SNMP
Simple Network Management Protocol (SNMP) is a set of rules that govern the
management of network devices, such as printing systems. These settings
determine the level of security when using the Auto Configure feature, and
prevent unauthorized printing to the SNMPv3 printing system. SNMP settings
must be set in the printer driver and in the printing system’s Command Center.
The following options are available:
SNMPv1/v2c
This option ensures successful Auto Configure communication using Read
community name and Write community name.
SNMPv3
This option ensures secure Auto Configure communication using a user
name and password. Authentication and privacy options are available by
selecting Settings.
Apply to other models
This option displays a list of installed printing systems to apply the selected
settings.
SNMPv3 Options
You can select options for secure communication with the printing system.
Authentication
This option provides an algorithm to check that a transferred file has arrived
intact. Message Digest 5 (MD5) and Secure Hash Algorithm 1 (SHA1) are hash
algorithms used to authenticate packet data.
MD5
This option provides a cryptographic hash function with a 128 bit hash value.
It adds security and protection against Gateway Load Balancing Protocol
(GLBP)-spoofing software.
SHA1
This option produces a message digest that is 160 bits long. SHA1 is the
successor to MD5.
Privacy
This option uses encryption for secure communication. It is available after you
select the Authentication option. You may select one Privacy option.
DES
This option uses the Data Encryption Standard for encryption. DES turns
cleartext into ciphertext via an encryption algorithm. It encrypts and decrypts
data using 8-byte blocks and a 56-bit key.
AES
This option uses the Advanced Encryption Standard for encryption. AES is a
symmetric block cipher that can process data blocks of 128 bits, using cipher
keys with lengths of 128, 192, and 256 bits. It is more secure than DES.
Selecting SNMP Settings
These settings in the driver must be set to match the settings in the printing
system’s Command Center.
