NetBrain Overview


NetBrain Overview

o Traditionally, users interact with multiple device interfaces

o With NetBrain:

» Users build a dynamic network map first

» Interface with the devices through Apps

o Improves efficiency through automation

o Acts as an operating system, letting users view and manage network devices without direct CLI access


Interact with your network through a Qmap

Discovery Overview


Shared Network Settings

o Username/password pairs and enable passwords are used to Telnet/SSH to devices and retrieve live data.

o SNMP RO strings are used to access devices via SNMP. Monitoring and discovering devices require SNMP RO strings.

o NetBrain also supports Telnet/SSH to network devices via a Jumpbox.

Shared credentials do not allow users to modify device configurations


Live Network Discovery

o Discover your Live Network from a seed device. NetBrain’s neighbor-walking algorithm discovers neighbor devices from routing and CDP/LLDP tables

o The system retrieves device info by SNMP and collects data such as configurations and routing table via CLI show commands

Automating Documentation


Create a Qmap using Visual Search

o Search a hostname and create a Qmap for the found device

o Extend L3 neighbors

» By Interface, Protocol, Multicast mode, etc.


Zoom and Hover for More Detail

o Moving the mouse’s scroll wheel forward (or adjusting zoom level in ribbon) reveals additional data points

o Hovering over a data point reveals embedded data – relevant parts of device’s config file


Zoom All the Way in for Observer Mode


o Based on the NetBrain’s data-model of the network, neighbors can be extended using context-sensitive data

» Layer 2

» Layer 3

Extend Neighbors based on Model Data


Annotate Configurations

o In a Dynamic Qmap, the data points on devices and interfaces contain embedded data

» The entire embedded data, or selected portions thereof, can be annotated to the Qmap

» Select the text you want and press the button for partial data

» Pasted text is fully editable; doing so will NOT change the device’s actual configuration


Annotate Additional Info with Instant Qapp

o Drag and Drop information to the Qmap to visualize additional information quickly

» E.g. Interface MTU, OSPF cost, TE Cost, etc.


o Multiple built-in functions to improve visibility and understanding of network configuration

» Building custom Layer 3 annotations is covered in the Power User classes

Annotate the Qmap with Built-in Layer 3 Functions


Annotate the Qmap with Built-in Layer 2 Functions

o Multiple built-in functions to improve visibility and understanding of network configuration

» Building custom Layer 2 annotations is covered in the Power User classes


Using Built-in Qapps

o Select Design > Run Qapp from the Floating Menu to automate technology-specific attributes

» A Qapp is an application that collects data, analyzes, and visualizes it in one of many ways


Export to MS Visio

o All Qmap details can be exported into Visio diagrams

» Updates can be scheduled and timestamped

Let’s see it in Action!Live Demonstration


Exercise 1: Search and Create L3/L2 Maps

A. Qmap L3 connections and analyze L3 design for hostname PE-ASR1K-01

1. Qmap the device with hostname PE-ASR1K-01. (Hint: Visual Search)

2. Extend all L3 neighbors of device PE-ASR1K-01. (Hint: red plus sign)

3. View the routing protocol configured on interface g0/0/5 of PE-ASR1K-01 and annotate its configurations on Qmap. (Hint: zoom hover data click icon to Display on Current Map)

4. View detailed properties of the device PE-ASR1K-01 via Observer Mode. (Hint: hover device zoom in green brackets Observer Mode)

5. Add the ISIS L2_hello variable to the Qmap using Instant Qapp (Hint: click the Instant Qapp button and search for “l2_hello”)

B. Qmap L2 connections and analyze L2 design for IP address 10.88.1.11

1. Search and Qmap L2 device. (Hint: select L2 Neighbor in the preview dropdown )

2. Extend all switch neighbors of device Bos-Core-6500.

3. Auto-link the Qmap. (Hint: right-click Qmap Auto Link)

4. Auto-layout the map. (Hint: right-click Qmap Auto Layout, up/down arrow for device allocation Layout Style OK)

5. Annotate the switch port g1/4/11 configurationof Bos-Core-6500

6. View the Spanning Tree blocked ports for devices on the Qmap (Hint: Design STP Blocked Ports)

Automating Troubleshooting


Qmap an Application Path

o Discover and Qmap the application path between two end-points from Layer 2 to Layer 4


Probe the Qmapped Devices for Performance Issues

o The Overall Health Monitor uses SNMP to create a heat map of the top 5 performance issues


Probe for Additional Info with Instant Qapp

o Drag-and-Drop information to the Qmap to gather additional information quickly

» Initiate Monitoring and set alerts as required


Instant Qapp – Samples and Details

o Instant Qapp Samples

» Provide a sample output to assist with recognizing the correct command outputs

o Instant Qapp Details

» Each NetBrain created parser has a variable description to assist users with “what” the data means


Expand Map to Include Layer 2 Devices

o From the path results, you can select the path and change the Path Type to L2 Path to map drill down into a Layer 2 path trace

» Results will appear on a new page in the same .qmap file


Map-wide CLI execution

o Allows CLI commands to be bulk-executed across all Qmapped devices (can be launched from a Runbook)

» Output is sorted by device and can be formatted/commented directly inside Outputs Browser


Compare Historical Data

o Qmap-wide and device-specific comparison (Can launch from inside a Runbook)

» Compare Historical Data: Between any two datafolders


Using Built-in Monitor Qapps

o Select Monitor Monitor Qapps from the Floating Menu to automate technology-specific attributes

» A Qapp is an application that collects data, analyzes, and visualizes it in multiple ways


Runbooks Overview

o Runbooks allow users to group NetBrain functions into repeatable and shareable processes

» Data collection and results are stored within the Qmap

» Point and click creation

» Descriptions of the desired results and how-to can be included to guide users


Runbook Usage

o Status of each step is tracked in the Runbook

» Recall results using hyperlinks

» Multiple Executions tracked individually

» Personalized notes for each result and overall summary comments

o Multiple Runbooks can be launched on each Qmap

» Recall other Runbooks via Floating Menu
