Chapter 34 Access Control Table 108 Management > Access Control > SNMP (continued) LABEL DESCRIPTION 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. Authenticati on Privacy 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. Specify the encryption method for SNMP communication from this user. You can choose one of the following: Apply Cancel • 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. Click Apply to save your changes to the Switch's run-time memory. The Switch 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 nonvolatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. MGS-3712/MGS-3712F User's Guide 317
