# Get the traffic statistics from the NMS through SNMP. (Details not shown.)
Alarm function configuration example
Network requirements
As shown in Figure 33, configure the device to monitor the incoming traffic statistic on
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).

# Configure the SNMP agent (the device) with the same SNMP settings as the NMS at 1.1.1.2. This
example uses SNMPv1, read community public, and write community private.

4
represents the object for total incoming traffic statistics, and 1 is the RMON Ethernet statistics entry
index for GigabitEthernet 1/0/1.
