4 1.1 Setup NetBrain Workstation 1.1 Install NetBrain Workstation Consultant Edition a) Download the software to your computer a) Run the setup file and follow the setup wizard Download the NetBrain software here. Unzip the file. For Windows 7/2008, we recommend that you right click on the setup file and select the Run as Administrator option.. c) Activate your license Launch NetBrain Workstation Consultant Edition. The Welcome to NetBrain window opens. For trial license (POC user): Click on the Activate Trial License button. Fill in your and Password in the Register for Trial License window. (The Password has been sent to you in the Proof of Concept ) For permanent license (Customer): Click on the Activate Permanent License button. Fill in your License ID, password, name, and address in the Activate License window and then click on the Activate Online button. (The license ID and password have been sent to you in the order delivery ) Note: If your license server is NOT connected to the Internet, please and we will send you instructions on how to activate the license offline. 4

5 1.2 Start Workspace Wizard Wizard Step 1: Define Telnet/SSH/SNMP credentials and proxy When you start NetBrain Workstation for the first time, the Workspace Wizard automatically starts up. For the first step, 1. Click the Telnet/SSH login tag. 2. Click the Add button. 3. Enter the corresponding values. 4. Repeat step 2 and 3 to add all possible Telnet/SSH login credentials. 5. Click the other tabs in this window to add Privilege Password, SNMP community, Network Server and Jumpbox. 6. Click the Next button to go to the next step of wizard. Note: If Workstation can access your network directly, then you do NOT need set a Jumpbox. Otherwise you do need set a Jumpbox so that the Workstation can access the live network. 5

6 1.2 Start Workspace Wizard Wizard Step 2: Discover your network from a seed router 1. Click the Telnet and SNMP field and select how system accesses your live network from the drop down menu. If you are not sure, select Telnet/SSH and SNMP safely. 2. Enter the IP address of a seed router. 3. Click the Start Discovery button. 4. Select an entry to view the log. 5. View the discovery statistics and summary here. Note: This discovery process includes two steps: discover the network devices and retrieves the live data from your live network; build L3/L2 topology. Depending on your live network, the time for each step varies, from a few minutes to 20 minutes. 6. Click the Finish button to exit the Wizard. Note: The discovery statistics are updated and displayed at. If you fail to discover some devices in your network, first make sure that you enter all possible live network settings at step 1 Define Telnet/SSH/SNMP Credentials and Proxies and then you can try different seed routers. 6

7 1.3 Tune Discovery Results a) Rediscover unknown IP 1. Go to the Workspace menu tab, click on the Manager icon. 2. Select Unknown IP at the left pane and then Username/Password Mismatch. At the right pane, the system lists all IP addresses discovered as the neighbor IP address in the discovery process but was not accessible due to the fact that none of the defined username/password pairs worked. 3. Click the Rediscover button at the top right. Add the username/password pairs at the Live Network Settings window. 4. Close the Live Network Settings window and click the Start Discovery button in the Live Network Discovery window. Note: Using a similar approach, you can also resolve unknown IPs due to Privilege Password Mismatch or others. b) Rediscover devices that were discovered only by SNMP 1. Go to the Workspace menu tab, click on the Manager icon. 2. Select Discovered by SNMP at the left pane. At the right pane the system lists all devices discovered by SNMP but not accessible by Telnet/SSH. 3. Right click a device and select Live Access Log menu to view why the system could not telnet/ssh to the device. If the Telnet/SSH login credentials were missing, click Workspace menu tag from the menu bar and then the Settings icon for Live Network Settings to add the credentials. 4. Select one or multiple devices (press the Shift or Ctrl key to select multiple devices) and from the right click menu select Discover Selected Devices. 7
