Configuring Device Filters
Device filters allow you to filter device group maps so that only the network information you want is displayed. You can customize the filter to display information about:
- All of your devices, including endpoint devices, such as servers and workstations.
- Only your network devices.
- Only those devices that have SNMP credentials.
You can create filters for categories of devices, individual IP addresses, IP ranges, subnets, VLANs, or combinations of these elements.
Creating a Device Filter
The following procedures provide instructions on how to create device filters using the Edit Device Filters dialog.
To create or edit a device filter:
- Select the range of devices you want to include in the filter from the list. This option sets the device range by restricting the devices filtered to one of the following groups of devices:
- . Select this option if you want the filter to be applied to all of the devices in the current discovery file.
- . Select this option if you want the filter to be applied to devices that are used to create the network, such as routers and switches.
- . Select this option if you want the filter to be applied only to those devices with an SNMP credential in the credential library.
- . Select this option if you want the filter to be applied to all discovered server devices.
- . Select this option if you want the filter to be applied to all discovered virtual machines.
- . Select this option if you want the filter to be applied to all discovered virtual server devices.
- . Select this option if you want the filter to be applied to all discovered LAN controller devices.
- . Select this option if you want the filter to be applied to all discovered wireless APs.
- . Select this option if you want the filter to be applied to all discovered wireless AP clients.
- . Select this option if you want the filter to be applied to all discovered workstation devices.
- Use the options in the section to select specific hosts or VLANs to include in the filter.
The Advanced filtering options filter for individual or ranges of IP addresses, host names, NetBIOS names, subnets, or VLANs. The following buttons call dialogs to enter values for the advanced filtering criteria:
- Click to restrict the filter to specific hostnames, IP addresses, IP address ranges or subnets. The Device Filter - Host/IP Address Include Scope dialog appears.
Enter the hosts, IP addresses, and subnets you want to include in your filter:
- . Enter the hostname, system name or NetBIOS name of the device or devices you want the filter to select. When you list a name in this box, the filter will return only those devices with that name in the box. You can use a * character as a wildcard in this box. Click to clear the box.
- . Enter the IP address, IP address range or subnet address (CIDR format) of the device or devices you want the filter to select. When you list one or more addresses or and address range for this option, the filter will return only those devices that match or fall within the indicated address range. Click to clear the option.
- Click to specify the the VLANs and indexes to include in the filter. The Device Filter - VLANs dialog appears.
Enter the VLAN name or index from which you want the filter to select devices. Click to clear the VLAN names or indexes.
- Also in the section of the dialog, select the categories of devices you want to include in your device filter.
If you select any category, only devices that match that category appears. If you have not selected any devices, all devices that meet the other filter criteria appears.
Click inside the box in the column heading to select all of the categories. When all categories are selected, all devices are returned.
- Click to save changes.
