Details About Running a WS-Discovery
A discovery that uses the Web Services protocol requires minimal settings to launch. HP Web Jetadmin uses
the Web Services protocol to query the network to find network-connected and PC-connected devices. After
an initial device response, HP Web Jetadmin performs additional SNMP queries to learn more about the
devices and add them to the All Devices list. This discovery mechanism finds devices on both local and
remote subnets.
Characteristics of a Web Services discovery for network devices include the following:
●
Packets contain a router hop-counter (IP time to live attribute) that can be set from within
HP Web Jetadmin. The default is 4 hops.
●
Packets expire when the router hop-counter reaches zero.
●
The discovery mechanism is fast.
●
The discovery presents low network traffic.
The reach of a Web Services discovery depends on the following:
●
The setting for the Routers to cross (hops) configuration option for the discovery (see
Configure the
General Settings for Device Discoveries on page 56).
●
The configuration of the network routers. If the router is configured to pass Web Services requests on to
other sections of the network, then a discovery might discover devices on the entire network.
You can also control the reach of discoveries by configuring the Web Services request to span a certain
number of routers (see
Configure the General Settings for Device Discoveries on page 56). The routers must
be configured to allow the Web Services request to be forwarded.
The discovery can also be affected by the configuration of the local firewall (see
Discovering Devices with
HP Web Jetadmin through Firewalls on page 124).
If the router is configured to pass Web Services requests on to other sections of the network and the
discovery is configured to cross multiple routers, then the discovery might discover devices across multiple
subnets and perhaps the entire network.
Details About Running a WS-Discovery
If you choose the WS-Discovery method while creating templates (see
Create a Discovery Template
on page 154), editing templates (see Edit a Discovery Template on page 156), or scheduling discoveries (see
Schedule a Discovery on page 151), then the Choose WS-Discovery settings page is displayed. On this page,
select the number of routers to cross (or hops) for the discovery. Increasing the number of hops might
increase the amount of time for the discovery to complete. In addition, the discovery generates more
network traffic than a discovery with fewer routers to cross.
