[Enterprise Switch] How to deploy Selective-QinQ environment. Follow

Extend from previous “How to config QinQ tunneling” chpter, we know that QinQ will insert a Service VID in front of preserved Customer VIDs. Selective QinQ could further configure the C-VID map to S-VID.

Support models

ECS4100 series, ECS4120 series, ECS4620 series, etc.

Application

For a company with branch site, they might use VLAN for different service (e.g. VOIP, File sharing). But the VID used in company might not be allowed to use in ISP Network. Selective QinQ could be used to forward different service VLAN traffic map to ISP provided VLAN with priority setting also reflect.

Topology:

Configure Selective QinQ setting at Switch-2 and Switch-3 :

Create S-VLANs:

Console(config)#vlan database

Console(config-vlan)#vlan 100,200,300 media ethernet state active

Console(config-vlan)#exit

Enable dot1q-service in global config

Console(config)#dot1q-tunnel system-tunnel-control

Configure a tagged member of VLANs 100, 200 and 300 using uplink mode

Console(config)#interface ethernet 1/25

Console(config-if)#switchport allowed vlan add 100,200,300 tagged

Console(config-if)#switchport dot1q-tunnel mode uplink

Console(config-if)#exit

Configures an untagged member of VLANs 100, 200 and 300 using access mode.

Console(config)#interface ethernet 1/1

Console(config-if)#switchport allowed vlan add 100,200,300 untagged

Console(config-if)#switchport dot1q-tunnel mode access

Console(config-if)#end

Configure the following selective QinQ mapping entries

Console#config

Console(config)#interface ethernet 1/1

Console(config-if)#switchport dot1q-tunnel service 100 match cvid 10

Console(config-if)#switchport dot1q-tunnel service 200 match cvid 20

Console(config-if)#switchport dot1q-tunnel service 300 match cvid 30

Console(config-if)#switchport dot1q-tunnel priority map

Check dot1q-tunnel setting

Console#show dot1q-tunnel

Console#

Configure VLAN setting at Switch-1 and Switch-4

Console(config)#vlan database

Console(config-vlan)#vlan 10,20,30 media ethernet state active

Console(config-vlan)#exit

Console(config)#interface ethernet 1/1
Console(config-if)#switchport mode access
Console(config-if)#switchport native vlan 10
Console(config-if)#switchport allowed vlan remove 1

Console(config)#exit

Console(config)#interface ethernet 1/2
Console(config-if)#switchport mode access
Console(config-if)#switchport native vlan 20
Console(config-if)#switchport allowed vlan remove 1

Console(config)#exit

Console(config)#interface ethernet 1/3
Console(config-if)#switchport mode access
Console(config-if)#switchport native vlan 30
Console(config-if)#switchport allowed vlan remove 1

Console(config)#interface ethernet 1/24-25
Console(config-if)#switchport mode trunk
Console(config-if)#switchport allowed vlan 10,20,30

Check the packet received on Uplink port will be specified according to QinQ mapping.

VLAN-10 (S-Vid 100 will be added refer to C-Vid 10, and the priority of C-Vid 5 will also be inherited on S-Vid)

VLAN-20 (S-Vid 200 will be added refer to C-Vid 20)

VLAN-30 (S-Vid 300 will be added refer to C-Vid 30)
