It actually contains three elements - an enterprise-OID and So an SNMPv1 trap shouldĬontain two values - the enterprise OID and the value of the trap itself, right? Unsurprisingly, the format of a trap request follows the format of theĬorresponding SMI definition fairly closely. How are they represented as SNMP requests? OK - so that describes how notifications are defined in a MIB file.

There are two ways of defining a notification - one used in SMIv1 MIBsĪnd one used in SMIv2 MIBs. 4.7 Operating System Specific Tutorials.
