Explanation

General

SLP listen:

Select this option to use passive discovery on port 427 for SLP signals

propagated at HP Jetdirect power-on. The default for this field is Off or

unselected.

Listen for

new

devices

Checkbox enables the passive discovery mechanism that listens on port 427

for SLP signals propagated at HP Jetdirect power-on. Default is “off”

(unchecked).

Discover

SNMPv3

Select this option to enable SNMPv3 credential entry fields in

HP Web Jetadmin discovery settings. When these credentials are added for

discovery settings or global credentials, HP Web Jetadmin attempts SNMPv3

queries on devices. The default for this field is Off or unselected.

NOTE SNMPv3 discoveries can be slow if not properly set. These should be

targeted only at parts of the network that are known to have

SNMPv3-enabled devices. Also, SNMPv3 devices require that

SNMPv3 credentials are entered.

WS-

Discovery

listen:

Select this option to use passive discovery on port 3702 for WS-Discovery

signals propagated at HP Jetdirect power-on. The default for this field is Off

or unselected.

Blocked

Devices

The Blocked Devices list contains device addresses for which device

discoveries are blocked. Devices are populated into this list in one of two

ways. First, the device can be deleted from the All Device list with the Delete

and Block option which adds the device to the Blocked Devices list. Second,

devices can be added to (or removed from) the list in Tools > Options >

Devices Lists > Blocked Devices. The device’s presence in the Blocked Devices

list prevents HP Web Jetadmin from discovering it. Adding a device to the list

through the Tools > Options > Device Lists > Blocked Devices interface does

not cause it to be removed from the All Devices list.

Other related network settings

The menu under Tools > Options > Application Management > Network contains most of the other

settings that affect discovery.
