selected. Physical topology view shows spine-leaf switches and connected servers. Uncommitted changes layer active.
    The Selection panel on the right becomes active and populates with information about the selection.
  2. Click the Properties tab in the Selection panel, then click the Edit button for the ASN field.

    The ASN field becomes available to change.
  3. Enter the new ASN value.
  4. Click the Save button.
