This use case explains how you can configure an EVPL service taking UNI traffic on one VLAN and pushing a VLAN towards the NNI port and reverse path with a pop VLAN.

Configure the Customer VLAN Identification (C-VID) registration table for the UNI Port. This is for EVC mapping of the default customer VLAN ID to Service VLAN ID. Refer to Step 6.
The NNI port will egress out double tagged traffic.
Reverse path on NNI port will receive a double tagged packet and egress out only the single tagged packet on the UNI Port.

Note: To log in, enter your username (default is root) and password (default is admin123).

To configure an EVPL Service using UNI Traffic

Bring up the interfaces.

Your Product# configure terminal	
Your Product(config)# shutdown spanning-tree
Your Product(config)# interface xl-ethernet 0/1
Your Product(config-if)# no shutdown
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/2
Your Product(config-if)# no shutdown
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/3
Your Product(config-if)# no shutdown
Your Product(config-if)# end

Configure customerEdgePort and ProviderEdgePort.

Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/1
Your Product(config-if)# bridge port-type customerEdgePort double-tagged
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/2
Your Product(config-if)# bridge port-type providerNetworkPort
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/3
Your Product(config-if)# bridge port-type providerNetworkPort
Your Product(config-if)# end

Configure TPID.

Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/2
Your Product(config-if)# switchport egress ether-type 0x9100
Your Product(config-if)# switchport egress inner-ether-type 0x8100
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/3
Your Product(config-if)# switchport egress ether-type 0x9100
Your Product(config-if)# switchport egress inner-ether-type 0x8100
Your Product(config-if)# end

Remove all ports from Management VLAN 1.

Your Product# configure terminal
Your Product(config)# no interface vlan 1
Your Product(config)#end

Create S-VLAN and assign member port.

Your Product# configure terminal
Your Product(config)# vlan 100
Your Product(config-vlan)# ports xl-ethernet 0/1 xl-ethernet 0/2 xl-ethernet 0/3 untagged xl-ethernet 0/1
Your Product(config-vlan)# end
Your Product# configure terminal
Your Product(config)# vlan 200
Your Product(config-vlan)# ports xl-ethernet 0/1 xl-ethernet 0/2 xl-ethernet 0/3 untagged xl-ethernet 0/1
Your Product(config-vlan)# end
Your Product# configure terminal
Your Product(config)# vlan 300
Your Product(config-vlan)# ports xl-ethernet 0/1 xl-ethernet 0/2 xl-ethernet 0/3 untagged xl-ethernet 0/1
Your Product(config-vlan)# end
Your Product# configure terminal
Your Product(config)# vlan 400
Your Product(config-vlan)# ports xl-ethernet 0/1 xl-ethernet 0/2 xl-ethernet 0/3 untagged xl-ethernet 0/1
Your Product(config-vlan)# end
Your Product# configure terminal
Your Product(config)# vlan 500
Your Product(config-vlan)# ports xl-ethernet 0/1 xl-ethernet 0/2 xl-ethernet 0/3 untagged xl-ethernet 0/1
Your Product(config-vlan)# end

Configure EVPL (one to one) service mapping between S-VLAN & C-VLAN.

Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/1
Your Product(config-if)# switchport outer-customer-vlan 10 inner-customer-vlan 50 service-vlan 100
Your Product(config-if)# switchport outer-customer-vlan 20 inner-customer-vlan 60 service-vlan 200
Your Product(config-if)# switchport outer-customer-vlan 30 inner-customer-vlan 70 service-vlan 300
Your Product(config-if)# switchport outer-customer-vlan 40 inner-customer-vlan 80 service-vlan 400
Your Product(config-if)# switchport outer-customer-vlan 50 inner-customer-vlan 90 service-vlan 500
Your Product(config-if)# end
Your Product#

Enter show vlan port config port xl-ethernet 0/1 to check EtherType.

Your Product# show vlan port config port gigabitethernet 0/1
