Configuring Linktrace Protocol in CFM
The linktrace protocol is used for path discovery between a pair of maintenance
points. Linktrace messages are triggered by an administrator using the
command to verify the path between a pair of MEPs under the same maintenance
association. Linktrace messages can also be used to verify the path between an MEP
and an MIP under the same maintenance domain. The operation of IEEE 802.1ag
linktrace request and response messages is similar to the operation of Layer 3
traceroute

The E-LMI specification is available at the Metro Ethernet Forum. E-LMI procedures
and protocols are used for enabling automatic configuration of the customer edge
(CE) to support Metro Ethernet services. The E-LMI protocol also provides
user-to-network interface (UNI) and Ethernet virtual connection (EVC) status
information to the CE. The UNI and EVC information enables automatic configuration
of CE operation based on the Metro Ethernet configuration.
The E-LMI protocol operates between the CE device and the provider edge (PE) device.
It runs only on the PE-CE link and notifies the CE of connectivity status and
