Key Features

The EtherScope nXG has two sets of native Wi-Fi network interfaces: a 4×4 adapter that scans and test Wi-Fi networks, and a 1×1 adapter for the remote control connection and testing. Both interfaces support 802.11a/b/g/n/ac and can show analysis of utilization and status of Wi-Fi channels, SSIDs, BSSIDs, access points, client devices, and interferers. The EtherScope X provides visibility of Wi-Fi 6 devices. The EtherScope nXG has two Ethernet ports. The main test RJ-45 port supports Multi-Gig networks from 10/100/1000Mbps to 2.5/5/10G to verify link speed SNR, and duplex advertised and connected. It can request and verify PoE power under load from up to 90W PSEs. Alternatively, it can interface to fiber networks via single/multi-mode SFP+ to test 1/10Gbps fiber-based Ethernet. The second RJ-45 management port connects to 10/100/1000Mbps Ethernet for remote control and conducts network scanning and tests where needed. It is also the port for cable testing. The EtherScope nXG has built-in Bluetooth v5/BLE and USB interfaces to discover and configure nearby devices.

Ethernet Network:
switch port PoE characteristics, VLAN Tagged traffic detection, 802.1x authentication, link speed advertised vs negotiated, DHCP/DNS/Gateway availability and accessibility. Air Quality: assess the number of APs, co- channel and adjacent channel interference, and channel utilization
Wi-Fi Network:
supports various authentication and security schemes to connect to SSIDs/BSSIDs for coverage by signal/noise, and DHCP/DNS/ Gateway availability and accessibility.
Multiple profiles can be created for complex networks with multiple VLANs supported per switch port, and Wi-Fi networks with multiple SSIDs each with its own set of IP targets. These can then be organized into profile groups that execute each test against each profile in sequence. The result is that multiple VLANs, and SSIDs can be verified and documented in one go. Since the predefined profiles can be executed individually, the profiles group serves as a resource for technicians to verify each specific VLAN or SSID during troubleshooting. With profile groups, engineers can transfer their network configuration and test knowledge to technicians, saving training time and effort.
24-Hour Monitoring for Intermittent Issues
Periodic AutoTest
In this mode, AutoTest runs at specified intervals (from 1 minute to 24 hours) and sends the results to Link-Live to view the results over time. This is an effective way to “monitor” aspects of your network for an extended period or to help diagnose intermittent issues without having to manually execute multiple tests. Results are automatically timestamped and can be prefixed with a user-entered comment for grouping or organization. Test results can be quickly analyzed in Link-Live using the filtering and sorting functions. Email notifications can warn you when errors are found. A number of additional enhancements in version 1.2 expand the use models for EtherScope nXG, provide more actionable information, and make the network analysis process even more efficient. See the EtherScope nXG v1.2 release notes for additional information.
Multi-Gig Link Validation
With the expanding deployment of Multi-Gig switching (typically to feed greater bandwidth to Wi-Fi 6 access points), users are finding that their cable plant may not support the desired speed. Cable quality, length, installation workmanship, and noise in the environment all can contribute to “downshifting” to lower-than-expected speeds.
• Cabling SNR Measurement – EtherScope nXG can now verify copper media for Multi-Gig capability (1 / 2.5 / 5 / 10Gig), and provide root cause diagnosis when link speed downshifting occurs.

List of Problems

Wi-Fi AutoTest – Link Validation

The Wi-Fi AutoTest runs a series of tests by connecting to a selected wireless network (associate to an AP), providing a status indication of Success, Warning, or Fail. This comprehensive test validates not only the Wi-Fi connection but also each critical supporting network service.(Note: Wi-Fi AutoTest supports connecting to Captive Portals where a sign-in is required for access; see User Guide for instructions.)

• Wi-Fi Link Test – validates the ability to connect to the selected network. Drilling into the link test provides in-depth information about the SSID, signal strength/SNR, channel utilization, retries, and PHY rate. Of note, Roams indicates the Number of times the unit has disconnected from the previous AP and connected to a different AP with better signal strength.
  The Wi-Fi Link Test graphs save and display data for up to 24 hours in the past, providing a way to “go back in time” to identify specific problem instances.

• Channel Test – shows the channel on which the AP is operating and the current 802.11 and non-802.11 utilization in real time, and plots the percentage of channel capacity used by devices and non-802.11 interference.

