Security Features Available Through the Embedded Web
These features are either only partially offered in Web Jetadmin, or are only available for
configuration through the MFPs embedded web interface.
LLMNR
Link-Local Multicast Name Resolution (LLMNR) is a protocol that provides a method for resolving
host names on the same local link. It is useful in networks that do not have a DNS server. It does
not require any configuration or administration in order to work, and it supports IPv4 and IPv6. A
host on the network that needs to resolve a host name sends a query to a multicast address. Other
hosts on the network who support LLMNR listen to this multicast address, and respond to the query.

HP Jetdirect XML Server
The HP Jetdirect XML Services setting is used to enable/disable the IXDM Access Interface (IXA).
XML Device Model (XDM) provides a method for collecting or configuring complex data where
SNMP is impractical. One such example is IPSec. Web Jetadmin 10.2 supports configuring IPSec
on a device through XDM. To configure IPSec, WJA constructs an XML document and sends it to
the IXA interface on the device. When the HP Jetdirect XML services setting is disabled, the IXA
interface is disabled and configuration through XDM cannot take place.
