Automated Analysis and Guided Troubleshooting Makes Anyone an Expert Problem-Solver
Instant Visibility with Network Health Checks
Every day, your business depends on a reliable, secure and fast network. Already
stretched IT resources are being asked to do more with less and network
maintenance and optimization are often overlooked. The results are unhealthy
networks improperly utilized, misconfigured and vulnerable to cyber threats.
Immediately upon connecting to the network, XG proceeds to discover all of the
subnets, devices and their interconnections within its discovery range. Path Analysis
automatically initiates, determining the hop-by-hop layer 2 and 3 path from the
analyzer to the Internet (defaults to www.google.com, but can be user-defined as any
device or site, inside or outside your network). Network Services Health shows
accessibility and responsiveness of DHCP, DNS and default routing services. The
Top Interface Health panel identifies and measures the switch and router interfaces
with the highest utilization, most discards, and most errors.
OptiView searches through your switch and router infrastructure to proactively look
for these and other problems such as high memory/CPU utilization, device reboots,
and FHRP state changes. Once detected, OptiView can notify staff via SNMP trap,
syslog message, or push notifications to your Apple or Android device (see HeadsUp
XG mobile notification app.)
Network Health
Interface Health
The Interface Health screen identifies and measures the switch and router interfaces
with the highest utilization, most discards, and most errors, as well all interfaces with
problems across your network or site. Easily sortable by various metrics, this gives
the network engineer instant visibility of the worst interfaces in the network by
utilization, errors, discards or other problems – this can serve as a daily "action list"
for network operations teams.
Interface Health
Virtualization Health
Along with the benefits of virtualization comes the complexity of managing the
virtualized network. OptiView XG has built-in capability to analyze virtual machines
and their host VMware ESX servers. This gives you the capability to quickly track
virtual server health and ensure your mission-critical applications never fail. OptiView
XG's discovery allows users to find and analyze new virtual machines that are added
to ESX host servers.
Quickly check the health of your VMware ESX Server by monitoring CPU, memory
utilization, number of virtual machines configured and running, and much more. View
VM name, guest OS, VM state, and detailed virtual machine health statistics
including processor, memory, and network usage.

Granular Data for Proactive Analysis
Get granular, real-time data into network performance statistics and errors – essential for
troubleshooting intermittent and past problems and determining if traffic bursts are the cause of
performance problems. This granular data can be gathered proactively and stored for 24 hours so that
you can go 'back in time' to analyze what was happening when the problem surfaced.
Granular Data to Troubleshoot Intermittent Problems
Automated Problem Detection
OptiView XG automatically scans for errors in the network infrastructure. Errors
are collected in a Problem Log that can be categorized and sorted. Examples of
problems detected are: performance problems, duplicate IP addresses, incorrect
subnet masks, default router not responding and many more.
Alerts on detected problems can be delivered to a network management system
via SNMP trap or syslog messages. With the HeadsUp™ XG App for Apple iOS
or Android devices, problem alerts can be sent directly to your phone or tablet,
allowing you to see and drill into problems from wherever you are. See Overview
and General Information key use case for more details.
Problem Log and Guided Troubleshooting
HeadsUp XG app for iOS and Android
Guided Troubleshooting
There are a lot of different errors and problems that occur on your network and not having the probable cause and resolution readily available increases the time required
to solve problems. The built-in Guided Troubleshooting reduces the time required to identify the root cause and fix the issue, increasing staff efficiency. Clicking on any
problem in the problem log immediately shows you the probable cause, potential impacts, and possible solutions for the problem.

Graphical User Interface Elements Speed Troubleshooting
Instantly "Prove It's Not the Network"
The 1-Click NetTest executes a series of tests to quickly prove it is not a network problem. Using
ping, layer 2 and 3 path analysis, the 1-Click NetTest verifies connectivity and determines the switchto-switch and router-to-router path to the target device. All interfaces and infrastructure devices along
the path are analyzed and problems clearly indicated. Automatic analysis of the target device reveals
configuration and resource issues. With another click, the user can document all those results
With one additional click, 1-Click NetTest is instantly added to the Application Infrastructure Test suite
for continuous monitoring of that path and end device, or launch into the detailed Graphical Path
Analysis for in-depth information.
1-Click NetTest
Quickly "Get the Picture" and start troubleshooting
Finding the path between a user and networked resources is the first step in
troubleshooting a network infrastructure performance problem. Understanding the
infrastructure involved in traffic flows, how it is performing, and where to drill down
for additional analysis provide the next steps needed to isolate issues.
XG's unique Graphical Path Analysis (GPA) provides a pictorial view of the path
between a user and other resources (local, remote, or cloud-based) and visually
indicates health data or problems on critical links and devices along the path. GPA
shows every hop at layers 2 and 3 and examines the health of every link, interface
and device in the path selected. Clicking on any port instantly shows the interface
health for the port traversed, speeding access to detailed problem information. This
is how XG "brings the problems to you" instead of you having to search for them.
The displayed results include the DNS name and IP address, the inter-switch
connections by port number, together with link speed and VLAN information. Once
launched, Path Analysis will trend interface utilization and show in/out traffic in clear
trend charts. Clicking on any device allows you to drill into specific performance
information for that device. Document the path with one-click report generation.

