Interfaces
Context config>port>ethernet>efm-oam>link-monitoring>errored-frame-period
Description Defines the size of the window based on a packet receive rate. The minimum serviceable rate is the number
of minimum size packets that can be received in one second. The window receive count value will be polled
at a minimum one second intervals to see if the window size has been reached. Errors are accumulated until
the end of the window. At the end of the window the actual errors are compared to the thresholds to deter-
mine if a threshold has been crossed. There is no mid-window threshold checking. The window represents
a unique non-overlapping period of time.
Parameters packets — The number of received packets.
Values
Default
errored-frame-seconds
Syntax errored-frame-seconds
Context config>port>ethernet>efm-oam>link-monitoring
Description The context used to define errored frame seconds parameters including thresholds, and windows of time to
which the error count will be compared. An errored second is any second in which a single frame error
occurred. An errored frame is counted when there is any frame error detected by the Ethernet physical layer.
This excludes jumbo frames above 9192 bytes that are dropped prior to this function.
sd-threshold
Syntax sd-threshold errored-frames
[no] sd-threshold
Context config>port>ethernet>efm-oam>link-monitoring>errored-frame-seconds
Description The option is used to define the number of errored frame seconds within the configured window which indi-
cates the port has gone beyond an acceptable error rate and should be considered degraded. This is a first
level warning that a port may be suspect. This event is raised when the error count is equal to or greater than
the configured threshold. This is an information log event message only and will be recorded in the Port
event index but has no port level actions. This value must be lower than or equal to the sf-threshold value.
The no value of this option disables the sd-threshold
Default [no] sd-threshold
Parameters
errored-seconds — The number of errored seconds within the configured window which indicates the port
has become degraded.