• AP Test – shows the AP name and SSID of the network it supports, its IP and MAC addresses, security, channel (if the BSSID is on multiple channels, the bold number indicates the primary), 802.11 types supported, and client associations (number of clients connected to the AP).

• DHCP, DNS, Gateway Results – these validate the availability and performance of critical network services via the Wi-Fi network. Diagnostics on each test provide details on response times and logs for troubleshooting.

• Path Analysis – can be run from the above network services tests to identify the connection path to the specified service (or server); this is useful to determine if errors or excessive utilization on the wired network may be affecting the particular service.

Air Quality Test

The Air Quality Test performs a single scan of the channels in your wireless network to measure channel utilization and interference.
Each table on the Air Quality results screen shows the top four channels in each band with the highest utilization or co-channel interference, along with the number of APs operating on the channel.
Channel Utilization and Interference
Quickly determine if channels are over-utilized with Wi-Fi traffic and/or with non-Wi-Fi interference and noise. You can also gain visibility on the level of Wi-Fi traffic and interference over the last 60 seconds on a selected channel, as well as, the access points, clients, and interferers using this channel. Drill into details and detect devices that can cause interference, such as, microwave ovens, wireless game controllers, Bluetooth® devices, Zigbee devices, and wireless video camera.
Automated Problem Detection
EtherScope nXG automatically diagnoses various conditions on both wired and wireless networks and identifies specific problems. Tapping the Problems card shows all discovered issues, which can be sorted by severity or time detected. Drill in to see a detailed description of the problem and recommended course of action to mitigate.

10G copper/fiber wired and Wi-Fi performance tests for critical links and key devices
The EtherScope X can stress critical network links, such as switch ports to servers/storage/Wi-Fi access points, uplinks or WAN links, with up to four simultaneous data streams at up to 10G line rate. It verifies the link’s compliance to service level agreements (SLA) based on throughput, packet loss, QoS, delay and jitter against peers such as EtherScope X, LinkRunner 10G, OneTouch™ 10G, OptiView® XGor a Windows-based software reflector agent. Settings for data streams and thresholds for VoIP or video service can be stored and recalled where needed, saving configuration time. Additionally, the EtherScope nXG can use the popular iPerf v3 network test algorithm to test against the NetAlly Test Accessory. It determines TCP or UDP application throughput through its Wi-Fi or wired interfaces. For key servers/services in the cloud or Internet, engineers can pre-define tests and thresholds to verify their connectivity and performance using ping, TCP connect, HTTP, or FTP. Continuous testing with response time measurements is available to verify consistency and identify intermittent issues. These tests can be easily recalled by field technicians to reduce configuration time or mistakes, to get more done faster.

Auditing & documenting network security & health 

The EtherScope nXG automatically discovers your network through its dual set of Wi-Fi and Ethernet test interfaces immediately upon power-up. The discovery provides quick security and health audits of the network devices across multiple VLANs and all Wi-Fi channels. Devices are classified and correlated to provide complete visibility of their name, network addresses, VLAN, SSID, device type, and where available, traffic statistics. Engineers can name and set authorization status for devices discovered.

Discovery results can be directly uploaded to the complimentary Link-Live Cloud Service for storage, conduct detailed analysis of devices discovered with filter and sort tools, or export to CSV/PDF files as documentation. The EtherScope correlates the discovery result from the wired and Wi-Fi networks and breaks the layer 2 visibility ceiling. EtherScope nXG makes it easy to discover the actual identity of a Wi-Fi device by showing its name and IP address while most other Wi-Fi tools only show the MAC address. EtherScope nXG’s discovery can be enriched by accessing SNMP MIBs of infrastructure devices. It shows details such as device configuration summary, interface configuration and traffic detail, SSIDs supported by WLAN Controllers, and devices directly connected to switches. Community strings entered are concealed from view. Discover possible security risks caused by users and others: 2nd DHCP offers indicating possible rogue servers, APs with different security schemes, unknown or unauthorized devices, unknown switches granting access to multiple devices, and hidden SSIDs. EtherScope nXG’s “Batch Authorization” workflow allows the user to filter discovery data to a subset of easily identifiable devices, then apply a “label” to the grouping (such as “Authorized” or “Neighbor”) to the list of devices. Labeling known/acceptable devices makes it easy to sort/filter and identify unauthorized hosts in subsequent audits – so you have clear knowledge of who and what is on your network, and whether they should be there or not. The EtherScope nXG discovery automatically detects problems. It shows possible cause(s) for each problem detected, and it has integrated troubleshooting tools to investigate further to get to root cause.

