Important note regarding ZTP of SD-WAN Gateways

Although Aruba SD-WAN gateways have ZTP port on all ports except 0/0/1 as per https://help.central.arubanetworks.com/latest/documentation/online_help/content/sd_wan/provision_gateways/bring_up_gws.htm , most SD-WAN gateways are shipped with wireless controller firmware.  For wireless controller, the ZTP port in on the last copper port of the controller.   Hence it is important to note that we need to connect to the last copper port initially for the gateway to reach Activate & Central, followed by downloading SD-WAN firmware.  Once the download is completed and while rebooting, we can connect the cable to any other ZTP port as per the SD-WAN firmware specification.

 

Connect a console cable to the gateway console and watch the ZTP process:

 

Starting auto provisioning
Using port gigabitethernet 0/0/3 for auto provisioning
Initiated DHCP, awaiting DHCP response
Auto-provisioning is in progress. Choose one of the following options to override or debug...
'enable-debug' : Enable auto-provisioning debug logs
'disable-debug' : Disable auto-provisioning debug logs
'mini-setup' : Stop auto-provisioning and start mini setup dialog for branch role
'full-setup' : Stop auto-provisioning and start full setup dialog for any role
Enter Option (partial string is acceptable): enable-debug

Note that as of the date of this article is written, the ZTP process works only on controller installed 6.5.1.4 & above but not 8.x.x.x wireless firmware.   For controller not installed with 6.5.1.4 & above or installed with 8.x.x.x wireless firmware, it's probably quicker to install SD-WAN firmware directly (and if required, factory default it) and then let ZTP process to take over.
