Note:
z
An error signal event occurs when a period for error signal event detection expires
and the number of the signal errors occurred on an Ethernet port is larger than or
(equal to) the threshold for error signal event detection.
z
An error frame event occurs when a period for error frame event detection expires
and the number of the frame errors occurred on an Ethernet port is larger than (or
equal to) the threshold for error frame event detection.
z
A frame-percentage error event occurs when a period for frame-percentage error
event detection expires and the number of the frame errors occurred on an Ethernet
port is larger than (or equal to) the threshold for frame-percentage error event
detection.
z
As for frame-percentage error event detection, the system first uses the following
expression to convert the period for frame-percentage error event detection to the
maximum number of 64-byte frames that can be transmitted through an Ethernet
port in the period: bandwidth * period / (64 * 8 * 1000), where “bandwidth” is the port
bandwidth (in bps) and “period” is the configured period (in milliseconds).
z
A second-percentage error event occurs when a period for second-percentage error
event detection expires and the number of the error seconds of an Ethernet port is
larger than (or equal to) the threshold for second-percentage error event detection.
(A second is called an error second if error frames occur in the second.)
z
The periods and the thresholds configured apply to all the Ethernet ports on which
OAM connections are established.
