4 Getting Started After installing the Workspace Server, login to NetBrain Workstation using the instructions below. A. Login: 1. Select a Workspace Server in the Server dropdown menu. 2. Login to the workstation. The default username/password is admin/admin (this can be changed in the License Server) B. Discover Live Network: 1. Launch Network Discovery from the Start Page Click the Network Settings button to enter telnet/ssh credentials and SNMP strings Enter the IP address of a seed router and then click Start Discovery. Tip: To achieve best accuracy, make sure all login credentials are specified, the network server has SNMP access to the network, and CDP/LLDP/FDP are turned on. C. Benchmark Live Network & Discover L2 Topology 3. A network benchmark is necessary to build the layer-2 network topology following a live network discovery. For a more detailed walk through of the benchmark process, watch this short tutorial. NETBRAIN OE 5.1 WORKBOOK 4

5 1. Select Benchmark Server Benchmark from the Workspace tab. This will open a browser pointing to the NetBrain Enterprise Server. 2. From the browser, click Enable Benchmark. 3. Ensure that Auto build L2 network topology is selected and click Submit. 4. The benchmark will begin and will run for several minutes. To check the status, click the Home tab. 5. Once the benchmark is complete, return to the NetBrain Client Workstation. Select Refresh Workspace from the NetBrain menu to update NetBrain with the new benchmark data. NETBRAIN OE 5.1 WORKBOOK 5

6 1. Divide Network into Sites To help visualize the hierarchy of the entire network, NetBrain allows you to easily organize your network into sites. A large network should be divided into several levels of sites (e.g. country, state, city, office). The Site Map feature includes an overview map, a site topology map, and a site pane. This section is optional and will walk you through creating network sites. Instructions: 1. To define network sites, click the Site Manager button from the Workspace tab of the Ribbon menu. Site Manager 2. Define the Site Tree by importing a spreadsheet which contains your site information. Click Import from File. Note: Most enterprises maintain these spreadsheets already. Import Site Spreadsheet 3. Complete the Level fields in the following window (Define Site Hierarchy). Note: Level # indicates the hierarchy relationship of a site (lower number = higher hierarchy level). Import File to Create Site NETBRAIN OE 5.1 WORKBOOK 6

7 4. NetBrain can populate Sites with their proper devices automatically. In the Site Manager window, click the Border Interface tab to define the criteria NetBrain will use to calculate sites dynamically. Then click Calculate. Add Neighbor Devices to Map 5. Next, click Rebuild Site to split the whole network topology into the specified sites. Finally, click Commit to submit the Site definition Layer-2 Map from IP Search 6. To map a Site, right-click the site and choose Overview Map or Topology Map. NETBRAIN OE 5.1 WORKBOOK 7

8 2. Search & Map the Network On-demand mapping can be performed in several ways within NetBrain. This section will demonstrate how to instantly create a network diagram by searching for a device and mapping its neighbors. Instructions: Watch Demo Video 7. To get started, type a hostname into the Search box under the Home tab. Tip: To minimize your search results, check the box next to Exact Match Only. Search Hostname 8. Under the Search Results tab, hover the cursor over the device and click the icon for a Layer-3 preview map. Click View Larger Map to open a new Qmap centered on the search result. Tip: To open the map full-screen, right-click the map tab and click Move to Previous Tab Group. Map Results 9. Devices displayed with a icon have neighbors not currently displayed on the map. To display the neighbors, click and then double-click a device. Tip: To select multiple neighbors simultaneously, use the CTRL key followed by ENTER. You can also double click All Neighbors to display all neighbors on the map. Identify Neighbors NETBRAIN OE 5.1 WORKBOOK 8

9 10. Repeat Step 3, extending neighbor devices, until you have a network map satisfying your area of interest. Add Neighbor Devices to Map 11. Also try searching IP address (e.g ) and Configuration snippet (e.g. EIGRP 200). Layer-2 Map from IP Search NETBRAIN OE 5.1 WORKBOOK 9

10 3. Decode Network Design You can interact with the map to access network configuration and design data. This section will demonstrate how to display detailed configuration data on the map, access live and historical device data, and annotate the map with routing design. Instructions: Watch Demo Video 1. To visualize interface configuration such as routing protocol, multicasting, ACLs, etc., simply zoom into the map (using the wheel of the mouse). Zoom In to See Configuration Details 2. The configuration data behind the map labels is accessible. Just hover the mouse cursor over a label to see a configuration snippet. Tip: To save this snippet as a note on the map, click the save icon Configlet window. on the Hover Cursor over an Interface Label 3. NetBrain s Observer feature displays detailed device properties, performance data, historical data, and more. To access this information, continue to zoom in on a specific device until the device is targeted in green brackets. NETBRAIN OE 5.1 WORKBOOK 10

11 Zoom Into a Device for Observer View 4. Continue to scroll through Observer cards with the mouse. Tip: You can interact with these cards to perform actions (e.g. create new map, launch live device monitoring, etc.). Scroll through Observer Cards 5. To visualize design criteria at-a-glance, you can instantly annotate the map with routing, multicasting, or MPLS VRF. From the map s floating menu, select Highlight then click Routing Protocol Annotate Routing Design on the Map 6. Devices and interface links will be colorcoded (with a legend) to reflect configured routing protocol. Map Color-Coded for Routing Protocol NETBRAIN OE 5.1 WORKBOOK 11

12 4. Map an Application Flow NetBrain can automatically map a path between any connected devices in the network, such as an application flow.
