9.4.5 (Optional) Configuring Frame LM for a PW
This section describes how to configure single-ended or dual-ended frame loss measurement
(LM) to collect the reliability statistics of a pseudo wire (PW) built over a bidirectional label
switched path (LSP).
Context
Frame LM is a performance monitoring (PM) function provided by multiprotocol label switching
transport profile (MPLS-TP). Dual-ended frame LM is performed on the two maintenance entity
group end points (MEPs) of a PW. The measurement results are divided into near-end and far-
end frame loss:
l
Near-end frame loss: indicates the number and percentage of dropped frames that are sent
from a remote MEP (RMEP) to a MEP.
l
Far-end frame loss: indicates the number and percentage of dropped frames that are sent
from a MEP to an RMEP.
The NE80E/40E supports both single-ended and dual-ended frame LM functions. The
differences between them are listed in
