Solution

MarkVision Professional lets you search your network for devices such as printers and print servers. You can then schedule and configure discoveries to suit your needs. Once devices have been "discovered," their locations are stored on the MarkVision server. By default, they populate the All Devices folder. To discover devices, you can either:

Create a profile (or profiles) for the devices you want to discover. Instructions are provided below.
Or
Discover individual devices or small groups of devices. Click here for the instructions.

Note: If you have upgraded from a previous version of MarkVision, any devices that have previously been discovered and stored on the server are available in version 10.1 as a profile called Full Discovery.
About device profiles
Device profiles define the range of devices that you want to discover, letting you select devices specific to your current needs. You can create multiple device profiles, each with a different set of devices. Each profile can then be saved and reused for future discoveries.
A. Creating discovery profiles:

  1. On the MarkVision Home screen, go to MarkVision, Device Discovery and select Manage Discovery Profiles (or go to the All Tasks menu and select Device Discovery Profiles).

  2. Click New.

  3. Enter a name for the profile that you want to create. For example, My Network.

  4. Enter any comments you have about the profile.

  5. Click Add to add devices to the Include list. The Discovery Profile screen appears.

  6. Select the type of address concerned and enter the range from which the devices will be included. Specify one or more of the following: 


    • a. TCP/IP address, subnet, or hostname
      IP addresses should be in the dot notation form X.X.X.X  -  for example, 192.168.12.34.


      1. To perform a network discovery (i.e. search a subnet), use a zero (0) or asterisk (*) as a wildcard. For example, 192.168.0.0 would search the entire Class B network, finding all the devices whose address begins with 192.168. You can also search for a device using its hostname.

      2. After you enter the address information, you can enter SNMP community names to change the read- or write-access privileges. To change 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. For instructions on how to change the print server name, refer to your print server documentation.

      3. Click Include to add the addresses or hostname to the Devices to Include on the server box.

    • b. TCP/IP address range


      1. Enter the TCP/IP address range, beginning with the From: box and ending with the To: box, and then click Include. With this option you can also enter SNMP community names to change the read- or write-access privileges.

      2. To change 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. For instructions on how to change the print server name, refer to your print server documentation.

    • c. IPX network
      This is the network number on which your print server resides. It is an eight-digit hexadecimal number  -  for example, 000C2194.


      1. If the print server resides on the same network as your MarkVision Server, enter 00000000 (eight zeroes) 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.

      2. After you enter the address information, click Include to add the addresses to the Devices to Include on the Server box.

  7. Click OK to return to the Manage Discovery Profiles screen. The entered devices are now listed under the Include tab.

  8. Click Apply.
    Note: For instructions on discovering a device or group of devices without creating a profile, please click here.

B. Discovering devices
  1. Go to MarkVision, Device Discovery, Manage Discovery Profiles.
  2. From the Discovery Profiles screen, select the profile that encompasses the devices you want to discover.
  3. Click Start. MVP communicates with the devices included in the selected profile.
  4. To stop a discovery at any time, click Stop Discovery.

    Note:
    Performing a discovery with the Full Discovery profile, or any profile that includes all the devices on your network, requires a large amount of CPU usage. Running a full discovery can render the MarkVision Server virtually unusable while the discovery is executing.

About including and excluding devices
The Include and Exclude tabs on the Manage Discovery Profiles screen display lists of devices that are to be included in / excluded from the profile's current device list respectively. You can use these tabs as follows when creating a profile:

  1. If there are certain devices in the device range you entered that you do not want to include in the profile, select the Exclude tab and add that device to the Exclude list. Consider the following examples from the viewpoint of a network administrator:



      • If  you know the addresses of routers and computers on your network and do not want to have extraneous traffic created by the device 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 to your Include list, and then add your secretary's printer address to your Exclude list.

  2. If necessary, you can use the Remove and Remove All buttons to remove devices from the Exclude lists.

Advanced features     
To configure advanced device discovery features, click the Advanced tab from the Device Discovery main screen. The following features may be customized for an advanced device discovery profile:

  • 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.

  • 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 if 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 if network traffic is heavy. Note: 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.

Note: Discovery Profile can have its own advanced settings.

Import / Export buttons
You can use the Import and Export buttons to import or export profiles for discovery. They are saved in the industry-standard XML format.
Load / Save buttons
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. This file can be retrieved later using the Load button.
Scheduling
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.  
To schedule discoveries, do the following:
  1. Select the Schedule task from the All Tasks menu.
  2. Then select the profile you want to use for the discovery.
  3. Choose the initial day from the Start time: box, and select the time at which the discovery is to occur.
  4. You can then decide to have the discovery occur once, daily, weekly, or monthly.
  5. When you have made all your selections, click OK.
    For more information on scheduling, refer to this document: Scheduling tasks.

Naming devices
After you have found all the devices that you want to manage with MarkVision Professional, you can establish the name that MarkVision will use to identify the device. This is done using the Administrative Settings task. Note: You need administrator-level access in order to name devices or to use the Administrative Settings task. Do the following:

  1. From the All Tasks menu on the MarkVision Home screen, select Custom Names.

  2. Select the device(s) you want and enter any name you want for the device(s). For example, My Printer.

MarkVision uses a specific algorithm to determine a device's name. First, it looks to see if a name has been assigned to it from the Names of Devices task. Then it looks for the following in the order given:

TCP/IP address
hostname
IPX address
Serial number 
Property tag

You can also change the order of this list using the Administrative Settings task.
