for authentication with managers using SNMP v3 and associate them to SNMP groups. An SNMP user is
an SNMP manager.

The following table describes the labels in this screen.
Apply Click Apply to save your changes to the OLT’s run-time memory. The OLT loses these changes
if it is turned off or loses power, so use the Save link on the top navigation panel to save your
changes to the non-volatile memory when you are done configuring.

LABEL DESCRIPTION
User Information
Note: Use the username and password of the login accounts you specify in this
screen to create accounts on the SNMP v3 manager.
Username Specify the username of a login account on the OLT.
Security Level Select whether you want to implement authentication and/or encryption for SNMP
communication from this user. Choose:
• noauth -to use the username as the password string to send to the SNMP manager. This is
equivalent to the Get, Set and Trap Community in SNMP v2c. This is the lowest security
level.
• auth - to implement an authentication algorithm for SNMP messages sent by this user.
• priv - to implement authentication and encryption for SNMP messages sent by this user.
This is the highest security level.
Note: The settings on the SNMP manager must be set at the same security level or
higher than the security level settings on the OLT.
Authentication Select an authentication algorithm. 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.
Password Enter the password of up to 32 ASCII characters for SNMP user authentication.
