ethernet oam lfm link-monitor symbol-period
Syntax
[ 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
