switch(config-if-ethernet1/2)#dot1q-tunnel selective enable
# Configure uplink port Ethernet 1/9 as a hybrid port and configure
it to save VLAN tags when forwarding packets of VLAN 1000 and VLAN
2000.
switch(config-if-ethernet1/2)#interface ethernet 1/9
switch(config-if-ethernet1/9)#switchport mode hybrid
switch(config-if-ethernet1/9)#switchport hybrid allowed vlan 1000;2000 tag
After the above configuration, packets of VLAN 100 through VLAN 200 from Ethernet1/1 are
automatically tagged with the tag of VLAN 1000 as the outer VLAN tag, and packets of VLAN
201 through VLAN 300 from Ethernet1/2 are automatically tagged with the tag of VLAN 2000
as the outer VLAN tag on SwitchA.
The configuration on Switch B is similar to that on Switch A, the configuration is as follows:
switch(config)#vlan 1000;2000
switch(config)#interface ethernet 1/1
switch(config-if-ethernet1/1)#switchport mode hybrid
switch(config-if-ethernet1/1)#switchport hybrid allowed vlan 1000

switch(config-if-ethernet1/1)#dot1q-tunnel selective s-vlan 1000 c-
vlan 100-200
switch(config-if-ethernet1/1)#dot1q-tunnel selective enable
switch(config-if-ethernet1/1)#interface ethernet 1/2
switch(config-if-ethernet1/2)#switchport hybrid allowed vlan 2000
untag
switch(config-if-ethernet1/2)#dot1q-tunnel selective s-vlan 2000 c-
vlan 201-300
switch(config-if-ethernet1/2)#dot1q-tunnel selective enable
switch(config-if-ethernet1/9)#switchport mode hybrid
switch(config-if-ethernet1/9)#switchport
hybrid allowed vlan
1000;2000 tag
18.3.4 Selective QinQ Troubleshooting

Selective QinQ and dot1q-tunnel functions should not be configured synchronously for
a port.
18.4 VLAN-translation Configuration
18.4.1 Introduction to VLAN-translation
VLAN translation, as one can tell from the name, which translates the original VLAN ID to new
