Configuring Link Monitoring; Configuring Errored Symbol Event Detection - HPE FlexFabric 5700 Series Configuration Manual

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. As a best practice
to keep the Ethernet OAM connections stable, set the connection timeout timer to be a minimum of
five times the handshake packet transmission interval.
To configure the Ethernet OAM connection detection timers globally:
Step
5. Enter system view.
6. Configure the Ethernet OAM
handshake packet
transmission interval.
7. Configure the Ethernet OAM
connection timeout timer.
To configure the Ethernet OAM connection detection timers on a port:
Step
1. Enter system view.
2. Enter Layer 2/Layer 3
Ethernet port view.
3. Configure the Ethernet OAM
handshake packet
transmission interval.
4. Configure the Ethernet OAM
connection timeout timer.

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.
To configure errored symbol event detection globally:
Step
1. Enter system view.
2. Configure the errored symbol
event detection window.
3. Configure the errored symbol
event triggering threshold.
