7: Operations, Administration & Maintenance
Enable OAM protocol
Enable the passive or active OAM 802.3AH protocol for this OAM instance. An active instance will immediately start to
send information OAMPDUs associated with the discovery process.
Active Mode / Passive Mode
Select the mode of operation for the OAM instance.
• Passive: Listens for OAMPDUs and replies once it starts receiving them.
• Active: Immediately searches for an OAM peer by sending OAMPDUs.
Max OAM PDU size
Specify the maximum frame size the OAM instance will use. This enables you to limit the impact of the extra OAM traffic
on a link that is already heavily loaded.
This unit supports loopback
Enable this option to react to loopback requests from the OAM peer.
This unit supports events
Enable this option to issue event OAMPDUs when needed.
This unit supports variable responses
Enable this option to respond to OAMPDUs requests.
Number of Events re-transmitted
Specify the number of times an event is re-transmitted to ensure its reception by the peer. This setting is only valid if This
unit supports events is enabled.
Errored Frame Event (EFE) Threshold and window
Specify the threshold setting that defines the number of frame errors that must be detected in a given period to trigger the
transmission of an event.
The window setting defines the time, in seconds, of the period.
A frame error is an error detected at the layer 2, or MAC level. This can be caused by various types of errors including,
but not limited to, CRC errors, short frames, long frames, etc.
Errored Frame Period Event (EFPE) Threshold and window
Specify the threshold setting that defines the number of frame errors that must be detected in a given period to trigger the
transmission of an event.
The window setting defines the number of frames that make up a period. Using a number of frames instead of a time
period, as in EFE, means that this event is generated based on the ratio of bad frames versus good frames.
A frame error is an error detected at the layer 2, or MAC, level. This can be caused by various types of errors including,
but not limited to: CRC errors, short frames, long frames, etc.
