SNMPv3 authentication and encryption has three levels of support:
• No authentication and no encryption
• Authentication with no encryption
• Authentication and encryption
Note: The selected level serves as a minimum level of protection. The MFP negotiates
with the SNMPv3 requestor, and a higher level of protection may be agreed upon
and used by both.

Supporting IPSec (Internet Protocol Security)
IP Security protocol provides authentication and encryption of communications at the network layer
allowing all application and network communications over the IP protocol to be secure. IPSec can be
set up between the MFP and up to five hosts, using both IPv4 and IPv6. To configure IPSec through
the EWS:
1
Open a Web browser. In the address line, enter the IP address of the MFP being configured
using the format: http://ip_address/.
2
Click Configuration.
3
Under Other Settings, click Network/Ports.
4
Click IPSec.
Two types of authentication are supported for IPSec:
• Shared Key Authentication—Any ASCII phrase shared among all the participating hosts.
This is the easiest way to configure when only a few hosts on the network use IPSec.
