5. Follow the directions for Setting up the Access Control List (below).
Setting Up SNMP v3 Community Definitions
Setting up the v3 user definition is very similar to the v1/v2c community definitions. The difference is the addition of a user
security level and a user password.
1. To create a new SNMP v3 user definition, click the Add button in the SNMP v3 User Definitions area.
2. Specify a user name in the Username field.
3. Select a security level from the Security pull-down menu. Select from the following choices:
4. Click in the OID cell of the table. Either use the OID (Object Identifier) pull-down menu to select the default OID or type
in an OID number into the field. (The format is in a numerical dot notation, and valid numbers can be found within the
MIB.)
If is selected, the community will have access to all the OIDs (SNMP parameters) in the SNMP Management Information
Base (MIB) file. If a custom OID is entered, the administrator can allow access to specific OIDs in the MIB to certain
communities.
5. Click the Password button in the cell and the Password Settings screen appears.
11. Use the Access pull-down menu to specify read-only (R) access or read/write (RW) access for the community. Read-
only access allows a remote device to retrieve switch information, while read/write access also allows a remote device
to modify switch settings.
12. Follow the directions for setting up the Access Control List (below).
Setting Up the Access Control List
To set up the Access Control list as specified by a range of IP addresses, click the SNMP Access Control button at the
bottom of the SNMP Access screen. The SNMP Access Control screen appears:
noAuth

AuthNoPriv
(authorization without privacy) Requires the user to login, however no encryption is used
AuthPriv
(authorization with privacy) Requires the user to login and encryption is used
6. Select an Authentication Algorithm
from the drop-down menu, either MD5 or
SHA1.
7. Type in an Authentication Password.
8. Select a Privacy Algorithm from the drop-
down menu. The options include:
• DES
• 3DES
• AES 128-bit
• AES 192-bit
• AES 256-bit
9. Type in a Privacy Password that matches
the algorithm.
10. Click Ok, when done.
