SNMP versions and communication security

For the Output Manager SNMP service to communicate with a printing device, the security configuration must match between Output Manager and the device.

Output Manager supports SNMP versions 1 (SNMPv1), 2 (SNMPv2c), and 3 (SNMPv3). SNMPv1 and SNMPv2c use a community name for security. The Output Manager SNMP service is installed with a default community name of public. Output Manager uses the default community name during device detection and stores it with the new Output Manager device. Subsequent communication with the device uses the community name that is stored with the Output Manager device. To change the community name for a device, change it on the physical device and in the Output Manager Device Configuration dialog.

SNMP communicates with SNMPv3-enabled devices with a matching user name, authentication password, and protocol configured between the devices and Output Manager. To encrypt the data being communicated, use a matching encryption password and protocol.

If Output Manager does not communicate with devices through SNMPv3 with matching user names, authentication passwords, and protocols, include a remote engine context name in the configuration settings.

You can specify global SNMPv3 settings to communicate with all SNMPv3-enabled devices. If a device does not allow you to change SNMPv3 settings such as user name, authentication protocol, and encryption algorithm, you can override the SNMPv3 settings for the device on the Device Configuration dialog box accessible through the Devices application.
