Double tag service
Add the designated outer VLAN tag (ovlan) according to the designated inner VLAN (in-vlan).
Data uplink：Classify data traffic entering from customer port and add the outer tag ovlan to packets with in-vlan.
Data downlink: When packets with double tag flow to the uplink port, forward them according to L2 forwarding principle; strip the outer tag from them when the packets are forwarded on the customer port.
[related command]ZXR10(config)#vlan qinq session 1 customer gei_3/1 uplink gei_2/1 in-vlan ovlan 999
Double tag ＋ designated priority
According to the designated inner vlan, add the designated outer vlan tag, and add the designated priority; schedule and forward the data traffic according to the designated priority. Data uplink: Classify data traffic entering from customer port and add the outer tag ovlan to packets with in-vlan, and add the designated 802.1P priority. Data downlink: When packets with double tag flow to the uplink port, forward them according to L2 forwarding principle; strip the outer tag from them when the packets are forwarded on the customer port.
[related command]ZXR10(config)#vlan qinq sessin 2 customer fei_5/1 uplink gei_1/1 in-vlan ovlan 997 priority 5
Double tag + mapping priority
According to the designated inner VLAN, add the designated outer VLAN tag, and map the inner VLAN priority to the outer VLAN tag priority. If the inner tag priority is not considered, it does not need to map. Data uplink: Classify data traffic entering from customer port and add the outer tag ovlan to packets with in-vlan, and map the inner VLAN priority of each packet to the outer VLAN.Data downlink: When packets with double tag flow to the uplink port, forward them according to L2 forwarding principle; strip the outer tag from them when the packets are forwarded on the customer port.

VLAN transparent transmission service
For the designated VLAN transparent transmission, do not add the outer tag. Data uplink: Classify data traffic entering from customer port and add the helper_vlan outer tag to packets with in-vlan, with the aim to aggregate multiple transparent transmission vlans, encapsulate channel with helper_vlan, strip helper_vlan on the outgoing interface and transparently transmit the packets. Data downlink: Transparently transmit VLAN data traffic to the uplink port, and according to L2 forwarding principle, forward the traffic from the customer port in original shape.
[related command]ZXR10(config)#vlan qinq session 4 customer fei_2/1 uplink gei_2/2n-vlan untag helper-vlan 1
Untag packet service
This type of service is rare. For packets without tag entering the customer port, add the corresponding VLAN tag on the outgoing interface. Data uplink: Classify data traffic entering from customer port, and for untagged packets, if they are configured with the egress tag, add the designated VLAN tag instead of adding the outer tag according to PVID of the port.
Data downlink: the downlink data packets are forwarded normally.

Configuration of Switch A
ZXR10_A(config)# vlan 10
ZXR10_A(config)# interface gei_3/1
ZXR10_A(config-if)# switchport qinq customer
ZXR10_A(config-if)# switchport access vlan 10
ZXR10_A(config)# interface gei_3/24
ZXR10_A(config-if)# switchport qinq uplink
ZXR10_A(config-if)# switchport mode trunk
ZXR10_A(config-if)# switchport trunk vlan 10
Configuration of Switch B
ZXR10_B(config)# vlan 10
ZXR10_B(config)# interface gei_7/1
ZXR10_B(config-if)# switchport qinq customer
ZXR10_B(config-if)# switchport access vlan 10
ZXR10_B(config)# interface gei_7/24
ZXR10_B(config-if)# switchport qinq uplink
ZXR10_B(config-if)# switchport mode trunk

8. SVLAN Configuration Configure SVLAN rule for packet with tag
ZXR10(config)# vlan qinq session-no <session-id> customer-port <port-id> uplink-port <port-id>{{in-vlan <vlan-id>{{ovlan <vlan-id>}}}| default-vlan-forwarding }
default-vlan-forwarding :Transparent transmission function
When the customer port is on the old line card (8270), and the uplink port is the smartgroup, this function will become invalid and the use is restricted; and the other case is that, when using native vlan to add the outer tag, the two can not be used simultaneously.
Configure SVLAN rule for packet without tag
ZXR10(config)# vlan qinq session-no <session-id> customer-port <port-id> uplink-port <port-id>{untag ovlan <vlan-id>[undirect]}
Display SVLAN configuration information
ZXR10(config)# show vlan qinq [session <session-id>] 8

10. SVLAN Configuration Example –Requirements
For datagram of VLAN from 8905 gei_1/1 (assume the frames of this VLAN range to be PPPOE dial-in user), add outer tag vlan997 on 8905 and uplink to BRAS via gei_1/4.
For datagram of VLAN from 8905 gei_1/2 (assume the frames of this VLAN range to be PPPOE dial-in user), add outer tag vlan998 on 8905 and uplink to BRAS via gei_1/4.
For datagram of VLAN from 8905 gei_1/1-2 (assume the frames of this VLAN range to be private network user), transparently transmit these VLANs via 8905 and uplink to T600 via gei_1/3.
For the untagged frames received on 8905 gei_1/1-2, add a tag 1100 on and uplink to T600 via gei_1/3;
Configure vlan3000 as management VLAN, used to manage 8905 and 2826E via T600, management VLAN should contain no outer tags.
