What is MEP in CFM?

Maintenance association End Point (MEP) Points at the edge of the domain, define the boundary for the domain. A MEP sends and receives CFM frames through the relay function, drops all CFM frames of its level or lower that come from the wire side. Maintenance domain Intermediate Point (MIP)

What is up MEP and Down MEP?

Up MEP is created on UNI where as Down MEP is created on NNI. Up Mep packets will follow service path and be transmitted out. Down Mep packets will be transmitted directly since it is created on NNI.

What is meant by OAM in networking?

Operations, administration and management or operations, administration and maintenance (OA&M or OAM) are the processes, activities, tools, and standards involved with operating, administering, managing and maintaining any system. This commonly applies to telecommunication, computer networks, and computer hardware.

What is OAM switch?

Operations, Administration, and Maintenance (OAM) refers to the tools and utilities to install, monitor, and troubleshoot a network. OAM provides mechanisms to monitor link operation and health, and improve fault isolation.

What are OAM packets?

Ethernet OAM injects OAM packets into the normal stream of data packets at layer 2, and uses end points to process those packets to determine performance, with parameters such as improperly configured nodes, unidentified and out-of-place nodes, disconnected or failed nodes, frame loss, frame delay, end-to-end path …

Which CFM message type is used for an L2 ping?

MIPs are used for L2 ping and trace-route (which will be explained below). This provider similarly provides CFM within the boundaries of its network (shown as the pink 2). Metro Provider The Metro Provider (in green) uses the network of Access Network#1 and Access Network#2 to provide an overall metro Ethernet network.

What is maintenance domain?

1731 and MEF 35. The Metro Ethernet Forum has defined additional service OAM requirements, namely MEF 17. DEFINITIONS. Maintenance domain (MD): The portion of a network typically owned and operated by a single entity, over which connectivity faults can be managed.

What is Cisco cfm?

IEEE Connectivity Fault Management (CFM) is an end-to-end per-service Ethernet layer Operations, Administration, and Maintenance (OAM) protocol. This document describes the implementation of IEEE 802.1ag Standard-Compliant CFM (IEEE CFM) in Cisco IOS XE software.

What is OAM IP address?

Ethernet OAM comprises a set of manage- ment techniques for Carrier (or Metropolitan) Ethernet networks. Carrier Ethernet devices often have IP connectivity for management purposes, which might be used for IP OAM as an alternative management solution to Ethernet OAM.

What is Ethernet OAM Cisco?

Ethernet CFM is an end-to-end per VLAN Ethernet layer OAM protocol that includes proactive connectivity monitoring, fault verification, and fault isolation. Ethernet CFM, as specified by IEEE 802.1ag, is the standard for Layer 2 ping, Layer 2 traceroute, and end-to-end connectivity check of the Ethernet network.
