Monitoring and Controlling the Machine with SNMP
Simple Network Management Protocol (SNMP) is a protocol for monitoring and controlling communication devices in a
network by using Management Information Base (MIB). The machine supports SNMPv1 and security-enhanced
SNMPv3. You can check the status of the machine from a computer when you print documents or use the Remote UI.
You can enable either SNMPv1 or SNMPv3, or both at the same time. Specify the settings for each version to suit your
network environment and the purpose of use.
SNMPv1 uses information called "community" to define the scope of SNMP communication. Because this
information is exposed to the network in plain text, your network will be vulnerable to attacks. If you want to
ensure network security, disable SNMPv1 and use SNMPv3.
With SNMPv3, you can implement network device management that is protected by robust security features.
Note that TLS must be enabled for the Remote UI before configuring SNMPv3 (
Certificate for TLS(P. 160) ).
The machine does not support the trap notification feature of SNMP.
To change the port number of SNMP, see
SNMP management software, when installed on a computer on the network, enables you to configure,
monitor, and control the machine remotely from the computer. For more information, see the instruction
manuals for your management software.
