Transceiver Threshold Configuration
– 1207 –
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.
◆ If trap messages are enabled with the transceiver-threshold-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.
◆ 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 enabled by the transceiver-threshold-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
transceiver-threshold rx-power {high-alarm | high-warning |
low-alarm | low-warning} threshold-value
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.
