12.5 Remote Loopback Configuration
We must enable Ethernet OAM remote loopback on an interface for the local OAM client
to initiate OAM remote loopback operations. It is disabled by default.
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 remote loopback supported Enable Ethernet remote loopback on
eth-0-9.
DUT(config-if)# ethernet oam remote loopback start Turn on remote-loopback on eth-0-9
DUT(config-if)# ethernet oam remote loopback stop Turn off remote-loopback on eth-0-9
DUT(config-if)# end Exit the Interface mode.
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.
