2 Install and Launch NetBrain Workstation The administrator should have already set up the shared workspace and the shared data is stored in Enterprise Server. The end-user logs in to the server and the workspace data will be automatically downloaded to the workstation from the server. The workstation is used for documentation, troubleshooting, and design. 1. Download and install the workstation software 2. Setup the NetBrain server address Enter or domain name of your Gateway Server>/netbrain in your web browser and select Install Workstation. Launch Workstation and select Change Server option from the Login window. 3. Enter username and password Ask your administrator for the username and password. The default username/password is admin/admin. 4. The system will automatically download the shared workspace data from the server

3 Common Workflow All-in-one Search Mapping Analyze From Map Search NetBrain workspace, database and Visio maps on your PC using: IP address or device hostname Text inside maps Configuration keywords Model, serial number, MAC, etc. From the search results, Create a dynamic Qmap (L3 and L2) instantly View the relevant Visio diagrams Directly from the map, Visualize the network design Monitor Analyze configurations and routing Compare historical data 1. Search Enter a keyword such as IP address, configuration keyword or model in the Search box and press the Enter key. Tip: check the Exact Match Only option or put double quotes around the keyword for exact matching. 2. Map the search results 3. Analyze from the map Mouse over a search result such as an end system. Select L3 Page or L2 Page and click on the map to create a dynamic Q-map. Click on the blank space, a device or a path on the map and select the various operations from the map floating menu.

4 Introduction Dynamic Documentation Dynamic Documentation NetBrain s dynamic network mapping capability allows you to instantly visualize any aspect of your network. Dynamic maps are data-driven and contain rich details such as IP addresses, subnet masks, routing protocols, multicast groups, and access-lists. This means that you can zero in on a problem area and start working with an interactive network map in seconds. NetBrain can instantly index and search your network for the information you want. Search for IP address, hostname, inventory data (e.g. serial #), or any keyword, and create a map instantly from the search results. L3 and L2 devices can be grouped in many different ways to help you manage your network easier using dynamic device groups, link groups, sites, or switch groups. The Map Center is a central repository to share Qmaps and Visio maps among team members. Maps can be scheduled to be automatically updated. In addition to maps, you can create asset reports and Word documents instantly with NetBrain. 4
