connection. 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.
You can configure this command in system view or port view. The configuration in system view takes effect
on all ports, and the configuration in port view takes effect on the specified port. For a port, the
configuration in port view takes precedence.
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 disconnect. To keep the Ethernet
OAM connections stable, HP recommends that you set the connection timeout timer to be at least five
times the handshake packet transmission interval.

By default, an interface uses the

By default, an interface uses the
value configured globally.
Configuring link monitoring
After Ethernet OAM connections are established, the link monitoring periods and thresholds configured
in this section automatically take effect on all Ethernet ports.
Configuring errored symbol event detection
An errored symbol event occurs when the number of detected symbol errors in the detection window
(specified number of received symbols) exceeds the predefined threshold.
You can configure this command in system view or port view. The configuration in system view takes effect
on all ports, and the configuration in port view takes effect on the specified port. For a port, the
configuration in port view takes precedence.
