12.8.3 SNMP Traps
SNMP traps are messages sent by the agents of each managed device to the SNMP manager. These
messages inform the administrator of events in data networks handled by the device. The NWA can
send the following traps to the SNMP manager.
Some traps include an SNMP interface index. The following table maps the SNMP interface indexes
to the NWA’s physical and virtual ports.
