By default, an interface uses the

Configuring the action a port takes after it receives
an Ethernet OAM event from the remote end
This feature enables a port to log events and automatically terminate the OAM connection and set
the link state to down.
To configure the action the port takes after it receives an Ethernet OAM event from the remote end:
Step Command Remarks
1. Enter system view.

N/A
2. Enter Layer 2/Layer 3
Ethernet port view.
interface
interface-type
interface-number
N/A
3. Configure the action the port
takes after it receives an
Ethernet OAM event from the
remote end.
oam remote-failure
{
connection-expired
|

|
dying-gasp
|
link-fault
}
action
error-link-down
By default, the port only logs the
Ethernet OAM event it receives
from the remote end.
Configuring Ethernet OAM remote loopback
CAUTION:
Use this function with caution, because enabling Ethernet OAM remote loopback impacts other
services.
When you enable Ethernet OAM remote loopback on a port, the port sends Loopback Control
OAMPDUs to a remote port, and the remote port enters the loopback state. The port then sends test
frames to the remote port. By observing how many of these test frames return, you can calculate the
packet loss ratio on the link and evaluate the link performance.
You can enable Ethernet OAM remote loopback on a specific port in user view, system view, or Layer
2 Ethernet port view. The configuration effects are the same.
Configuration guidelines
• Ethernet OAM remote loopback is available only after the Ethernet OAM connection is
established, and can be performed only by Ethernet OAM entities operating in active Ethernet
OAM mode.
• Remote loopback is available only on full-duplex links that support remote loopback at both
ends.
