+### Debug the PnP process on the network device
+
+After the network devis is connected to the PnP server you can access the decvice on the console. This will not stop the PnP process any more.
+If the device conncted to the PnP server you sould find the PnP profile in the config i.e.
+```
+pnp profile pnp-zero-touch
+ transport http ipv4 192.168.10.133 port 8080
+end
+```
+By removing and re-creationg the PnP profile you will restart the PnP process for the device. This way you can also connect a device by hand to the PnP server.
+```
+conf t
+no pnp profile pnp-zero-touch
+pnp profile pnp-zero-touch
+ transport http ipv4 192.168.10.133 port 8080
+end
+```
+Here are some usefull commnads to debug the PnP process on the device
+```
+debug pnp service copy
