Netool.io Pro2- A Good Thing Just Got Better

Netool.io Pro2 at Wirednot HQ

Today’s network tool market really isn’t all that big. We love our support tools, sure- but if they don’t bring consistent value, they won’t stick around. Back in 2017, I think it was, the small Nevada company brought the original Netool to market. I wrote about the introduction of the Pro model back in 2020. Now, three years later, we see the company and the product have stood the test of time.

For those totally unfamiliar, all versions of Netool.io are meant to be highly pocketable (or carried in the available belt holster) so those in the field working with Ethernet switches always have it with them. The tool talks via Wi-Fi (or now Bluetooth) to an application on your phone or tablet, and you connect a patch cable between the Ethernet port on the tester and a network switch. Then what? Let’s see some visuals.

There’s a lot more to show, but hopefully you get a general sense of what the little unit offers. Beyond pretty decent characterization of the local environment, there is a switch configuration side as well. Complete feature list stolen from the Netool.io web pages:

Netool.io Pro2 Features

The USB-C charging port is handy in today’s world, as is the ability to connect a flash drive for .pcap storage during packet capture. CPU and memory are bulked up over the last version, and run time exceeds a typical busy work day.

I have been playing with the Pro2 in my home lab environment which at current is Meraki and Ubiquiti on the wired side (the Netool is not a wireless tool, remember). It’s peppy, easy to pull information and performance feedback from, and I am a fan of the new Netool.io Cloud service. In my opinion, NetAlly absolutely aced this way of storing and sharing test results with their Link-Live service, and it’s nice to see another network field tool provider follow suit.

My current on-hand cloud-managed switches don’t lend themselves to benefit from the config capabilities of the Pro2, but other environments I do manage could absolutely benefit and I look forward to trying out the possibilities again, having kicked tires a bit on the earlier Pro version. One example of configuration capabilities is here.

It really is an impressive, super portable tool that pretty much any network field technician would benefit from. On my wish list for refinements would be a single app for all models of the tool. Right now there is an app per model- no one’s biggest problem but feels a bit odd. Also, Power over Ethernet has become such a pervasive part of networking that I would hope to eventually see some basic PoE verification in the Netool.io mix.

Introducing Netool.io Pro

Let’s get right to the cliche, as it’s unavoidable: good things sometimes come in small packages. Netool.io proved that a few years back when they introduced the original version of their feature-packed pocket-sized network analysis and support platform, and now with their Pro version I guess we can say BETTER things also come in small packages.

The Original

Netool.io is a small US-based company, and I have been following them since Day 1. They are responsive to customer requests, quick on the support response, and quite active in their development. The visual on the original white version, then the no-slip grip black, for reference:


The quick value proposition for those not familiar: using Android or iOS apps, you connect to Netool.io via it’s built-in Wi-Fi, then rapidly demystify a slew of network goings on ranging from the config parameters of the Ethernet port you are connected to, overall information on the connected switch, key network performance indicators and more. The original feature set is detailed here.

Now, the Pro Model

With their initial offering, Netool.io proved that a legitimate piece of network support gear could fit in your pocket with room for your phone left over. Now, the company takes it up a significant notch with Netool.io Pro. The visual:

Note- the USB drive is NOT included, but I’m showing it connected as I was doing packet capture on my Netool.io Pro. That is one of the many features that came from the Standard version, and it worked very well in my test environment as part of the new platform. So what was added in Pro? The official feature overview is here, but the short version is configuration and automation interactions with network switches on an impressive level. From IF/THEN templates that can be imported and exported to other Netool.io devices (for supported switches) to log gathering and views to other configuration automation capabilities, the little Pro version looks to make it’s mark in an industry that is thirsty for labor saving (and error reducing) automation. It’s impressive to see this sort of capability in the Netool.io on top of everything else it can do, and the company has managed to make the UI fairly intuitive throughout- even for the more complicated operations.

There is a lot here to take in, but this video will help you to understand all that has been added in the pro edition:https://www.youtube.com/watch?v=jkGhYP_qWL0

Here are the current supported switches, with more to be added as updates hit:

One wonderful thing about Netool.io: you buy high-function, fairly priced products, get a slew of features and capabilities (including Netool.cloud remote share if you choose to use it) without the headache and nickle-dime licence-heavy mentality of other toolmakers.

If you are in the business of network support at all, Netool.io should be of interest to you. And if your duties include switch configurations and automation is on your radar, the Pro version is definitely worth looking at.

Ethernet Is Done. It’s Time To Get Serious About Wireless.

Did you happen to see the PR on the Microsoft Surface Pro 3?


Evidently, there is a killer among us. A laptop killer. Laptops have Ethernet ports. If Microsoft’s new $800 assassin kills the laptop, it also kills the laptop’s Ethernet port. Goodbye, Ethernet, we hardly knew ye. Don’t let the door hit you in the ass.

As I look around at the many computing devices I have in my immediate vicinity, I see other models that have already started chipping away at the TRADITIONAL laptop’s tenure, like these:


For the record, that’s an iPad, a Chromebook, a Nexus 7, and a MacBook Air. Nary a one of them has an Ethernet port…

This is where some of you are thinking “Lee, you’re daft. Microsoft is touting the Surface Pro 3 as a laptop killer, not an Ethernet killer”. And though you’re right on that point, there is a nuance here that should be appreciated. 

