9.3.3 Enabling Dual-Ended Frame Loss Measurement on a VLL

Dual-ended frame loss measurement on a VLL is implemented on the MEPs at both ends of the
VLL to measure frame loss and check the connectivity of the VLL.
Context
Proactive OAM refers to OAM actions that are carried out continuously to permit proactive
reporting of faults or performance results. Dual-ended frame loss measurement on a VLL is
proactive OAM.

Dual-ended frame loss measurement is enabled on a VLL.
Frame loss measurement on a VLL is usually deployed on end-to-end MEPs. In Y.1731, frame
loss statistics are collected based on the transmit and receive counters carried by CCMs. Dual-
ended frame loss measurement on a VLL can be successfully performed only when the remote
MEP is in the Up state.

9.3.4 Checking the Configuration

After configuring dual-ended frame loss measurement on a VLL, you can view statistics about
frame loss at both ends of a link.
