The User-based Security Model (USM) in SNMPv3 provides security services such as authentication and privacy of
messages. This security model makes use of a defined set of user identities displayed in the USM user table. The
USM user table contains information like:
•
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
The following table describes the SNMPv3 User Table information.

Protocol

a privacy protocol. switch software supports DES algorithm for privacy. The software also
supports two authentication algorithms: MD5 and HMAC-SHA.
