To avoid false alarms, do not execute the
alarm-port event alarm-in
or

The alarm output port issues an alarm in response to an incoming external alarm only if the
alarm-port event alarm-in command is executed on the device.
Examples
#Configure the alarm input port to identify the high level signal as an external alarm on member
devices 1, 2, and 3.
<Sysname> system-view

of IRF member devices by member ID. The slot-number2 argument must be greater than the

Usage guidelines
You can connect the alarm output port of the device to an alarm indicator (for example, an alarm light
or buzzer) or the alarm input port of another device. If you connect the port to the alarm input port of
another device, the devices are connected in series.
To monitor alarms from multiple devices, connect the devices in series, log in to each device, and
configure the same alarm signal for the interconnected alarm ports. For easy device alarm
management, choose a scheme from
Table 1 .
