User Privacy Definition
However, if SNMPv3 is not listed in the supporting of the "Configuration" window, the "User
Privacy Definition" window will be not used for SNMP agent in the gateway. The "User Privacy
Definition" window provides 5 records of user privacy definition for user authentication and data
hashing and encryption. In SNMPv3, SNMP protocol supports user privacy feature additionally. By
referring to above setting diagram, there are 3 privacy modes: authPriv, authNoPriv and noAuthNoPriv.
At authPriv mode, User Name and Password are used for user authentication during logging in the
SNMP server. And, MD5 or SHA‐1 algorithm is chosen for data hashing and DES algorithm is for data
encryption. Additional Privacy Key is also used in data encryption. However, at authNoPriv mode, User
Name and Password are for user authentication to login SNMP server, MD5 or SHA‐1 algorithm is
chosen for data hashing and there is no need of Encryption and Privacy Key. At last, at noAuthNoPriv
mode, there is only User Name to be required to login the SNMP server. No matter which privacy mode
