port link-type trunk
port trunk allow-pass vlan 20 30
#
interface GigabitEthernet0/0/2
port link-type access
port default vlan 20
#
interface GigabitEthernet0/0/3
port link-type access
port default vlan 30
#
SW2
interface GigabitEthernet0/0/1
port link-type dot1q-tunnel
port default vlan 10
#
interface GigabitEthernet0/0/2
port link-type trunk
port trunk allow-pass vlan 10
SW3
interface GigabitEthernet0/0/1
port link-type trunk
port trunk allow-pass vlan 10
#
interface GigabitEthernet0/0/2
port link-type dot1q-tunnel
port default vlan 10

PC1中的数据——>进入SW2的GE0/0/1的报文封装外层vlan 10,反之相同
SW2<——>SW3允许VLAN10的报文通过
