To do…
Use the command…
Remarks
Enable Ethernet OAM on the
current port
oam enable
Required
Ethernet OAM is disabled by
default.
NOTE:
To change the Ethernet OAM mode on an Ethernet OAM-enabled port, you must first disable Ethernet
OAM on the port.
Configuring the Ethernet OAM connection detection
timers
After an Ethernet OAM connection is established, the Ethernet OAM entities on both sides exchange
Information OAMPDUs at a specified interval—handshake packet transmission interval—to check whether
the Ethernet OAM connection is normal. If an Ethernet OAM entity receives no Information OAMPDU
within the Ethernet OAM connection timeout time, the Ethernet OAM connection is considered
disconnected.
By adjusting the handshake packet transmission interval and the connection timeout timer, you can
change the detection time resolution for Ethernet OAM connections.
Follow these steps to configure the Ethernet OAM connection detection timers:

Optional

CAUTION:
After the timeout timer of an Ethernet OAM connection expires, the local OAM entity ages out its
connection with the peer OAM entity, causing the OAM connection to be disconnected. HP
recommends setting the connection timeout timer to at least five times the handshake packet
transmission interval, ensuring the stability of Ethernet OAM connections.
Configuring link monitoring
NOTE:
After Ethernet OAM connections are established, the link monitoring periods and thresholds configured
in this section take effect on all Ethernet ports automatically.
