6-1

The ATX sends trap PDUs to an SNMP Manager, using a pre-
configured SNMP Manager IP address. (See 

configNMSAddress

 in the 

ATX MIB Reference Guide). If no address has been pre-configured, 
then the ATX sends the traps to the source IP address of the last 
SNMP datagram received from an SNMP Manager. If no address 
has been pre-configured, and if no datagrams have been received 
since the ATX was booted, then the ATX 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 ATX may be configured to 
send an additional copy of each Trap PDU to a UDP port number 
you specify. (See 

sysTrapPort

 in the ATX MIB Reference Guide.) 

 •

coldStart

 (0) – An ATX has re-started, and the SNMP 

Manager's copy of the ATX's configuration may be incorrect.

 •

warmStart

 (1) – Not used by the ATX.

linkDown

 (2) – A port has failed, and the ATX'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 ATX'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
