IP Broadcast Discoveries for PC-Connected Devices
IP broadcast discoveries for PC-Connected devices send an SNMP query to the IP broadcast address specied. An
all 1s broadcast is the default. Systems with the SNMP Proxy Agent rst answer with the operating system.
HP Web Jetadmin follows up with queries to both host and to printer specic objects. IP Broadcast discovery
does not attempt WMI queries when no SNMP proxy agent exists.
Characteristics of IP broadcast discoveries for PC-Connected devices include:
Settings are the same as network device.
SNMP queries are attempted on discovered nodes.
If no SNMP Proxy Agent response, WMI queries are performed when credentials exist in settings.
NOTE: Legacy editions of Microsoft Windows Server that have HP SNMP Proxy Agent or HP WS Pro Proxy Agent
do not always respond to IP broadcasts from the HP Web Jetadmin server. HP recommends that you use
alternate discovery methods to nd PC-connected devices on legacy editions of Microsoft Windows Server.
Details About Running an IP Broadcast Discovery
1. In the left navigation pane, click Discovery and then click Discover devices on my network (in the Discovery -
Current Tasks task module). The Device Discovery wizard is started with the Specify discovery options page
displayed.
2. Select Specify settings and then select IP broadcast. Click Next. The Select IP broadcast address page is
displayed.
3. You can:
Select a broadcast address.
Add: Add a broadcast. Type the address in Address and type a description (if desired) in Description.
Then click Add.
Show favorites only: View only the broadcast addresses you have added by clicking Show favorites
only (at the bottom of the page).
Remove: Remove addresses from the list by highlighting the address and clicking Remove.
Customize: Add or remove addresses to favorites by clicking Customize. Then select an address and
click Add Favorite or Remove Favorite. When done, click OK (Customizing IP Ranges for Discoveries
on page 146).
4. Click Next.
IP Range Discovery
In contrast to running a broadcast discovery (where all devices or HP Web Jetadmin installations in the subnet
are queried), you can choose to discover a specied IP range or a number of IP ranges. This reduces network
trac and eliminates the possibility of having unwanted devices. HP Web Jetadmin installations show up in the
database. IP Range discovery searches for devices or HP Web Jetadmin installations within a range of IP
addresses. This type of discovery is accurate and thorough but can be slow for large ranges.
