SNMPv3 USM User Table Information
The User-based Security Model (USM) in SNMPv3 provides security services such as authentication and privacy of messages. This security model uses a defined set of user identities displayed in the USM User Table Information Parameters (/info/sys/snmpv3/usm). The USM user table contains information such as:
*The user name.
*A security name in the form of a string whose format is independent of the security model.
*An authentication protocol, which is an indication that the messages sent on behalf of the user can be authenticated.
*The privacy protocol.
