Configuring basic Ethernet OAM functions
For Ethernet OAM connection establishment, an Ethernet OAM entity operates in active mode or passive
mode. Only an Ethernet OAM entity in active mode can initiate connection establishment. After Ethernet
OAM is enabled on an Ethernet port, according to its Ethernet OAM mode, the Ethernet port establishes
an Ethernet OAM connection with its peer port.
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 the 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.
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. H3C
recommends that you set the connection timeout timer to at least five times the handshake packet
transmission interval, ensuring the stability of Ethernet OAM connections.
