Engine ID
An octet string identifying the engine ID that this entry should belong to. The string
must contain an even number between 10 and 64 hexadecimal digits, but all-zeros
and all-’F’s are not allowed. The SNMPv3 architecture uses the User-based Security
Model (USM) for message security and the View-based Access Control Model (VACM)
for access control. For the USM entry, the usmUserEngineID and usmUserName
are the entry’s keys. In a simple agent, usmUserEngineID is always that agent’s own
snmpEngineID value. The value can also take the value of the snmpEngineID of a
remote SNMP engine with which this user can communicate. In other words, if user
engine ID equal system engine ID then it is a local user; otherwise it’s a remote user.
User Name
A string identifying the user name that this entry should belong to. The allowed string
length is 1 to 32, and the allowed content is the ASCII characters from 33 to 126.
