The Errored Frame Event TLV counts the number of errored frames detected during
the specified period.
host1(config-if)#ethernet oam lfm link-monitor frame-seconds threshold high 600
In this case, a low error frame threshold of 600 frames is set. When this threshold
is exceeded, an Errored Frame Event TLV is sent to the remote peer.
b. Configure a high threshold value for frame errors, which when exceeded triggers
an action.
host1(config-if)#ethernet oam lfm link-monitor frame-seconds threshold high 60
In this case, a high error frame threshold of 60 frames is set. When this threshold
is exceeded, the action configured on the interface using the ethernet oam lfm
high-threshold action command is taken.
c. Configure a period of time during which error frames are counted for both high and
low threshold settings. The time duration is specified in hundred millisecond units.
host1(config-if)#ethernet oam lfm link-monitor frame-seconds window 10
In this case, the window during which error frames are counted is set as 10 hundred
millisecond units. The configured window is valid for both high and low threshold
settings. The high and low threshold settings are reset whenever a new window,
during which errors are counted, commences.
d. Configure a low threshold value for errored frame seconds, which causes an Errored
Frame Seconds Summary Event TLV to be sent to the OAM entity when the
threshold is exceeded. The Errored Frame Seconds Summary Event TLV counts
the number of errored frame seconds that occurred during the specified period.
An errored frame second is any 1-second period that has at least one errored frame.
host1(config-if)#ethernet oam lfm link-monitor frame-seconds-summary threshold
low 60
In this case, a low errored frame seconds threshold of 60 frame seconds is set.
When this threshold is exceeded, an Errored Frame Seconds Summary Event TLV
in an Event Notification OAM PDU is sent from the local OAM entity to the remote
peer.
e. Configure a high threshold value for errored frame seconds, which when exceeded
triggers an action.
host1(config-if)#ethernet oam lfm link-monitor frame-seconds-summary threshold
high 6
In this case, a high threshold of 6 errored frame seconds is set. When this threshold
is exceeded, the action configured on the interface using the ethernet oam lfm
high-threshold action command is taken.
f. Specify a period of time in which frame seconds summary error events are counted
for both high and low threshold settings. The time period used for counting events
is specified in seconds.
