3.19 Traps
While a management station can poll, at fixed time interval, all the agents it knows for some key
information, each agent is responsible for notifying the management station of any alarm
condition. These events are communicated in SNMP messages known as traps.
The following parameters should be set in order to correctly configure traps:
 SNMP Agent Port: 162.
 SNMP Agent Transport protocol: IP/UDP.
 Variable
o OID: 1.3.6.1.4.1.21678.200.13.
o Value(gauge): 32 Bit
3.19.1 Configuring traps
Use Java (refer to Network and Alarms paragraphs for further information) or SNMP user
interfaces to configure traps.
The configuration of traps is performed through the setting of a trap alarm mask, by means of
leaves housed in the echo_AlarmTrap node (refer to Configuring alarms paragraph), and
through the setting of the destination IP Address of the receiving management stations, by
means of leaves housed in the echo_Network node as shown in next figure.
