According to the topology and configuration of the interconnected interface of switches shown in the figure, the data frame tagged with VLAN 10 can be forwarded correctly between two switches.
[LSW1]interface GigabitEthernet0/0/1
[LSW1-interface GigabitEthernet0/0/1]port link-type trunk [LSW1-interface GigabitEthernet0/0/1]port trunk pvid vlan 20
[LSW1-interface GigabitEthernet0/0/1]port truck allow-pass vlan 10

[LSW2]interface GigabitEthernet0/0/1
[LSW2-interface GigabitEthernet0/0/1]port link-type trunk [LSW2-interface GigabitEthernet0/0/1]port trunk pvid vlan 10
[LSW2-interface GigabitEthernet0/0/1]port truck allow-pass vlan 10
