Y.1731 Ethernet OAM Ethernet Operation, Administration and Management
Y.1731 Ethernet OAM
Y.1731 Ethernet OAM standard provides superset of functionalities provided in CFM and
additional performance monitoring functionality. Y.1731 performance monitoring functions
enable continuous control of Service Level Agreement objectives.
The connectivity fault management functionality of the end-to-end network is divided into
hierarchical management spaces referred to as Maintenance Entity Groups (MEGs) There
are three Maintenance Domain levels: Operator, Service Provider and Customer. The
hierarchical relationship is based on numerically assigned values from 0 to 7 that correspond
to the levels.
MEGs are demarcated by Maintenance End Points (MEPs) belonging to a common service or
provider. These objects generate and manage end-to-end sessions and it is required to
configure them in order to provide connectivity control, fault isolation and SLA monitoring.
In addition (and optionally) Maintenance Intermediate Points (MIPs) can be configured, in
order to provide additional information for fault isolation.
To configure Y.1731
1. Enable the Y.1731 OAM option on the ML unit.
2. Configure the MEGs.
3. Allocate MEPs per each MEG which has end-points on the ML unit.
4. Allocate MIPs if no MEP of this MEG planned on the ML unit.
5. Allocate Remote MEPs (RMEPs).
