Use the show command again to display the status of pnp_startup_vlan.
When the downstream device is booted up, it sends notification to the connected upstream switch interface to unblock the pnp_startup_vlan for it to get the DHCP IP address and further establish communication with the PNP server or DNAC. The show command indicates
the status as "Unblocked".
The following syslogs on the upstream switch notify you about FWD and BLK of ports. There are no syslogs in the downstream
switch as PnP takes control of the console and no syslogs can be printed on the console.
REP-6-ZTPPORTFWD: Interface GigabitEthernet1/2 moved to forwarding on ZTP notification
REP-6-ZTPPORTBLK: Interface GigabitEthernet1/2 moved to blocking on ZTP notification
