Validation
An OAM entity can put its remote entity into loopback mode using a loopback control OAMPDU. In
loopback mode, every frame received is transmitted back on that same port except for OAMPDUs. The
periodic exchange of OAMPDUs must continue during loopback state to maintain the OAM session. Once
we enable remote loopback in Bridge1, it sends out a loopback control OAMPDU with Enable remote
loopback command. When Bridge2 receives it, it changes its parser state to Loopback and MUX state to
discard and then sends out information OAMPDU with updated state information.
Validation Commands

Link Monitoring Event Configuration
We can configure high and low threshold for link-monitoring features. We can also configure an error
disable action if one of the high thresholds is exceeded.
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 link-monitor supported Enable the interface to support link
monitoring. This is the default.
DUT(config-if)# ethernet oam link-monitor on Start link monitoring.
