2. Product Tour
Powered by deep network discovery (via CLI and SNMP), NetBrain’s Adaptive Network Automation provides instant collection, visualization, and analysis of critical network data, without the need to write any scripts. Important stories live in data but network teams struggle to make sense of the vast amount of information available – from telnet/SSH, SNMP, or collected through 3rd party network management tools. Visualization is a powerful means to discover and understand these stories, and fundamental for collaboration. NetBrain Dynamic Maps provide the following key advantages over static Visio maps:
• They can be created instantly – thousands of nodes can be mapped in seconds.
• They provide full visibility of the network including L3 and L2 topology, network design and operational status.
• Recurring benchmarks can be scheduled to keep the maps always update-to-date.
• User activity is recorded for change tracking purposes.
• Any task can be embedded into the map in the form of an Executable Runbook.
• Results of analyses are embedded into the map for future reference. •
Take this Product Tour to learn about NetBrain’s powerful map-based automation and visualization capabilities.
2.1 Search and Map

2.4 Executable Runbooks
An Executable Runbook is an active flow chart. Each node of the chart corresponds to a step of a network task and can take the form
of an executable application (Qapp), a built-in function (e.g. ping or traceroute) or simply text (e.g. a note or a description). The
runbook takes the map data as input and the results are displayed on the map. Runbook analysis can be triggered via API integration
with 3rd party trouble-ticketing, monitoring or IDS/SIEM systems, when events such as slow application performance or a cyber-
attack are detected.
To learn about NetBrain’s built-in functions and runbooks for running design/configuration checks and for troubleshooting specific
technologies, such as QoS, multicast, dynamic routing (OSPF, IS-IS, BGP, EIGRP), etc. jump ahead to the Technology Labs section of
this workbook.
This section will walk you through how to use an Executable Runbook for troubleshooting common network problems.
Instructions:

4. Common Tasks & Workflows
4.1 View Device Detail and Extend Neighbors
NetBrain turns your entire network into a searchable database. You can find any device, view its details, and extend its L2 and L3
neighbors to create a map of its connections.
Instructions:
1. Search for a device: You can find a device or create a group of devices by searching for any part of a hostname, IP address, configuration file, device type, vendor, etc. Type hostname NB_BOS_HQ_CE1 into the Search box and press the Enter key.
Tip: Just type in the first few letters of the hostname and select the device from the pulldown menu.
2. The search results are organized by All (devices), Configurations, Map and Dashboard. Click into the hostname NB_BOS_HQ_CE1 to view the device detail.
NETBRAIN ITE WORKBOOK | 33
3. Device detail information such as vendor, model, software version as well as configurations, route table and CDP tables are displayed. A preview map with three of its neighbors are shown. Click Open Map link to create a new map.
Tip: You can also close the Device Detail page to return to the search results page. From the search results drag and drop a device icon to open a new map for just this device without its neighbors.
4. Extend L3 neighbors: Click the attached to a device
icon to add neighbor devices to the map. In the Neighbors window, you can view all neighbor devices or filter neighbor by the interfaces and type of topology. For example, select the interface f0/1 of the device NB_BOS_HQ_CE1 to view three devices connected to this interface. Click a neighbor device to select a neighbor and click Add to Map button to draw it. You can select multiple devices.
Tip: Double click an interface to draw all neighbor devices connected to that interface in the map. You can also double-click All Neighbors to draw all neighbors on the map.
5. Extend L2 neighbors: In the Neighbors window, select L2 Topology from the pulldown menu of the topology and add L2 neighbors to the map. For example, for the device NB_BOS_HQ_CE2, select L2 Topology and double click All Neighbors to add all its neighbors in the map.

6. Repeat the step 5 and 6 till you have all devices you are interested in on the map.
4.2 Perform Health Check on Site Map
NetBrain discovers your entire network at a rate of 2000 devices per hour with its patented neighbor-walking algorithm. You can
explore the hierarchical virtual model, organized by site, and run a health check on any site.
Instructions:
1. Open a site map: Click Site in the left menu bar and browse through the site US/Canada > United States of America > MASSACHUSETTS > BOSTON. Right click the site and select Open Site Map from the menu.
Tip: The number in parentheses next to a site is the number of devices belonging to the site. A device can only belong to a leaf site which does not have any child sites.
2. The site map of a parent site shows how its child sites are connected. Zoom in to view more connection details.
Tip: A parent site has one or more child sites. Its site map shows the connections of its child sites. The site map of a leaf site shows the connections of its network devices in addition to the connections between its network devices and neighbor sites.
