HP Web Jetadmin Software manual Perform Quick Device Discoveries, SLP Multicast Discovery

You can only use the Quick Device Discovery feature to find PC-connected devices if the devices are already in the HP Web Jetadmin database. To find a PC-connected device that is not in the database, you must run a device discovery and use the PC connected devices option. For more information about PC-connected device discoveries, see How HP Web Jetadmin Discovers PC-Connected Devices on page 126.

To find a network-connected device, the Quick Device Discovery feature searches the device addresses in the HP Web Jetadmin database. If the device address is in the database, HP Web Jetadmin highlights the device in the All Devices list. If the device address is not in the database, HP Web Jetadmin performs a network query only 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 101.

Perform Quick Device Discoveries

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. 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

●Details About Running an 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 finding 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 finds 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-specific 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 traffic.

●HP Jetdirect firmware 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:
