ethernet oam lfm link-monitor symbol-period
Syntax
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 ]
Release Information
Command introduced in JunosE Release 11.1.0.
Description
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. |
Options
- 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
