SNMPv3 USM User Table information
The following command displays SNMPv3 user information:
show snmp-server v3 user
Command mode: All
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.
