24.3.5 Add SNMP V3 User
Click Add under SNMP V3 User Configuration in System > SNMP to create an SNMPv3 user for
authentication with managers using SNMP v3. Use the username and password of the login accounts
you specify in this screen to create accounts on the SNMP v3 manager.
Community 1/2 Type the trap community, which is the password sent with each trap to the SNMP manager.
The default is public and allows all requests.
Community 1/2
Authorization
Select the access rights to the trap community.
• read-write: The associated user can create and edit the trap community.
• read-only: The associated user can only read the trap community.
SNMPV3 Select the SNMP version for the Zyxel Device. The SNMP version on the Zyxel Device must
match the version on the SNMP manager. SNMPv3 (RFCs 3413 to 3415) provides secure
access by authenticating and encrypting data packets over the network. The Zyxel Device
uses your login password as the SNMPv3 authentication and encryption passphrase.
Note: Your login password must consist of at least 8 printable characters for
SNMPv3. An error message will display if your login password has fewer
characters.
Add Click this to create a new entry. Select an entry and click Add to create a new entry after
the selected entry.
Edit Double-click an entry or select it and click Edit to be able to modify the entry’s settings.
Remove To remove an entry, select it and click Remove. The Zyxel Device confirms you want to
remove it before doing so. Note that subsequent entries move up by one when you take this
action.
User This displays the name of the user object to be sent to the SNMP manager along with the
SNMP v3 trap.
Authentication This displays the authentication algorithm used for this entry. MD5 (Message Digest 5) and
SHA (Secure Hash Algorithm) are hash algorithms used to authenticate SNMP data. SHA
authentication is generally considered stronger than MD5, but is slower.
Privacy This displays the encryption method for SNMP communication from this user. Methods
available are:
• DES - Data Encryption Standard is a widely used (but breakable) method of data
encryption. It applies a 56-bit key to each 64-bit block of data.
• AES - Advanced Encryption Standard is another method for data encryption that also
uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
Apply Click Apply to save your changes back to the Zyxel Device.
Reset Click Reset to return the screen to its last-saved settings.
