MEF Services Certification Program

The MEF Certification Program verifies compliance of Service Providers services to MEF technical specifications through a rigorous series of tests based on MEF approved Test Suites.

The program currently offers two certifications MEF 9 and MEF 14 covering the MEF Carrier Ethernet Services. The certification roadmap includes MEF 18 for CES over Ethernet and ENNI (Externel Network-to-Network Interface) that defines a compliant way for Service Providers to interconnect and offer services on a global footprint.


MEF Carrier Ethernet Services

MEF 9 and MEF 14 are service-oriented test specifications that define a series of Test Cases to verify the ability of a Carrier Ethernet network to deliver MEF-compliant Carrier Ethernet Services. Compliance is verified at the UNI (User Network Interface) which is the point where the provider interfaces with the subscriber to deliver the services.

MEF 9 Certification testing

MEF 9
Ethernet Services at the UNI: Defines a series of Test Cases to verify that Carrier Ethernet EPL, EVPL and ELAN services delivered by a Carrier Ethernet network at the UNI comply with the functional EVC (Ethernet Virtual Connection) and UNI (User Network Interface) Service Attributes and the Ethernet Services definitions defined in the MEF technical specifications MEF 10 and MEF 6.

The MEF Certification tests are performed in the field on a number of sites representing the coverage area of the services submitted for certification. Equipment deployed at the UNI must be MEF certified. This requirement does not apply to core equipment. The certifiable services are EPL (Ethernet Private Line), EVPL (Ethernet Virtual Private Line) and ELAN (Ethernet LAN).

Ethernet Private Line (EPL)

Overview
An EPL service is a fully tranpsarent service that offers point-to-point connectivity between two UNIs. 
Service Configuration
One point-to-point EVC associating two UNIs is configured across the same Carrier Ethernet network and all Service Frames are mapped to the EVC. Test probes are attached to both UNIs in the configured EVC.

Ethernet virtual Private Line (EVPL)

Overview
An EVPL service is a multiplexed service supporting more than one point-to-point connection on the same physical UNI to connect multiple remote sites
Service ConfigurationTwo Point-to-Point EVCs associating three UNIs are configured across the same Carrier Ethernet network and one CE-VLAN ID is mapped to each EVC. Test probes are attached to both UNIs in the configured EVCs.

Ethernet LAN (ELAN)

Overview
ELAN services offer multipoint-to-multipoint connectivity amongst multiple sites
Service ConfigurationOne Multipoint-to-Multipoint EVC associating three UNIs is configured across the same Carrier Ethernet network and one CE-VLAN ID or all Service Frames are mapped to the EVC. Test probes are attached to all UNIs in the configured EVC.

MEF Certification Documents

  • The MEF Certification tests are based on the Test Plans developped by Iometrix for each certification. The Test Plans together with other useful certification documents are available to MEF members for download from our website. MEF members should contact us at This e-mail address is being protected from spam bots, you need JavaScript enabled to view it to receive the download instructions.
  • All the MEF technical specifications are publicly available for download from the MEF website at MEF Technical Specifications.

Testing Process

  • Testing should be scheduled at least one month in advance and Iometrix does its utmost to accommodate service providers schedules.
  • Test Duration and Planning: Plan for at least 1 to 2 business days per service for MEF 9 certification and at least 3 to 4 business days per service for MEF 14 certification. If issues need to be resolved, tests may take longer depending on the time taken to troubleshoot.
  • Test Equipment: Iometrix supplies all test probes, software, scripts and related technical and logistical support.
  • Iometrix test engineers perform all tests and test procedures adhere strictly to the Test Plans as approved by the MEF.
