DCE device discovery

When you create a device discovery process, information about that process is listed in this view. Information about the device group selected during the SNMPv1 and NetBotz Appliance discovery process is not included. Wait a few minutes after a discovery process reports it is idle before you consider that it failed to discover all the devices it should have. The Data Center Expert server can take more time to list discovered devices in the Unassigned group in the Device Groups view, than it takes the discovery process to discover those devices. Discovery entries Use the Export Discovery Entries option to export information about the selected saved device discovery processes to a local file. Information about the device group selected during the SNMPv1 and NetBotz Appliance discovery process is not included. Use the Import Discovery Entries display to import saved device discoveries from a local file. Discovery entries file format Use this file format to import SNMPv1 and NetBotz Appliance device discovery entries to the Saved Discoveries view from a local *.txt file. Information about the device group selected during the discovery process is not included. Note: You cannot import device discovery entries for SNMPv3 or Modbus devices. Format for SNMPv1: SNMPv1:<IP Address or Range>:<port>:<timeout>:<retries>:<trap registration (true or false)>:<read community>:<write community> Example: SNMPv1:10.218.10-15.*:161:2:3:true:public:private Format for NetBotz Appliance: NetBotz Appliance:<IP Address or Range>:<port>:<security mode (HTTP or HTTPS_AVAIL_NO_VERIFY or HTTPS_REQ_NO_VERIFY or HTTPS_REQ_VERIFY)> Example: NetBotz Appliance:10.218.10.166:80:HTTP

To discover NetBotz 750 appliances, choose the SNMPv1 or SNMPv3 discovery type.   NetBotz 750 cameras are supported in firmware versions 5.2.x and newer only.   Only a Data Center Expert Server Administrator can configure the settings needed to discover NetBotz 750 appliances, and add SSL certificates if used.    1. Before you begin    IMPORTANT   When you log in to a NetBotz 750 device for the first time, you must log in as root via SSH or   through a serial connection and set the root password.  See the Installation and Quick Configuration Guide for the NetBotz Rack Monitor 750 and the   Security Handbook on the NetBotz 750 Rack Monitor product page.   Before you discover NetBotz 750 appliances in Data Center Expert, make sure you have: Access to the NetBotz 750 appliances you want to discover. The IP addresses or IP address range for the NetBotz 750 appliances you want to discover.   Only a Data Center Expert Server Administrator can configure Device File Transfer Settings, NetBotz Appliance Credentials, and add the NetBotz 750 SSL certificates to Data Center Expert.   2. Configure settings on the NetBotz 750 Appliance   On each NetBotz 750 Appliance you want to discover: Log in to the NetBotz 750 web client. Enable SNMPv1 or v3 in the Settings > System > SNMP option. By default, SNMP is turned off on the NetBotz 750 appliance. If Data Center Expert uses a self-signed certificate, uncheck the Verify DCE Certificate in Trust Store option in the Settings > System > DCE Surveillance option.   3. Add SSL Certificates to Data Center Expert and NetBotz 750 Appliance(s)   If Data Center Expert uses SSL to communicate, add SSL certificates to both Data Center Expert and each NetBotz 750 you want to discover.   Add the NetBotz 750 certificate to Data Center Expert   Add the certificate from each NetBotz 750 you want to discover in Data Center Expert. Otherwise, the cameras connected to the NetBotz 750 will not appear on the Surveillance tab. Note: You do not need to add the NetBotz 750 SSL certificate to DCE if you intend to select No verification in the Device > NetBotz Appliance Communication Settings > NetBotz 750 Camera Communication Settings option. This option is available after you discover the NetBotz 750.   Open a web browser and go to the NetBotz 750 web client. Download the certificate from the browser, and save the certificate file in Base-64 encoded X.509 format. Log in to the Data Center Expert client. Go to System > Server Administration Settings > Server SSL Certificates. Click Add. Paste the certificate, or, click Import Certificate and then navigate to the NetBotz 750 certificate to import it. Click Add.   Add the Data Center Expert SSL certificate to the NetBotz 750   Add the SSL certificate from Data Center Expert to each NetBotz 750 you want to discover. Otherwise, the NetBotz 750 cannot post camera clips and motion updates to Data Center Expert. Note: If Data Center Expert uses a self-signed certificate, make sure the Verify DCE Certificate in Trust Store option is unchecked on each NetBotz 750 in the Settings > System > DCE Surveillance option. You do not need to upload the Data Center Expert self signed certificate to the NetBotz 750.   Open a web browser and go to the Data Center Expert web client. Download the certificate from the browser, and save the certificate file in Base-64 encoded X.509 format. Log in to the NetBotz 750. Go to Settings > System >Trust Store. Click Add. Open the certificate file in a text editor, and copy and paste the certificate into the field. Click Add. Repeat steps 4-8 for each NetBotz 750 you want to discover.   4. Configure settings on Data Center Expert   Click Device > SNMP Device Communication Settings > Device File Transfer Settings to add the root credentials (not superuser) for at least one NetBotz 750. Choose the protocol SCP Only. This allows Data Center Expert to download the device definition file (DDF) from the appliance. Click Device > NetBotz Appliance Communication Settings > NetBotz Appliance Credentials. Click Add to specify the user credentials (not root) for the NetBotz 750 appliances you want to discover. If the credentials are different for any of NetBotz 750 appliances you want to discover, add each appliance to the list individually.   Warning and critical alarms can occur if Device File Transfer Settings and NetBotz Appliance Credentials are not configured either before you discover NetBotz 750 appliances, or, during discovery if you are a Data Center Expert Server Administrator. You can see these alarms in the Active Alarms pane in Data Center Expert.   5. Discover NetBotz 750 appliances   Click Device > Add devices. Select SNMPv1 or SNMPv3 depending on how your NetBotz 750 appliances communicate. Specify the IP address or address range, SNMP settings, and whether you want to register for Priority scanning. Add Device File Transfer Settings for at least one NetBotz 750 Appliance if you have not already done so. See step 4 above. Add NetBotz Appliance Credentials for your NetBotz 750 Appliances if you have not already done so. See step 4 above. Choose a group, and click Finish.   6. Configure NetBotz 750 Camera Communication Settings in Data Center Expert   If you have imported signed certificates from the NetBotz 750 Appliance, it is not necessary to modify the NetBotz 750 Camera Communication Settings.   If you imported a self signed certificate from the NetBotz 750 Appliance, and that certificate does not have a valid hostname:   Go to Device > NetBotz Appliance Communication Settings > NetBotz 750 Camera Communication Settings. Select one or more NetBotz 750 IP addresses, and click Edit Communication Settings. Select Verify certificate and click OK.   7. Configure Surveillance Settings in Data Center Expert   Go to Device > Surveillance Settings. Select the NetBotz 750 cameras you want to license, check the box to License Cameras, and click OK. See Surveillance Settings.

