# Get the traffic statistics from the NMS through SNMP. (Details not shown.)
Alarm function configuration example
Network requirements
, configure the device to monitor the incoming traffic statistic on
Ten-GigabitEthernet 1/0/1, and send RMON alarms when the following events occur:
•
The 5-second delta sample for the traffic statistic crosses the rising threshold (100).
•
The 5-second delta sample for the traffic statistic drops below the falling threshold (50).

NOTE:
1.3.6.1.2.1.16.1.1.1.4.1 is the object instance for Ten-GigabitEthernet 1/0/1, where
1.3.6.1.2.1.16.1.1.1.4 represents the object for total incoming traffic statistics, and 1 is the RMON
Ethernet statistics entry index for Ten-GigabitEthernet 1/0/1.
