Table 4-18 Other protocols (continued)

Item Description

Enable Device Discovery

Select device discovery protocols supported by the print server:

SLP

If enabled, the HP Jetdirect print server sends SLP packets, which are used by system

applications for automated discovery and installation.

If disabled, SLP packets are not sent.

If SLP uses multicast protocols, you must enable multicast IPv4.

Bonjour

If enabled, Bonjour services are provided. Bonjour is typically used on for IP address and

name resolution (through UDP port 5353) where a conventional DNS server is not used.

For Bonjour operation, you must enable multicast IPv4.

Multicast IPv4

If enabled, the print server sends and receives IP version 4 multicast packets. If

disabled, other protocols that use multicast protocols (such as Bonjour and

SLP), might be disabled without notification.

WS-Discovery Microsoft Web Services Dynamic Discovery (WS Discovery) protocols on

the print server.

Naming Resolution

Indicates whether link local multicast name resolution (LLMNR) requests are responded to

over IPv4 and IPv6.

Enable Management

Protocols

Select the management protocols to use: Telnet, FTP Firmware Update, or RCFG.

Telnet and FTP are not secure protocols and device passwords can be intercepted.

RCFG, a remote IPX configuration protocol used by older management tools to configure

Novell NetWare parameters. Disabling RCFG does not affect direct mode printing using

IPX/SPX.

It is recommended that you disable Telnet, FTP firmware upgrades, and RCFG.

802.1X Authentication

(Full-featured print servers only) Use this item to configure 802.1X authentication settings on the

HP Jetdirect print server as required for client authentication on your network. You can also reset the

802.1X authentication settings to factory default values.

CAUTION: If you change the 802.1X authentication settings, you can lose your

connection. If communication with the printer/MFP device is lost, you might need to reset the print

server to a factory default state and then reinstall the device.

For most 802.1X networks, the infrastructure components (such as LAN switches) must use 802.1X

protocols to control a port's access to the network. If these ports do not allow partial or guest access,

you might need to configure the print server with your 802.1X parameters prior to connection.

To configure initial 802.1X settings before connecting to your network, use an isolated LAN, or a direct

computer connection using a cross-over cable.
