for network-connected devices. If the device address is found on the network, HP Web Jetadmin adds the device

to the database and highlights the device in the All Devices list.

The Quick Device Discovery feature does not search the device lists. For instructions on searching the visible

columns in device lists, see Search Device Lists on page 114.

To perform a Quick Device Discovery, perform the following steps:

1. In the Device Management navigation pane, enter the IP address or hostname for the device in the Quick

Device Discovery box, and then click the Go button.

2. If the device is not found, perform the following steps:

a. Click the Credentials may be required to locate the device link.

b. On the Enter Credentials window, select the Use checkbox, enter the SNMPv1 Get Community Name

for the device, and then click the OK button.

c. If the device is found, continue with step 3.

-or-

If the device is not found, click the Cancel button, and then click the OK button on the Quick Device

Discovery window. Verify that the device is connected to the network, verify the device address and

credentials, and then repeat the Quick Device Discovery.

3. On the Quick Device Discovery window, click the OK button.

SLP Multicast Discovery

(For network device discoveries only.)

A discovery using SLP multicast requires minimal settings to launch. SLP (service location protocol) is used to

cast a query onto the network for the purpose of nding HP Jetdirect devices. After initial device response, SNMP

follow-up queries are performed to learn more about devices and add them to the All Device list in

HP Web Jetadmin. This discovery mechanism nds HP Jetdirect devices on both local and remote subnets.

Characteristics of an SLP Multicast discovery for network devices include:

●

Multicast packets are sent to the HP Jetdirect-specic multicast address: 224.0.1.60.

●

Packets contain a router hop-counter (IP time to live attribute) that can be set from within

HP Web Jetadmin (default 4 hops).

●

Packets expire when router hop-counter reaches zero.

●

The discovery mechanism is fast.

●

The discovery presents low network trac.

●

HP Jetdirect rmware must be at least x.06.00 or greater.

●

Only HP Jetdirect-connected printers will be discovered.

The reach of SLP multicast discovery will depend upon the:

●

Setting for Routers to cross (hops) (a conguration option for Discovery; see Congure the General Settings

for Device Discoveries on page 64).

●

Conguration of the network routers; if the router is congured to pass multicast requests on to other

sections of your network, then a discovery could potentially discover devices on your entire network.
