SNMPv3 Enabled Devices
Devices that have SNMPv3 fully enabled can be discovered by HP Web Jetadmin. To discover these devices,
enable Discover SNMP v3 devices in Tools > Options > Device Management > Device Discovery > General.
HP Web Jetadmin requires SNMPv3 credentials for these devices in order for them to be discovered. There are
two ways HP Web Jetadmin can become aware of device SNMPv3 credentials:
●
HP Web Jetadmin is used to enable SNMPv3 and also configure the SNMPv3 credentials onto the
devices. In this case, HP Web Jetadmin stores the credentials into its credential store and uses them
whenever device communication is required. HP Web Jetadmin also marks these devices as SNMPv3-
enabled and remembers to use the credentials and SNMPv3 whenever communication is required.
●
HP Web Jetadmin has had SNMPv3 credentials added to the Global credentials store and these
credentials match those credential values on the devices. In this case, HP Web Jetadmin is being made
aware of credential values that work for devices that are SNMPv3-enabled. When one of these devices
is encountered, HP Web Jetadmin will try the credential values that are configured using the option
SNMPv3 Credentials in Tools > Options > Shared > Credentials. If the credential values work and
HP Web Jetadmin is able to communicate with the devices, the credential values will be stored
individually for each device.
Devices that were discovered through SNMPv1 and have had SNMPv3 enabled through some other means
such as Embedded Web Server or another instance of HP Web Jetadmin will indicate a communication failure
when HP Web Jetadmin attempts to re-establish communication. The Refresh Selection (Full) command can
be used on these devices to cause HP Web Jetadmin to reset them to SNMPv3-enabled devices.
NOTE: If SNMPv3 communication was established outside of HP Web Jetadmin, the global discovery setting
for Discover SNMPv3 Devices must be configured in Tools > Options > Device Management > Discovery >
General. No new SNMPv3 devices will be added to the database unless this option is enabled.
