The unit sends Trap PDUs to the NMS, using the pre-configured NMS IP address 
(see configNMSAddress). If no address has been pre-configured, then the unit 
sends the Traps to the source IP address of the last SNMP datagram received 
from an NMS. If no address has been pre-configured, and if no datagrams have 
been received since the unit was booted, then the unit uses the broadcast IP 
address.

The Trap PDUs are sent from source UDP port number 161, to destination UDP 
port number 162, which are the SNMP standard numbers reserved for Trap 
PDUs. The unit may be configured to send an additional copy of each Trap PDU 
to a user specified destination UDP port number (see sysTrapPort).

SNMP defines seven different traps, which are described below.

•

coldStart (0) – A unit has re-started, and the NMS’s copy of the unit’s 
configuration may be incorrect.

•

warmStart (1) – Not used by the unit.

•

linkDown (2) – A port has failed, and the unit’s local management agent has 
disabled usage of the port. The “variable-bindings” portion of the trap 
contains the ifIndex of the port.

•

linkUp(3) – A port has come back to life, and the unit’s local management 
agent has re-enabled usage of the port. The “variable-bindings” portion of the 
trap contains the ifIndex of the port.

•

authenticationFailure(4) – This trap is generated whenever the community 
name in a PDU does not match the corresponding password. All SetRequest 
PDUs must match the configAnyPass (refer to the description of 
configGetPass for SetRequest exceptions), GetRequest PDUs must match 
either the configGetPass or the configAnyPass. The GetRequest exception is 
for one of the debugging attributes; those PDUs must always provide the 
configAnyPass.
