The page includes the following fields:
Object Description
• Delete
Check to delete the entry. It will be deleted during the next save.
• Engine ID
An octet string identifying the engine ID that this entry should belong
to. The string must contain an even number(in hexadecimal format)
with number of digits between 10 and 64, 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
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 ASCII
characters from 33 to 126.
