After a filter is set up, HPOV will not discover devices unless they are defined by the filter. Edit the
filter each time a new device is added to the network.
For more information about discovery filters, go to http://www.openview.hp.com
The filter file is located in the /etc/opt/OV/share/conf/C directory. A sample file is shown in the
following step-by-step example. The file has been manually edited and abbreviated to include a specific
node list and filter list for this case study:
Node list—A list of specific devices. In the example, the list is called TheNetNodes. There are two
devices in the list: AS5800-1 and AS5800-2.
Filter list—A list of attributes for the specified devices. In the example, the list is called
TheNetFilters, which specifies the filtering attributes for the devices in the node list. For example,
all devices must be SNMP compliant and Cisco devices.

To set up and edit a discovery filter, follow these steps:
Find the filters file on your Unix workstation:
aurora:/etc/opt/OV/share/conf/C ->ls
filters
oid_to_sym
Edit the filters file by using a text editor to include a node list and a filter list for your network
environment:
aurora:/etc/opt/OV/share/conf/C ->vi filters
