Command Usage
• 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.
• 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.
• 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.
• Trap messages configured by this command are sent to any management station configured by
the
snmp-server host command.
• This command only applies to transceiver vendor "BROCADE".
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 sends a trap when the power level of the received signal falls outside of the
specified thresholds.
Syntax
transceiver-threshold rx-power {high-alarm | high-warning | low-alarm | low-warning}
threshold-value
high-alarm – Sends an alarm message when the high power threshold is crossed.
high-warning – Sends a warning message when the high power threshold is crossed.
low-alarm – Sends an alarm message when the low power threshold is crossed.
low-warning – Sends a warning message when the low power threshold is crossed.
threshold-value – The power threshold of the received signal. (Range: -9999 - 9999 in
units of 0.01 dBm)
Default Setting
