Configuring the EVPL Service Using UNI Traffic

  • PDF

Article summary

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

  1. 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
  1. 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
  1. 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
  1. Remove all ports from Management VLAN 1.
Your Product# configure terminal
Your Product(config)# no interface vlan 1
Your Product(config)#end
  1. 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
  1. 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
Switch default
