If you change the names of two or more external VLAN interfaces at the same time, some interfaces might not appear in the Link Monitor tab, Monitored Interface list. You also might not be able to edit SD-WAN actions that include the interfaces.
To avoid this issue, we recommend that you change only one VLAN interface name at a time in the Network Configuration dialog box, VLAN tab. Click OK to confirm the change and return to the main Policy Manager dialog box before you change another VLAN interface name.If you already have this issue, connect to the Firebox Web UI, open the SD-WAN action, update the settings as needed, and click Save.
