Using the Device Discovery task

Search your network for printers and print servers with the Device Discovery task. Once devices are "discovered," they are stored in MarkVision's memory, and, by default, populate the All Devices folder. You can also schedule and configure discoveries to suit your needs.

To access the Device Discovery task, select it from the All Tasks list, or click Actions Device Discovery.

Specify one or more of the following:

TCP/IP address, subnet, or hostname

IP addresses should be in the dot notation form of X.X.X.X, for example, 192.168.12.34. To perform a network discovery (search a subnet), use a 0 (zero) or asterisk (*) as a wildcard. For example, 192.168.0.0 would search the entire Class B network, finding all devices whose address begins with 192.168.
You can also search for a device using its hostname. After you enter the address information, click Include to add the addresses or hostname to the Devices to Include on the Server box.
TCP/IP address range

Enter the TCP/IP address range beginning with the From: box and ending with the To: box. Then click Include.
IPX network

This is the network number on which your print server resides. It is an eight digit hexadecimal number; for example, 000C2194. If the print server resides on the same network as your MarkVision server, enter "00000000" (zeros) for the network number. If you do not know the network number of your print server, you can find it on the print server setup page, under the NetWare settings. After you enter the address information, click Include to add the addresses to the Devices to Include on the Server box.

To discover all devices in the Devices to Include on the Server box, click Full Discovery. To stop a discovery at any time, click Stop Discovery.

Excluding devices

To specify addresses that you do not want MarkVision to manage, click the Exclude Devices from the Server button, then enter the address or address range and click Exclude. MarkVision does not attempt to establish contact with these devices.

Examples

If you are the network administrator and know the addresses of routers and computers on your network and do not want to have extraneous traffic created by the discovery, add the addresses of your routers and computers to the exclude list.

If you want to manage all printers on the 70 subnet except for the secretary's printer, add the 70 subnet in your include list and add your secretary's printer address in your exclude list.

SNMP community names

To change the read-or write-access privileges from the default value ("public"), enter the new community names in the appropriate field. The community names are case-sensitive.

Note: This changes the MarkVision community name, not the print server community name. To change the print server name, see your print server documentation.

Load / Save buttons

You can use the Load and Save buttons to import or export a list of network addresses for discovery. The Save button saves the information in the Devices to include on the Server and Devices to Exclude from the Server fields as a text file, which can later be retrieved using the Load button.

Scheduling

To schedule discoveries, click Schedule from the Device Discovery main window.

You can schedule device discoveries to occur on a daily, weekly, or monthly basis. This ensures that the list of devices MarkVision Professional manages is always current. If your device discoveries are network intensive, you can schedule them to occur at off hours, when network traffic is at a minimum. Choose the initial day from the Start time: box and select the time at which the discovery is to occur, then choose to have the discovery occur once, daily, weekly, or monthly, and click OK.

Advanced features

To configure advanced features of device discovery, click the Advanced tab from the Device Discovery main window.

Query each address: MarkVision Professional sends an individual query to each address specified in the device discovery.

SLP Multicast: MarkVision Professional sends a single SLP request over the network. An SLP Multicast only generates a brief spike in network traffic, and discovers only Lexmark devices.

Always listen for SLP announcements from devices: MarkVision Professional listens for SLP announcements from new devices on the network. Network traffic only occurs when a Lexmark print server is placed on the network.

Also search for other vendors' devices: MarkVision Professional discovers non-Lexmark devices on the network.

Maximum number of seconds to wait for a device to respond: This specifies the maximum amount of time to wait for a device response during device discovery. Adjust this value if devices are not responding or network traffic is heavy.

Maximum number of seconds to wait for responses to an SLP Multicast: This specifies the maximum amount of time to wait for a print server response during an SLP Multicast. Adjust this value if print servers are not responding or network traffic is heavy. Only supported print servers are discovered during an SLP Multicast.

Number of retries to perform when a device does not respond: This specifies the number of attempted retries before an address is ignored. Setting this value beyond 1 does not normally provide greater accuracy. Setting this value to zero (0) disables retries, which may substantially increase speed with little impact on accuracy.
