Command Usage
â—†
If trap messages are enabled with the transceiver-monitor command, and a
high-threshold alarm or warning message is sent if the current value is greater
than or equal to the threshold, and the last sample value was less than the
threshold. After a rising event has been generated, another such event will not
be generated until the sampled value has fallen below the high threshold and
reaches the low threshold.
â—†
If trap messages are enabled with the transceiver-monitor command, and a
low-threshold alarm or warning message is sent if the current value is less than
or equal to the threshold, and the last sample value was greater than the
threshold. After a falling event has been generated, another such event will not
be generated until the sampled value has risen above the low threshold and
reaches the high threshold.
â—†
Threshold events are triggered as described above to avoid a hysteresis effect
which would continuously trigger event messages if the power level were to
fluctuate just above and below either the high threshold or the low threshold.
â—†
Trap messages enabled by the transceiver-monitor command are sent to any
management station configured by the snmp-server host command.
Example
The following example sets alarm thresholds for the transceiver current at port 1.
Console(config)interface ethernet 1/1
Console(config-if)#transceiver-threshold current low-alarm 100
Console(config-if)#transceiver-threshold rx-power high-alarm 700
Console#
transceiver-threshold
rx-power
This command sets thresholds for the transceiver power level of the received signal
which can be used to trigger an alarm or warning message.
Syntax

high-alarm
– Sets the high power threshold for an alarm message.
high-warning
– Sets the high power threshold for a warning message.
low-alarm
– Sets the low power threshold for an alarm message.
low-warning
– Sets the low power threshold for a warning message.
threshold-value – The power threshold of the received signal.
