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.

Table 8 User Table parameters

Field

Description

User Name

This is a string that represents the name of the user that you can use to access the

 

switch.

Protocol

This indicates whether messages sent on behalf of this user are protected from

 

disclosure using a privacy protocol. switch software supports DES algorithm for privacy.

 

The software also supports two authentication algorithms: MD5 and HMAC-SHA.
