2.16 SNMP Setting Function 2 2.16.2 SNMP access authentication function If the settings of the Administrator mode are to be changed using SNMP from the PC, the user attempting to gain access is authenticated to be the Administrator of the machine by using the Write User Name and SNMP Password (auth-password, priv-password) of the SNMP v3 Write settings made in this machine. Operation of the network setting function and the SNMP password change function of the security control functions that can be used over the network using SNMP is granted to the Administrator who is identified by a matching SNMP password for the Write User Name. The entry of a wrong SNMP password (auth-password, priv-password) is counted as unauthorized access, if the Enhanced Security Mode is set to [ON]. If a wrong SNMP password (auth-password, priv-password) is entered a predetermined number of times (once to three times) or more set by the Administrator of the machine, the machine is set into an access lock state, rejecting any more logon attempts. To cancel the access lock state, perform the Release Setting by the Administrator of the machine. Reference - If [auth-password] has been selected for Security Level, hashing is used for the authentication informa- tion (auth-password) to be transmitted. The machine allows you to select either HMAC-MD5 or HMACSHA1 for hashing. - If [auth-password/priv-password] has been selected for Security Level, the authentication information (auth-password/priv-password) and data (object ID that specifies the object to be changed, value to be set, etc.) to be transmitted are used for hashing and encryption. The machine allows you to select either CBC-DES or CBC-AES for encryption. - For accessing the MIB, use the MIB browser corresponding to the above encryption algorithm. 2.16.3 SNMP v3 setting function The Administrator who has been authenticated through SNMP access authentication from the PC is allowed to operate the SNMP password change function. The entry of a wrong SNMP password (auth-password, priv-password) is counted as unauthorized access, if the Enhanced Security Mode is set to [ON]. If a wrong SNMP password (auth-password, priv-password) is entered a predetermined number of times (once to three times) or more set by the Administrator of the machine, the machine is set into an access lock state, rejecting any more logon attempts. To cancel the access lock state, perform the Release Setting by the Administrator of the machine. For the auth-password and priv-password, enter the password that meets the requirements of the Password Rules. For details of the Password Rules, see page 1-8. To change the setting, specify the corresponding object ID. See the table below for the setting items.
