ethernet oam lfm link-monitor symbol-period { threshold { high { highFrames | none } |
low lowFrames } | window period }
no ethernet oam lfm link-monitor symbol-period [ threshold { high { highFrames | none
} | low lowFrames } | window period ]
Command introduced in JunosE Release 11.1.0.
Configures a threshold value for symbol error events that triggers an action or causes an
Error Symbol Period TLV to be sent to the OAM entity, or a period of time in which symbol
error events are counted. The no version disables monitoring of received symbol error
events.
NOTE: You can configure this command multiple times to configure
combinations of high and low threshold values or a window period for frame
error events.
link-monitor—Configures link monitoring parameters. Link monitoring operations start
automatically when Ethernet OAM is enabled on an interface. When link monitoring
operations are disabled, the interface does not actively send or receive Event Notification
OAM PDUs
symbol-period—Configures the threshold value or window for symbol error events
threshold—Configures a period or a value at, above, or below which an action is triggered
highSymbols—Integer in the range 1–65535 that is the high threshold in number of
symbol error seconds, which when exceeded causes an action to be triggered. The
action that the local OAM entity performs when the high threshold value is exceeded
depends on the value configured using the ethernet oam lfm high-threshold command.
There is no default value. If you specify a high threshold option for frame period
summary error events, you must also enter the number of frames, which when exceeded
causes the configured action to be taken
none—Removes the high threshold value for symbol error events
lowSymbols—Integer in the range 0–65535 that is the low threshold in number of
symbol error seconds, which when exceeded causes an Error Symbol Period TLV to
be sent to the peer; default value is 0 symbol error seconds. If you do not configure a
low threshold for symbol error events, the Link Fault critical event PDU is not sent to
the peer
period—A window and period of time during which symbol error events are counted.
Integer in the range 1–60 seconds that is the monitoring period for symbol errors; there
is no default value
