Test and Management Ports

The EtherScope nXG has two wired RJ-45 copper ports, a fiber port, and two Wi-Fi radios, each with specific test or management functions described in this section.

Either the top copper port or fiber port can act as the Wired Test Port, so in total, the EtherScope has four network interfaces:
1) Wired Test, 2) Wi-Fi Test, 3) Wired Management, and 4) Wi-Fi Management. The Wi-Fi test radio is controlled by the General Settings in NetAlly applications, such as AutoTest and AirMapper. The Wi-Fi management radio is set up by system network settings. See Selecting Ports below for more information.

See the sections below for more information on the ports. Also see Buttons and Ports and the technical Specifications as needed.

Test Ports

Wired Copper Test Port: The copper test port is the RJ-45 port on the top of the unit. To disable, unplug the connection.

Wired Fiber Test Port: The SFP and fiber test port is also on the top of the unit. To disable, unplug the connection.

Wi-Fi Test Port: The internal Wi-Fi test adapter is a 2x2 tri-band 802.11ax wireless radio. To disable, see General Settings in the testing apps' left-side navigation drawer.

NOTE: If both the top fiber and copper ports are connected to an active network, the EtherScope uses the fiber link as the Wired Test Port connection.

EtherScope nXG runs Wired and Wi-Fi AutoTests, Captures, Discovery, and other comprehensive network analysis apps over the test ports. The Wi-Fi test radio is primarily controlled by the settings in applications, especially AutoTest.

You must also run an AutoTest Wired or Wi-Fi Profile to establish a link on the Wired or Wi-Fi test ports. If the AutoTest app is not currently open, the last Wired Profile in the profile list runs automatically when you power on the unit or EtherScope detects a new copper link in the top Wired Test Port. Wired fiber connections and Wi-Fi Profiles must be started manually in the AutoTest app.

Note that the General Settings affect how you can use the test port. (The General Settings are accessible from the left-side navigation drawer from most NetAlly testing apps.)

The Use Wi-Fi test port option must be enabled for the test ports to function. (Enabled is the default setting.)

NetAlly also recommends that you enable all Wi-Fi Bands and Channels before setting up Wi-Fi Test Profiles:

1. Tap the Wi-Fi Bands and Channels option to open the Wi-Fi Bands and Channels screen.

2. Tap the Wi-Fi band(s) option to open a selection screen, and then enable all available bands.

3. Tap the option for each frequency band to open a selection screen, and then enable all available channels for each band.

This process makes it easier to set up the Wi-Fi Test Profiles, which you can limit to specific channels, APs, SSIDs, etc. See AutoTest Wi-Fi Profile for more information.

See General Settings for more information about all General Settings options.

Management Ports

Wi-Fi Management Port: The internal Wi-Fi management port runs on the main system's 1x1 Dual-band 802.11ac + Bluetooth 5.0 wireless adapter, which is configured in the system Device Settings. See Connecting to Wi-Fi to configure this connection.

The Wi-Fi management radio is set up by the system network settings. The radio provides full Internet access and a more stable network connection than the Test Ports, which may frequently drop links and reconnect or resume scanning.

EtherScope can run Discovery, Ping/TCP Connect tests, Path Analysis, and iPerf tests on the management ports, but not AutoTests, packet captures, or Performance tests.

Wired Management Port: The wired management port is the RJ-45 port on the left side of the unit.

Selecting Ports

Some of the individual NetAlly testing apps let you select which port interface to use for tests or analysis.

  • You may want to verify that you are getting a reliable connection to the Internet and the Link-Live cloud service while you are actively using the Wi-Fi Test port to perform an AirMapper survey. To check connectivity, you can configure the Ping/TCP app to use the Wi-Fi Management port to run a continuous background ping to the Internet.

  • Each port can connect to different networks. For example, an organization might have one network for visitors and another for staff. You can use multiple ports to check connectivity on each network without the need to link and relink through a single interface.

To change the port, tap an app's settings icon to display the settings screen. Then tap Interface to select the port from a dialog.

  • The top two Wired and Wi-Fi Ports refer to the Test ports.

  • An AutoTest Wired or Wi-Fi Profile must run to establish test port links.

  • The last listed Wired Profile runs automatically when you start up the EtherScope if a connection is available.
