• The access point enables SNMP v3 users to be assigned to three pre-
defined groups. Other groups cannot be defined. The available groups
are:
– RO - A read-only group using no authentication and no data
encryption. Users in this group use no security, either authenti­
cation or encryption, in SNMP messages they send to the agent.
This is the same as SNMP v1 or SNMP v2c.
– RWAuth - A read/write group using authentication, but no data
encryption. Users in this group send SNMP messages that use an
MD5 password for authentication, but not a DES key for encryp­
tion.
– RWPriv - A read/write group using authentication and data
encryption. Users in this group send SNMP messages that use an
MD5 password for authentication and a DES key for encryption.
Both the MD5 password and DES key must be defined.
• The command prompts for the following information to configure an
SNMP v3 user:
User Name - A user-defined string for the SNMP user. (32 charac­
–
ters maximum, case sensitive)
Group Name - The name of the SNMP group to which the user is
–
assigned (32 characters maximum, case sensitive). There are
three pre-defined groups: RO, RWAuth, or RWPriv.
Authtype - The authentication type used for user authentication:
–
md5 or none.
Passphrase - The user password required when authentication is
–
used (8 – 32 ASCII characters).
Privacy - The encryption type used for SNMP data encryption: des
–
or none.
Passphrase - The user key required when data encryption is used
–
(8 – 32 ASCII characters).
• Users must be assigned to groups that have the same security levels.
If a user who has "AuthPriv" security (uses authentication and encryp­
tion) is assigned to a read-only (RO) group, the user will not be able
to access the database. An AuthPriv user must be assigned to the
RWPriv group with the AuthPriv security level.
• To configure a user for the RWAuth group, you must select the
Authtype and an MD5 password.
• To configure a user for the RWPriv group, you must select the Authtype
as well as the Privacy type, and configure an MD5 password and a DES
key.
