1.  Introduction

   SNMP and SYSLOG are two widely used protocols to communicate event
   notifications.  Although co-existence of several management protocols
   in one operational environment is possible, certain environments
   require that all event notifications be collected by a single system
   daemon, such as a SYSLOG collector or an SNMP notification receiver,
   via a single management protocol.  In such environments, it is
   necessary to translate event notifications between management
   protocols.

   The latest version of SYSLOG, specified in [RFC5424], supports a
   structured data element format.  Structured data elements allow us to
   map between SNMP notifications and SYSLOG messages without losing
   information.  In this memo, we specify a concrete mapping from SNMP
   event notifications [RFC3416] into SYSLOG messages [RFC5424].  We
   specify how the SYSLOG message format should be utilized to carry the
   information contained in an SNMP notification message.  A new SYSLOG
   structured data element is defined, which carries the PDU portion of
   an SNMP notification message.

1.1.  Conventions

   A system that has the capability of receiving SNMP notification
   messages from an SNMP notification originator and sending the SNMP
   data contained inside in a SYSLOG message format to a SYSLOG
   collector is referred to in this memo as an "SNMP-to-SYSLOG
   translator".  By definition, such a system should have an SNMP
