26 LINK OAM Commands
Ethernet in the First Mile (EFM), also known as LINK OAM, is a collection of protocols specified in
IEEE 802.3ah, defining Ethernet in the access networks that connects subscribers to their immediate
service provider. EFM, EFM-OAM and LINKOAM refers to IEEE 802.3ah standard.
LINK OAM (operation, administration, and maintenance) is a tool which monitors Layer-2 link status on
the network by sending OAM protocol data units (OAMPDUs) between the network devices. OAMPDUs
contain control and status information used to monitor, test and troubleshoot OAM-enabled links. By
enabling LINK OAM on switch ports, network administators can monitor the link-related issues on the
first mile. LINK OAM provides network administrators the ability to monitor link performance, remote
fault detection and remote loopback control.
Note.
EFM (LINK OAM) does not include functions such as station management, bandwidth allocation or
provisioning functions.
MIB information for the EFM (LINK OAM) commands is as
