How to force untagged packages to go in the Cicso lab?

Question

Cisco

I want to make pings go between PC8 and PC7. They are not included in any VLAN, i.e. by default they are in VLAN1. The rest of the infrastructure works as it should. For some reason STP blocks ports on 3560 when I try to ping PC8 and PC7 between themselves.
I tried to configure addresses in the same subnet on vlan 1 of all switches, I tried the same without addresses on vlan 1.
I thought that vlan 1 would be routed without additional gestures, it turns out not. Those. to summarize the question, why does vlan 1 (which is everywhere by default) not pass through 3560 if I included it in the necessary trunks?

Answer 1

3560 on port fa0/1 you do not have vlan 1 allowed (switchport trunk allowed vlan 2-3).
