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 local user; otherwise it’s remote user.
User Name

The allowed string length is 1 to 32, and the allowed content is the
ASCII characters from 33 to 126.

Ensure that the value is set correctly at the time of entry creation.
