The possible reason is that some ports are in access mode though
configured for trunk mode? Why could that be?

!
interface GigabitEthernet0/1
 switchport trunk encapsulation dot1q
 switchport mode trunk

#sh int GigabitEthernet0/1 switchport

Switchport: Enabled
Administrative Mode: trunk
Operational Mode: static access
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: native
Negotiation of Trunking: On
Access Mode VLAN: 1 (default)

Why is the port in static access mode while it is configured as
"switchport mode trunk" and has the administrative mode "trunk"?
