46.3.6 Configuring SNMP User
From the SNMP screen, click User to view the screen as shown. Use the User
screen to create SNMP users 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.

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 Switch.
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
Switch.
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.
