Congure SNMP users
Congure user access to the SNMP agent on the switch using group membership. Assign each user to a group and congure SNMPv3-
specic authentication and encryption settings, and optionally, localized security keys and ACL-based access. Re-enter the command
multiple times to congure SNMP security settings for all users.

[priv {des | aes}]] [localized] [access acl-name] [remote ip-address udp-port port-number]]
The group to which a user is assigned determines the user's access privilege. To congure a group's access privilege — read, write, and
notify — to the switch, use the snmp-server group command. The security model for SNMPv3 provides the strongest security with
user authentication and packet encryption.
No default values exist for SNMPv3 authentication and privacy algorithms and passwords. If you forget a password, you cannot recover it
— you must recongure the user. You can specify either a plain-text password or an encrypted cypher-text password. In either case, the
password stores in the conguration in encrypted form and displays as encrypted in show running-config snmp output.
A localized authentication or privacy key is more complex and provides greater privacy protection. Localized keys are generated using the
engine ID of the switch. For this reason, you cannot use the localized SNMP security passwords in the conguration le on another switch.
For more information, see Congure SNMP engine ID. To display the localized authentication and privacy keys in an SNMPv3 user
conguration, use the show running-configuration snmp command.
To limit user access to the SNMP agent on the switch, enter an access acl-name value. In IPv6 ACLs, SNMP supports only IPv6 and
UDP types. TCP, ICMP, and port rules are not supported.
To display the congured SNMP users, use the show snmp user command.
