CHAPTER 12
Configuring Ethernet Local Management
Interface at a Provider Edge
The advent of Ethernet as a metropolitan-area network (MAN) and WAN technology imposes a new set of
Operation, Administration, and Management (OAM) requirements on Ethernet's traditional operations, which
had centered on enterprise networks only. The expansion of Ethernet technology into the domain of service
providers, where networks are substantially larger and more complex than enterprise networks and the
user-base is wider, makes operational management of link uptime crucial. More importantly, the timeliness
in isolating and responding to a failure becomes mandatory for normal day-to-day operations, and OAM
translates directly to the competitiveness of the service provider.
The “Configuring Ethernet Local Management Interface at a Provide Edge” module provides general
information about configuring an Ethernet Local Management Interface (LMI), an OAM protocol, on a
provider edge (PE) device.

Prerequisites for Configuring Ethernet Local Management
Interface at a Provider Edge
•
Ethernet Operation, Administration, and Management (OAM) must be operational in the network.
•
For Ethernet OAM to operate, the provider edge (PE) side of a connection must be running Ethernet
Connectivity Fault Management (CFM) and Ethernet Local Management Interface (LMI).
•
All VLANs used on a PE device to connect to a customer edge (CE) device must also be created on that
CE device.
