2.18 SNMP Setting Function
2
2.18.2 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 ma-
chine, 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 HMAC-
SHA1 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. Set [AES-128] for Encryption Algorithm
and [SHA-1] for Authentication Algorithm.
- For accessing the MIB, use the MIB browser corresponding to the above encryption algorithm.
2.18.3 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 ma-
chine, 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 meet the Password Rules. For details of
the Password Rules, see page 1-11.
To change the setting, specify the corresponding object ID. See the table below for the setting items.
2.18.4 SNMP network setting function
The Administrator who has been authenticated through SNMP access authentication from the PC is allowed
to operate the network setting function. To change the setting, specify the corresponding object ID. See the
table below for the setting items.
