The next step is to configure secure communications between HP Web Jetadmin and the MFPs:
Configuring SNMPv3
SNMPv3 provides encryption for communication between Web Jetadmin and MFPs. It helps to
ensure that only authorized and authenticated administrators have access to the configuration
settings of the MFPs. It also helps to ensure that no one can gather sensitive information, such as
passwords, usernames, and other codes, over the network while you are configuring the MFPs.
Note:
It is best to configure SNMPv3 by itself to ensure that the settings save
properly.
Follow these steps:
Click Security in the Configuration Categories menu (Figure 19) to view the options for
configuration. From the Security Options select SNMP Version Access Control.
