Interface Configuration (Ethernet)
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 1/25
Console(config-if)#transceiver-threshold current low-alarm 100
Console(config-if)#transceiver-threshold rx-power high-alarm 700
