Display SNMP groups OS10# show snmp group groupname version notifyview readview groupname version security level notifyview readview writeview : v2group : 2c : GetsSets : readview : v3group : 3 : priv : alltraps : readview : writeview Configure SNMP users Configure user access to the SNMP agent on the switch using group membership. Assign each user to a group and configure SNMPv3specific authentication and encryption settings, and optionally, localized security keys and ACL-based access. Re-enter the command multiple times to configure SNMP security settings for all users. snmp-server user user-name group-name security-model [[noauth | auth {md5 | sha} authpassword] [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 configure 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 reconfigure the user. You can specify either a plain-text password or an encrypted cypher-text password. In either case, the password stores in the configuration in encrypted form and displays as encrypted in the 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 configuration file on another switch. For more information, see Configure SNMP engine ID. To display the localized authentication and privacy keys in an SNMPv3 user configuration, 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 configured SNMP users, use the show snmp user command.
