Using cisco Catalyst Center ZTP for onboarding new devices

[Eric R. Jones]

Hello all, we have had our Catalyst Center up running since February. We have templates created to deploy config updates and now I want to start working with Zero Touch Provisioning to deploy out of the box devices or repurpose current devices in new locations. While at Cisco Live this year we were told that we had to use VLAN 1 in order to deploy ZTP due to the DHCP pool. I'm now finding videos where folks are using other Vlan's. This is what we require as VLAN 1 is not allowed to be on. My understanding is the basics are: DHCP Pool, Default Gateway address and use option 124 since we are using C9200 and C9300 access switches. 

If anyone knows of a current guide on deploying ZTP and has some history on their experience to impart that would be helpful.

Eric, this blog series is a great intro: https://blogs.cisco.com/developer/cisco-dna-center-plug-and-play-pnp-part-1

You can use a different vlan if the upstream switch is Cisco.  Use the "pnp startup-vlan <vlan>" command.

You'll use option 43 in your DHCP scope to inform the onboarding switch of the Cat Center IP address.

Don't forget about the "pnpa service reset" command (in 16.10 and later) to make it easy to wipe a device in a way that will trigger the pnp agent on bootup.

Wow that was fast. Thank you.

I'll be reading this blog today.

I'll update on my progress.

The only time you have to use Vlan 1 for ZTP is when using Lan Auto to onboard new devices.

I did some more searching and found this link, https://www.youtube.com/watch?v=T2bZvovhIzI. It's not the only video addressing the use of other vlan's besides 1 to deploy with but it's worth checking out. We are going to try this over the next week or two and see how it works.