There’s a certain significance to Microsoft trying to “kill” laptops with it’s new tablet (of course, you need to buy the add-on keyboard if you want to actually put bullets in the gun that will do the killing, in this case). Why? Well, because for the last several computing millennia, Microsoft has gotten fat off of it’s operating systems running on… wait for it…laptops! With the messaging that accompanies the Surface 3, MS is saying “we now commit our client access future to the tablet.” And tablets don’t have Ethernet adapters.

Right now, the client access world (forget about game consoles and the whole IoT malarkey for now, we’re talking “people clients” here) features:

  • Smartphones
  • Tablets
  • Laptops
  • Desktops
  • Thin clients

And not much else. Though desktops and thin clients typically are connected via Ethernet, they certainly don’t have to be as there are a range of wireless adapter options in this space. And if Microsoft fulfills its (rather silly) prophecy of making laptops extinct, the list of devices that come with stock Ethernet capabilities shrinks even further. To me, when I add a keyboard to a Surface 3, it just became a laptop again. But now it’s like the Chromebook and MacBook Air; a laptop with no Ethernet.

None of this rises to the level of epiphany, I realize. At the same time, Microsoft’s message that it’s willing to contribute to the erosion of Ethernet by killing off a class of device that ships with Ethernet adapters in favor of another class that doesn’t is worth holding up to the light and contemplating. For many of us, Ethernet switches have already become glorified VLAN-capable power blocks for our wireless access points. And I personally can’t recall the last time I’ve plugged a laptop into the wall to get on the network.

History will show that The Age of Mobility and The Age of Ethernet For Access absolutely had to have had overlap as technology evolves. But it’s interesting that Microsoft is beating a drum pretty loudly that leads further away from the wire and deeper into wireless.

Whether the Surface Pro 3 sells well or not is almost irrelevant, in my mind. It’s the message that comes with it that means our WLAN environments just got that much more important to network users. This should resonate with network designers, helpdesks, and bean counters alike. 

Interesting times…




With 11ac, The WLAN Industry Owes Customers A New Kind Of Network Switch

I realize I’m beating the 11ac thing up pretty good lately, but I think I finally hit on what bugs me about the way the new hot technology is being brought to market. What I’m about to describe is more of a BAN issue (BAN=BigAss Network, where APs are counted in the hundreds or thousands) and not so much of concern for smaller environments.

802.11ac is being delivered in rather bizarre (for the customer) “waves”.

  • Wave 1: Data rates to 1.3 Gbps. You’ll do fine (for most new first wave APs) with a single Gig uplink, and many new APs will work on 802.3af POE, not yet requiring .3at. Fine, good. No real squawks.
  • Wave 2: You get the joy and cost of recabling your environment to add a second Gig uplink, doubling the number of switchports in use for the WLAN and configuring Etherchannels, and depending on what vintage switches you have- upgrading them for latest POE standard, all to help get to data rates likely to realistically be between 2 and 2.5 Gbps best case.

And this is where I say “time out”. I’d like the WLAN makers to bear some of that Wave 2 logistical pain. And I want them to get creative to take the onus off of the customer. Here’s what I want:

  • In simplest terms- I don’t want to use two cable runs. And I don’t want the complexity and risk of 4000 more Etherchannels for my APs. But I still want the benefits of 11ac Wave 2.
  • I would like the WLAN vendors to put their brilliant minds (and that I do mean sincerely- these guys and gals accomplish amazing, amazing stuff) to work to come up with a new switch or mid-span injector. Here’s the requirements:
    • No feature bloat. May not even need to be VLAN aware.
    • Provides lots of PoE
    • Somehow puts 2 Gbps of uplink to an AP on a single UTP run without requiring me to configure a port channel
    • Cost effective (by customer standards), no licensing BS, and ultra-reliable

Spare me the lecture that there is no such thing as 2 Gig Ethernet, and that what I’m asking for would be based in no existing standard. The WLAN industry has long since turned it’s back on standards and interoperability, which is why vendor lock prevails. Other than PoE and what comes out of the antenna (and even that can be a dubious discussion), the mention of standards is a joke in the WLAN industry as each vendor authors their own technical magic. So be it- I just want new magic and don’t care that it’s not exactly Ethernet in the middle.

I’m OK feeding this new component a 10 GB uplink that it then divvies up into auto-configured 2 Gbps AP uplinks of some proprietary protocol. Or feeding it 2 single-gig ports on my wireless management VLAN that it then magically muxes into a 2 Gbps, big powered uplink that connects via a single wiring run (of excellent quality, of course) to each AP. At that point, all of MY work was done in the closet, and I didn’t run a slew of new wires for my wireless network.

If we don’t get something disruptively creative on the wired side to go along with 11ac, pretty much any TCO discussion on new 11ac ownership presented by WLAN vendors will be incomplete at best, and poppycock at worst. I’ve seen both announced and unannounced 11ac products- and the prices are pretty steep (well, except for Ubiquit-). But we’re supposed to believe that 11ac lets us draw down the wired network considerably, and so be willing to buy into a higher premium for wireless. But… adding lots of new switchports and cabling runs (not trivial in many environments,  can add hundreds of dollars in cost to real TCO for each AP) has to be considered.

As a customer, I feel OK asking- because the customer is always right (well, except when they’re wrong). So… when will my new non-standards-based 2 Gbps mega-PoE switches arrive?
