MEF 10.2 Regulator on EPL Service with One Class of Service

  • PDF

Article summary

This use case explains how you can configure an MEF 10.2 regulator on Ethernet Private Line (EPL) service with one Class of Service (CoS).

  • EPL services on the UNI Port will be classified based on L2 ACL with UNI Port; the classified traffic will be assigned a specific Traffic Class or Queue based on the Queue Mapping configuration.


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

To configure an MEF 10.2 regulator on EPL service with one CoS

  1. Bring up the physical interface.
Your Product# configure terminal
Your Product(config)# shutdown spanning-tree
Your Product(config)# end
Your Product# configure terminal
Your Product(config)# interface gigabitethernet 0/1
Your Product(config-if)# no shutdown
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface gigabitethernet 0/2
Your Product(config-if)# no shutdown
Your Product(config-if)# end
  1. Configure customerEdgePort and ProviderEdgePort.
Your Product# configure terminal
Your Product(config)# interface gigabitethernet 0/1
Your Product(config-if)# bridge port-type customerEdgePort
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface gigabitethernet 0/2
Your Product(config-if)# bridge port-type providerNetworkPort
Your Product(config-if)# end
  1. Configure S-VLAN and assign member ports.
Your Product(config)# vlan 100
Your Product(config-vlan)# ports gigabitethernet 0/1 gigabitethernet 0/2 untagged gigabitethernet 0/1
Your Product(config-vlan)# end
Your Product# configure terminal
Your Product(config)# vlan 200
Your Product(config-vlan)# ports gigabitethernet 0/1 gigabitethernet 0/2 untagged gigabitethernet 0/1
Your Product(config-vlan)# end
  1. Configure EPL service mapping between C-VLAN and S-VLAN.
Your Product# configure terminal
Your Product(config)# interface gigabitethernet 0/1
Your Product(config-if)# switchport customer-vlan 10 service-vlan 200
Your Product(config-if)# no shutdown
Your Product(config-if)# end
  1. Configure Access list for traffic classification.
Your Product# configure terminal
Your Product(config)# mac access-list extended 1003
Your Product(config-ext-macl)# permit any any vlan 10 priority 50 cvlan-priority 6 double-tag
Your Product(config-ext-macl)# end
  1. Apply the Access list to physical interface.
Your Product# configure terminal
Your Product(config)# interface gigabitethernet 0/1
Your Product(config-if)# mac access-group 1003 in
Your Product(config-if)# end
  1. Configure QoS Class.
Your Product# configure terminal
Your Product(config)# class 30
Your Product(config-cls-map)# match access-group mac-access-list 1003
Your Product(config-cls-map)# set class 30
Your Product(config-cls-map)# end
  1. Assign the QoS CLASS to virtual Queue.
Your Product# configure terminal
Your Product(config)# queue-map CLASS 30 queue-id 3
Your Product(config)# end
  1. Check Class-map and Queue-map status by entering command show class-map 30 and show queue-map.
Your Product#show class-map
