12 Configuring EFM OAM

This chapter contains a complete sample EFM OAM configuration. To see details on the

commands used in this example, or to see the outputs of the validation commands, refer

to the OAM Command Reference. To avoid repetition, some Common commands, like

configure terminal, have not been listed under the commands used sections.

12.1 Overview of EFM OAM configuration

The main functions of Ethernet to the First Mile - Operation Administration and

Maintenance (EFM-OAM) are link performance monitoring, fault detection, fault signaling

and loopback signaling. OAM information is conveyed in Slow Protocol frames called

OAM Protocol Data Units (OAMPDUs). OAMPDUs contain the appropriate control and

status information used to monitor, test and troubleshoot OAM-enabled links.

12.4 Configuration

Bridge1

DUT# configure terminal Enter the Configure mode.

DUT(config)#interface eth-0-9 Specify the interface (eth-0-9)to be

configured and enter the Interface mode

DUT(config-if)# ethernet oam enable Enable Ethernet OAM on eth-0-9

DUT(config-if)# ethernet oam mode active Configure Ethernet OAM mode as

active. (The default mode is passive.)

DUT(config-if)# ethernet oam timeout 10 Configure the link-timer as 10. Upon

expiry of the link timer, the discovery

process will restart.

DUT(config-if)# ethernet oam max-rate 1 Specify the maximum number of

OAMPDUS to be sent per .The range is

<1-10>

DUT(config-if)# end Exit the Interface mode.

Bridge2

DUT# configure terminal Enter the Configure mode.
