Cisco IOS XE Release 3.3SE

This command was implemented in Cisco IOS XE Release 3.3SE.

Usage Guidelines

An SNMP user must be part of an SNMP group, as configured using the snmp-server user username group-name command.

When the usernameargument is not entered, the show snmp usercommand displays information about all configured users. If you specify the usernameargument, if one or more users of that name exists, the information pertaining to those users is displayed. Because this command displays users configured with the SNMP engine ID of the local agent and other engine IDs, there can be multiple users with the same username.

When configuring SNMP, you may see the logging message “Configuring snmpv3 USM user.” USM stands for the User-based Security Model for version 3 of the Simple Network Management Protocol (SNMPv3). For further information on the USM, see RFC 2574.

Examples

The following is sample output from the show snmp user command. The output indicates the username as authuser, the engine ID string as 00000009020000000C025808, and the storage type as nonvolatile:

Router# show snmp user
 authuser
User name: authuser 
Engine ID: 00000009020000000C025808 
storage-type: nonvolatile       active access-list: 10
