Trap messages configured by this command are sent to any management
station configured as an SNMP trap manager using the Administration >
SNMP (Configure Trap) page.
Note:
Trap messages for transceiver thresholds are disabled by default. To send a
trap when any of the transceivers operational values fall outside of specified
thresholds, use the transceiver-monitor command in the CLI.
Web Interface
To configure threshold values for optical transceivers:
1.
Click Interface, Port, Transceiver.
2.
Select a port from the scroll-down list.
3.
Set the switch to send a trap based on default or manual settings.
4.
Set alarm and warning thresholds if manual configuration is used.
5.
Click Apply.

Performing
Cable Diagnostics
Use the Interface > Port > Cable Test page to test the cable attached to a port. The
cable test will check for any cable faults (short, open, etc.). If a fault is found, the
switch reports the length to the fault. Otherwise, it reports the cable length. It can
be used to determine the quality of the cable, connectors, and terminations.
Problems such as opens, shorts, and cable impedance mismatch can be diagnosed
with this test.
Command Usage
Cable diagnostics are performed using Digital Signal Processing (DSP) test
methods. DSP analyses the cable by sending a pulsed signal into the cable, and
then examining the reflection of that pulse.
Cable diagnostics can only be performed on twisted-pair media.
