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.

Figure 220   Management > Access Control > SNMP > User 

The following table describes the labels in this screen.

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.
