Remote Loopback
An active-mode device can place a passive peer into loopback mode by sending a Loopback Control
OAMPDU. When in loopback mode:
• the remote peer returns unaltered all non-OAMPDU frames sent by the local peer, and
• all outbound data frames are discarded.
Task Command Syntax Command Mode
Block or disable an interface when a
particular critical link event occurs.
ethernet oam remote-failure {critical-event |
dying-gasp | link-fault} action {error-block-interface |
error-disable-interface}
Default: Disabled
INTERFACE
Note: Control traffic egresses from loopback initiator and from interface in loopback mode. You must
explicitly disable L2/L3 protocols to stop control traffic.
Task Command Syntax Command Mode
Enable support for the OAM loopback
capability on an interface so that it can
exchange information with a remote peer.
ethernet oam remote-loopback supported
Default: Enabled
INTERFACE
Configure the maximum amount of time
the local peer waits for a frame to be
returned before considering the remote
peer to be non-operational.

Start or stop loopback operation on a local
interface with a remote peer.
