Selecting a Script Filter

If you would like to further refine a device discovery script, you can add one of two Script Filters: one which restricts the discovery to Cabletron devices, and one which restricts it to devices which respond to an SNMP query.

1.Click on the Script Filters drop-down menu; the three available filters will be displayed, as illustrated in Figure 3-9.

2.Click to select the appropriate filter:

All Devices — the script will discover and add to the central node database all devices in the specified subnet(s) or IP address range(s) that respond to either an SNMP or a PING query. This is the default value.

SNMP only devices — the script will discover and add to the central node database only those devices in the specified subnet(s) or IP address range(s) that respond to an SNMP query. Selecting this filter eliminates the discovery of “Ping” devices.

Cabletron only devices — the script will discover and add to the central node database only those devices in the specified subnet(s) or IP address range(s) that respond to an SNMP query and are identified as Cabletron devices. Selecting this filter eliminates the discovery of third-party devices.

3.Define your remaining Discover script parameters as explained in the previous sections, or click OK to save your selection and return to the Discover Manager window.