Simple “access-anywhere” remote control enables collaboration
The EtherScope nXG has dedicated Wi-Fi and Ethernet management ports that enable a more xperienced/knowledgeable remote engineer to control the EtherScope nXG “out of band” (using VNC) to collaborate with technicians on- site, or to troubleshoot remotely where there is no local staff. But connecting to distant sites via VNC on different networks is difficult or impossible, particularly behind NAT firewalls. With the AllyCare-enabled web remote control feature, users can instantly connect to remote units through the Link-Live Cloud Service – anywhere in the world – for collaborative and remote troubleshooting. At locations with no Internet service, the Wi-Fi Management Port can connect to a personal Wi-Fi hotspot for remote control, and upload results to the Link-Live Cloud Service.

Automated test results management

the complimentary Link-Live Cloud Service transforms team workflows with the ability to quickly and easily log, document, and report test activity from any NetAlly LinkSprinter, LinkRunner AT, LinkRunner G2, AirCheck G2, OneTouch AT, and EtherScope nXG network testers. Once the tester is connected to the Link- Live Cloud Service, your test results are automatically uploaded to the dashboard for project management and reporting. You have the option of uploading additional files, screenshots, images, profiles, packet captures, location information, and comments anytime. Also, certain NetAlly testers with AllyCare Support can receive firmware updates “over the network” from Link- Live as they become available. An API is available to retrieve and integrate data from Link-Live into other management platforms, such as your trouble- ticket application or network management system. It gives you the ability to provide proof of performance and better manage jobs and staff efficiency. This unified dashboard of both wired and Wi-Fi network connectivity results enables you to:

•  Reduce results management overhead for multiple testers and users
•  Enables seamless collaboration between site personnel and remote experts
•  Simplify report generation across media types for network deployment documentation
•  Attach photos, user comments to each result, adding context for future changes and troubleshooting
•  For asset management, ability to associate serial numbers of installed devices, and/or cable/walljack label to specific test results

Multiple advanced troubleshooting tools in one

• Path Analysis: shows the switch/router path connecting the EtherScope nXG to an IP device on across wired and Wi-Fi networks, and even beyond the local network, e.g., from the EtherScope nXG’s Wi-Fi port to a server in the cloud or data center on the Internet. The EtherScope nXG offers built-in tools to conduct further analysis of the devices along the path: view configuration, interface traffic statistics, launch Telnet or browser, conduct port scan, ping and more.
• Packet Capture : from both the Wi-Fi and Ethernet test interfaces. You can capture up to 10G line-rate to create a PCAP file of up to 1Gigabyte. Packet slicing and filtering are supported, and PAP files can be uploaded to the Link-Live Cloud Service for easy sharing.
• Cable Test: determine length, shorts, and split pairs and locate opens on UTP cable. Verify the wiremap of UTP and ScTP cable with a WireView adapter. It can generate either analog tone or the unique digital tone for the Fluke Networks IntelliTone™ Probe for quick cable tracing.
• Android Apps: Users can download apps from the Link-Live app store to accomplish many tasks in addition to testing.

EtherScope™ nXG Controlled Edition
Allows administrators to temporarily or permanently hardware-disable selective features for restricted environments With the Controlled Edition, administrators can disable specific EtherScope capabilities allowing the analyzer to be used in restricted or secure environments. The Controlled Edition is ideal for military and agency use, as well as highly secure enterprises. Control may be temporarily achieved via a secure administrator password. To make the controlled configuration permanent, the administrator follows a clear workflow that fully disables the selected functions using eFuses in silicon, that once burned, cannot be reversed, ensuring the security of the unit.

•  Builds upon the enterprise hardened EtherScope to allow additional hardening by removing capability
•  Allows custom granular control of the exact features and capabilities to be permanently disabled
•  The camera is physically removed while retaining the opening for flashlight operation
•  User accessible deep erasure of all test data upon leaving secured environments