You can edit the discovery settings, the device group, and scheduling for any discovery process listed in the Saved Discoveries view. You cannot edit the type of device the process will discover. The difference in the three types of discovery processes is the type of settings used to define the process. Select Saved Discoveries view, a Device option in the Window menu, to access the Saved Discoveries View. Right-click a listed discovery process and select Edit. In the discovery settings display, edit the settings, as appropriate, and click Next, to change the scheduling or run (or both) the edited process, or Finish, to save the changes in the Saved Discoveries view without running or scheduling the process. In the "Choose Device Group" display, edit the device group, as appropriate, and click Next. In the "Discovery Scheduling" display, do one or both of the following actions, and click Finish, to add the process to the Saved Discoveries view. Use the Enable discovery scheduling option to schedule the days and times when the discovery process will be run automatically. Use the Run discovery now option to run the discovery process when you click Finish.

APC, MGE, NetBotz Appliances, and third-party devices are added to the list of devices the Data Center Expert server monitors by creating and running device discovery processes.   As devices are discovered, they are added to the All Devices and Unassigned device groups in the Device Groups view by default, or, if you have created other device groups, you can place devices into a device group you select.   There are separate discovery processes for each type of device:   SNMPv1 devices: APC or third-party devices that use basic SNMP communications SNMPv3 devices: APC or third-party devices that use secured SNMP communications NetBotz Appliances (except for the 250, 300, 303, 310, 400, 410, and 750 models. Use the SNMP discovery process for these NetBotz models.) Modbus TCP   You can run a discovery process once, rerun that process whenever you want, or schedule that process to run periodically. You initiate a discovery process by accessing the "Device Discovery" wizard in the following ways:   Select Add Devices in the Device menu. Right-click on any device in the Device View or Map View, and select Add Devices. Click the green plus sign icon ( 92307492_360038795874.png ) in the Device View. Right-click anywhere in the Saved Discovery view, and select Add. Right-click on a discovery process listed in the Saved Discovery view, and select Run, to rerun that process, or Edit, to run an edited version.   In DCE 8.2.0 and newer, Run discovery now is checked by default.

Manage the File Transfer Protocol (FTP) or Secure Copy (SCP) access values for APC SNMPv1 and SNMPv3 devices. Keep the access list up to date to comply with the latest cybersecurity requirements. See New cybersecurity requirements in NMC3 Note Functionally identical versions of this display are used by the Device > SNMP Device Communication Settings > Device File Transfer Settings option and: SNMPv1/SNMPv3 Device Discovery wizard Apply Firmware Updates wizard APC SNMP Device Configuration wizard A change saved in one display is reflected in all. To use FTP for APC SNMP device access, FTP server access must be enabled at that device. To use SCP for APC SNMP device access, Secure Shell version 2 (SSHv2) console access must be enabled at that device. Note: By default, the Data Center Expert server can download firmware via FTP only to devices that use apc (lowercase) for the username and password. The credentials used for device access are identified in the Device File Transfer Settings display.
