Configuring Ethernet Oam Remote Loopback; Configuration Guidelines; Enabling Ethernet Oam Remote Loopback On A Specific Port - HP 5130 EI Series Configuration Manual

Step
3. Configure the action the port
takes after it receives an
Ethernet OAM event 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.
•
• Ethernet OAM remote loopback must be supported by both the remote port and the sending port.
Enabling Ethernet OAM remote loopback interrupts data communications. After Ethernet OAM
•
remote loopback is disabled, all the ports involved will shut down and then come up. Ethernet OAM
remote loopback can be disabled by any of the following events: disabling Ethernet OAM,
disabling Ethernet OAM remote loopback, and Ethernet OAM connection timing out.
Enabling internal loopback test on a port in remote loopback test can terminate the remote
•
loopback test. For more information about loopback test, see Layer 2—LAN Switching

Enabling Ethernet OAM remote loopback on a specific port

Step
1. (Optional.) Enter system view.
2. Enable Ethernet OAM remote
loopback on a specific port.
Command

Remarks
By default, the port only logs the
Ethernet OAM event it receives
from the remote end.
Remarks
N/A
By default, Ethernet OAM remote
loopback is disabled.
This command can be executed in
user view or system view.
