After completing the configuration, you may query alarm events on the NMS. On the monitored device,
alarm event messages are displayed when events occur. The following is a sample output:
[Sysname]
#Aug 27 16:31:34:12 2005 Sysname RMON/2/ALARMFALL:Trap 1.3.6.1.2.1.16.0.2 Alarm table 1
monitors 1.3.6.1.2.1.16.1.1.1.4.1 with sample type 2,has sampled alarm value 0 less than(or
=) 50.
Private Alarm Group Configuration Example
Network requirements
As shown in Figure 1-4 , monitor the utilization rate of interface GigabitEthernet 2/0/1 when it is receiving
packets. When the utilization rate is higher than 80%, the system logs the event locally and sends a trap
to the NMS; when the utilization rate is lower than 5%, the system only logs the event locally.

Configuration procedure
# Configure the SNMP parameters. (Note that, parameter values configured on the agent must be the
same with the following configured on the NMS: suppose SNMPv3 is enabled on the NMS, the user
name is v3user , the IP address of the NMS is 1.1.1.2 , authentication protocol is MD5 , authorization
password is authkey , the privacy protocol is DES56 , and the privacy password is prikey .)
