DNAC connectivity

[pholos]

Hello everyone !

Can someone please explain to me why does DNAC need internet connectivity to perform pnp. 

I'm using DHCP so I don't see why it's needed.

I tried with and without and it only works when DNAC has connectivity.

Thanks

Hm... 
how do you connect your switches ?
do you have a local vlan for PnP ?
do you have DNS or DHCP option43 configured for PnP

or are the switches connecting to Cisco PnP connect?
in that case DNA needs access to Cisco PnP connect also.

Cisco Network Plug and Play Connect Capability Overview

DNA-C dosen't need internet connectivity for PnP by default, but it needs connection to the pnp cloud portal - you can limit the access to only the valid .cisco.com domains on the firewall. 

[DanielP211]

It needs access to the pnp cloud in case of usage of: Cisco Plug and Play Connect (cloud-based device discovery). 

Other options are:
● DHCP server, using option 43 (set the IP Address of the controller).
● DHCP server, using a DNS domain name (DNS lookup of pnphelper).
● USB key (bootstrap config file).

In this options the access to the pnp portal is not needed, but DNA-C still needs access to software.cisco.com for licensing and software...