Automated network mapping
The faster engineers can "see" what is going on in their network, to know who is on
the network and where they are connected, and what the path is from "here to there",
the faster they can get to root cause when troubleshooting network issues. This is
especially true for maintenance organizations or system integrators who often
troubleshoot an "unknown" network. The problem is that traditional methods (CLI or
element managers) take too long and present complex data that's often hard to
interpret and difficult to correlate.
Using OptiView's patented discovery engine, users can now interact with the network
in a flexible map-based user interface to quickly visually identify configuration and
topology issues, speeding troubleshooting.
Documentation is an essential step for any project, such as pre-deployment network
assessments and new technology rollouts, but it can take too much time to complete.
From the graphical map-based user interface, one click sends the map data through
a Visio file generator, creating instant, professional network documentation. Ideal for
enterprises or service organizations, OptiView XG's mapping function saves hours of
manual labor, allowing documentation to keep up as the network changes, or provide
instant maps for client projects.
Map-based Discovery user interface
Automated Visio map generation
5 of 9
OptiView XG uses data from wireless LAN controllers (WLCs) to create wireless
network connectivity maps. The content of the map can be filtered by selecting one
or more SSIDs, desired WLAN frequency bands, device and security types. Map
details are user configurable, including link rates, channels used, AP mode and
capacity, client count by AP, and more. Wired infrastructure connections show the
entire network – from end-to-end – so you are never without updated documentation
of your wired and wireless network.
OptiView XG also provides visibility of unmanaged, unknown devices – including
WLAN access points. View these potential 'rogue' devices in both the discovery list
and see them in a network map, along with the devices connected to them.
Secondly, mapping of VoIP phone endpoints provides complete documentation for
Unified Communications deployment projects.

Network Navigator – A Window into the Network
OptiView XG's Network Navigator uses Link Layer Discovery Protocol data (LLDP,
and CDP for Cisco switches) to generate a simple diagram of a switch's "network
neighborhood". In/out interface IDs are shown along with device names. If OptiView
XG detects any problems, they are indicated on the device.
The engineer simply clicks through the diagram to navigate the devices and paths to
see whether any problems exist in a particular network area, showing exactly where
further analysis is needed. The diagram can instantly be saved as a PDF or HTML
formatted report.
Network Navigator, maps and Path Analysis are there to help you visualize your
network, to see how it is performing and where to drill in to find the root cause of
performance problems.
Network Navigator
Ensure Consistent End-User Experience and Network Performance
Advanced Network Discovery – Finds Devices,
Networks and Problems in Seconds
As soon as OptiView XG is connected to the network, it automatically begins to
discover devices, with no user interaction required, by monitoring traffic and actively
querying hosts. IT staff can see what is on the network and where it is connected, by
switch, slot and port number. They can investigate and locate "suspect" or rogue
devices and identify problems associated with device misconfigurations.
The OptiView XG categorizes devices by type: interconnect (routers, switches),
servers, hypervisors, virtual machines, printers, SNMP agents, VoIP devices,
wireless devices, and other hosts. Additionally, networks are classified by IPv4 and
IPv6 Subnets, VLANs, NetBIOS Domains and (legacy) IPX Networks, and Wireless
Networks together with host membership within each classification. Network devices
experiencing problems are also discovered.

Discover and Analyze Remote Networks
Most network analyzers and troubleshooting tools have limited visibility – usually a single broadcast domain or VLAN. The OptiView XG Network Analysis Tablet can be
configured to perform discovery of up to 30,000 devices on off-broadcast domain subnets to extend its discovery beyond the broadcast domain or local VLAN boundaries
– across your enterprise network, into remote sites and users anywhere in the world. Generate up-to-date HTML and PDF format inventory reports of devices both on the
attached network and on remote sites.
To test performance to and from remote sites, use the Network Performance Test feature (see Performance Testing Key Use Case.)
Application Infrastructure Analysis
Consistent application delivery is critical for business. OptiView XG makes it easy to
identify and analyze the underlying network infrastructure of an application. This lets
you become proactive about network health issues.
Speed up troubleshooting network infrastructure issues by automatically validating
that network services such as DHCP and DNS are available and operating correctly.
Ensure that server and application connectivity is accessible by opening specific
TCP IPv4 and IPv6 ports on servers and reporting the round trip time as a
combination of network latency and server connection set up time. Ensure servers
are operating efficiently by viewing resources including number of users, processors,
memory and disk utilization, as well as services and processes that are running.
Application Infrastructure Analysis
Discover and Test Through Wireless Connections
OptiView XG's unique capability for fast discovery through a wireless connection keeps you aware of the surrounding network when moving through your site. You can
unplug from the network and be confident that the tablet is analyzing your critical devices wirelessly, even when moving to a different location – without losing any data.
This offers a perfect solution for testing roaming handoffs.
VoIP and Wireless Device Discovery
The OptiView XG will discover VoIP devices including call managers and IP phones
from Cisco®, Nortel®, Avaya® and Mitel®. Device capabilities and configurations
may be viewed, allowing the user to identify and correct configuration issues during
VoIP deployment. The OptiView XG also discovers and categorizes wireless LAN
controllers, lightweight access points (AP), intelligent access points and wireless
clients. Detailed device information is provided from Cisco Wireless LAN controllers
and LWAPs, including the wireless networks associated with the controller, the
SSIDs, security and QoS parameters, the lightweight APs being controlled and the
802.11 protocol in use. With XG version 12, users will be able to instantly generate
maps of their wired and wireless infrastructure.
Wireless Infrastructure Discovery
IPv6 Discovery
The OptiView XG will discover and display complete IPv6 network and device
inventory including routers, switches, wireless APs, DHCP6 servers and hosts. It
enables you to identify active IPv6 devices in the network and those that may have
problems in single-stack IPv6 networks. Router advertisements are analyzed and the
OptiView XG displays detailed router information and settings. Easily identify
applications that may be communicating using both IPv4 and IPv6 protocols.
