E.g. if you want to enable the GPS Lock and No TS Input alarms of a generic alarm mask,
set the decimal value of 33,570,816 that corresponds to a binary value of
0000 0010 0000 0000 0100 0000 0000 0000.
3.3.6 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: 1.3.6.1.4.1.21678.186.13.
o Value(gauge): 32 Bit
3.3.7 Configuring traps
Use Java (refer to Network and Alarms paragraphs for further information) or SNMP user
interfaces to configure traps.
