Chapter 45 Access Control 45.3.6 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. Figure 223 Management > Access Control > SNMP > User The following table describes the labels in this screen. Table 152 Management > Access Control > SNMP > User 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 Security Level Specify the username of a login account on the Switch. 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. Authentication 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. 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. XGS4700-48F User's Guide 405
