Message
:
ALARM: Receive power is below specified threshold. Fiber trap intrusion may be in progress.
Meaning
: At
C6010 > Port 2
> DMI
tab, the Rx Power Intrusion Threshold setting was exceeded. With a
preset level for Rx Power on the Fiber port, if the DMI read value falls below this preset value, an
intrusion is suspected, and a trap is generated. Fiber optic cables can be vulnerable to tapping, with or
without physical intrusion into the optic cable light path.
Either the “Rx Pow
er Intrusion Threshold (μW)” setting is too
high, or an optical fiber may have been
tapped, which could allow the data stream to be intercepted.
Recovery
:
1.
Make sure that an intrusion did not cause the alarm; check with your organization’s security staff.
2.
Change the
Rx Power Intrusion Threshold
setting to a higher value:
a. From the x6010 Web interface, at
x6010
>
Port x
(SFP) >
DMI
tab, enter a lower threshold setting
and click
Save
and then click
Refresh
.
b. From the x6010 CLI, enter the
set dmi rx-power-preset-level
=xx command where xx is a lower
setting, and press the
Enter
key. See “
DMI (Diagnostic Maintenance Interface) Parameters
”.
3.
From the CLI, enter the command
reset all ports counters
and press the
Enter
key.
4.
If the problem persists, contact Technical Support.
