| Description | Ethernet OAM includes the ability to generate and receive
Event Notification OAMPDUs to indicate various link problems.
This table contains the mechanisms to enable Event
Notifications and configure the thresholds to generate the
standard Ethernet OAM events. There is one entry in the table
for every entry in cdot3OamTable that supports OAM events
(where cdot3OamFunctionsSupported includes the eventSupport
bit set). The values in the table are maintained across
changes to cdot3OamOperStatus.
The standard threshold crossing events are:
- Errored Symbol Period Event. Generated when the number of
symbol errors exceeds a threshold within a given window
defined by a number of symbols (for example, 1,000 symbols
out of 1,000,000 had errors).
- Errored Frame Period Event. Generated when the number of
frame errors exceeds a threshold within a given window
defined by a number of frames (for example, 10 frames out
of 1000 had errors).
- Errored Frame Event. Generated when the number of frame
errors exceeds a threshold within a given window defined
by a period of time (for example, 10 frames in 1 second
had errors).
- Errored Frame Seconds Summary Event. Generated when the
number of errored frame seconds exceeds a threshold within
a given time period (for example, 10 errored frame seconds
within the last 100 seconds). An errored frame second is
defined as a 1 second interval which had >0 frame errors.
There are other events (dying gasp, critical events) that are
not threshold crossing events but which can be
enabled/disabled via this table. |
