Selective QinQ application
1. Ethernet1/1 of SwitchA provides public network access for PC users and Ethernet 1/2 of
SwitchA provides public network access for IP phone users. PC users belong to VLAN 100
through VLAN 200, and IP phone users belong to VLAN 201 through VLAN 300. Ethernet 1/9
of SwitchA is connected to the public network.
2. Ethernet1/1 and Ethernet1/2 of SwitchB provide network access for PC users belonging to
VLAN 100 through VLAN 200 and IP phone users belonging to VLAN 201 through VLAN 300
respectively. Ethernet 1/9 is connected to the public network.
3. The public network permits packets of VLAN 1000 and VLAN 2000 to pass.
4. Enable the selective QinQ on Ethernet1/1 and Ethernet1/2 ports of Switch A and Switch B
respectively. Packets of VLAN 100 through VLAN 200 are tagged with the tag of VLAN 1000
as the outer VLAN tag on Ethernet1/1, and packets of VLAN 201 through VLAN 300 are
tagged with the tag of VLAN 2000 as the outer VLAN tag.
Steps of configuration:
# Create VLAN 1000 and VLAN 2000 on SwitchA.
switch(config)#vlan 1000;2000
# Configure Ethernet1/1 as a hybrid port and configure it to remove VLAN tags when
forwarding packets of VLAN 1000.
switch(config-if-ethernet1/1)#switchport hybrid allowed vlan 1000 untag
# Configure the mapping rules for selective QinQ on Ehernet1/1 to insert VLAN 1000 tag as
the outer VLAN tag in packets with the tags of VLAN 100 through VLAN 200.
switch(config-if-ethernet1/1)#dot1q-tunnel selective s-vlan 1000 c-vlan 100-200
# Enable selective QinQ on Ethernet1/1.
switch(config-if-ethernet1/1)#dot1q-tunnel selective enable
# Configure Ethernet 1/2 as a hybrid port and configure it to remove VLAN tags when
forwarding packets of VLAN 2000.
switch(config-if-ethernet1/2)#switchport mode hybrid
switch(config-if-ethernet1/2)#switchport hybrid allowed vlan 2000 untag
# Configure mapping rules for selective QinQ on Ehernet1/2 to insert VLAN 2000 tag as the
outer VLAN tag in packets with the tags of VLAN 201 through VLAN 300.
switch(config-if-ethernet1/2)#dot1q-tunnel selective s-vlan 2000 c-vlan 201-300
# Enable selective QinQ on Ethernet 1/2.
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
