Setting Up User-Based Security (SNMPv3)

When setting up SNMPv3, you can set users up with one of the following three types of configuration for SNMP read/write operations.

Users are typically associated to an SNMP group with permissions provided, such as OID view.
  • noauth — no password or privacy. Select this option to set up a user with no password or privacy privileges. This setting is the basic configuration. Users must have a group and profile that do not require password privileges.
  • auth — password privileges. Select this option to set up a user with password authentication.
  • priv — password and privacy privileges. Select this option to set up a user with password and privacy privileges.

To set up user-based security (SNMPv3), use the following commands.

  • Configure the user with view privileges only (no password or privacy privileges).
    CONFIGURATION mode
    snmp-server user name group-name 3 noauth
  • Configure an SNMP group with view privileges only (no password or privacy privileges).
    CONFIGURATION mode
    snmp-server group group-name 3 noauth auth read name write name
  • Configure an SNMPv3 view.
    CONFIGURATION mode
    snmp-server view view-name oid-tree {included | excluded}
    NOTE To give a user read and write view privileges, repeat this step for each privilege type.
  • Configure the user with an authorization password (password privileges only).
    CONFIGURATION mode
    snmp-server user name group-name 3 noauth auth md5 auth-password
  • Configure an SNMP group (password privileges only).
    CONFIGURATION mode
    snmp-server group groupname {oid-tree} auth read name write name
  • Configure an SNMPv3 view.
    CONFIGURATION mode
    snmp-server view view-name 3 noauth {included | excluded}
    NOTE To give a user read and write privileges, repeat this step for each privilege type.
  • Configure an SNMP group (with password or privacy privileges).
    CONFIGURATION mode
    snmp-server group group-name {oid-tree} priv read name write name
  • Configure the user with a secure authorization password and privacy password.
    CONFIGURATION mode
    snmp-server user name group-name {oid-tree} auth md5 auth-password priv des56 priv password
  • Configure an SNMPv3 view.
    CONFIGURATION mode
    snmp-server view view-name oid-tree {included | excluded}
