NWA1121-NI User’s Guide

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 
NWA1121-NI 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 NWA1121-NI’s physical and virtual ports.

SNMP Traps

Generic Traps

coldStart 

1.3.6.1.6.3.1.1.5.1

This trap is sent after booting (power on). This trap is 
defined in RFC-1215.

authenticationFailure 
(defined in RFC-1215)

Note: snmpEnableAuthenTraps, OID 1.3.6.1.2.1.11.30 
(defined in RFC 1214 and RFC 1907) must be enabled 
on in order for the device to send authenticationFailure
