3.If desired, remove any ranges by highlighting it and clicking Remove.

4.Select the recursion level:

●Current level: discoveries check the container specified by the path and the contents of any containers in the path.

●All levels: discoveries check the container specified by the path plus the contents of all containers and sub-containers in the path.

5.Specify the print queue filter to use in Filter.

Passive SLP Discovery

(For network device discoveries only.)

When HP Jetdirect-connected devices are power-cycled, they propagate SLP (service location protocol) multicast packets. When HP Web Jetadmin detects an HP Jetdirect SLP multicast (recognized by the source 124.0.1.60), it performs follow-up SNMP queries and adds the device to the All Devices list.

Characteristics of Passive SLP discoveries for network devices include:

●Passive SLP discovery is quiet; HP Web Jetadmin does not propagate traffic unless a previously undetected device announces itself.

●HP Web Jetadmin listens for UDP traffic on port 427.

●Devices, including new devices, are discovered as they are powered on.

●Router filtering may inhibit multicast packets.

●Can be disabled on HP Jetdirect print servers.

●Will only discover HP Jetdirect-connected print servers.

Domain Discovery

●Details About Running a Discovery Using Domains (For PC-Connected device discoveries only.)

For Domain discoveries for PC-Connected devices, the domain is browsed to identify Windows hosts on the network. Each host identified is queried using the SNMP or WMI protocol. Administrative credentials are required for WMI. For WMI, once a connection is established the host is queried for a locally connected printer.

Characteristics of domain discoveries for PC-Connected devices include:

●SNMP queries are attempted on discovered nodes.

●If no SNMP Proxy Agent response, WMI queries are performed when credentials exist in settings.

●Might be slow on large domains.

●Local administrator credentials are needed to perform this discovery.

Details About Running a Discovery Using Domains

Start here if one of the discovery methods you choose is Domain (while creating templates (Create a Discovery Template on page 154), editing templates (Edit a Discovery Template on page 156), or scheduling (Schedule a Discovery on page 151)), then the Select domains page is displayed. On this page, you can select the domains to include in the discoveries:
