I Friggin LOVE You, NetAlly LANBERT

His name was LANBERT and he came from the west
To show which cables sucks and which are best
With a push of a button it’s doing it’s stuff
Hopefully for mGig the existing wire is enough…
Oh looky there, this one passes just fine
That LANBERT just saved us money and time

–Ode to LANBERT, by Wendall Pissmont Jr

There’s a new Bert in town… forget about Reynolds*, Bacharach*, and that whiny neurotic muppet from Sesame Street. Them cats is yesterday. NetAlly has recently introduced LANBERT (at Mobility Field Day 6), and if you are in the business of network wiring then you should pay attention.

This was easily one of the more thought provoking sessions of MFD6, says I. Let’s set the stage: you have an installed cable base, and are migrating access points to Wi-Fi 6 and 6E, and at long last we hopefully will see the massive throughputs that WLAN industry marketers have been telling us we should expect for years… like to the point where the old reliable 1 Gig uplink may not cut it. Do you need to replace that cable to get mGig performance?

LANBERT to the rescue! There should be no mystery when it comes to cabling performance capabilities. Many of us grew up knowing the value of cable certification testing, and now the free LANBERT app adds a much needed evolution to the notion.

Working with NetAlly’s Etherscope nXG and and LinkRunner 10G portable analyzers, LANBERT “generates and measures the transmission of line rate Ethernet frames over your network cabling infrastructure, qualifying its ability to support 1G/10G on fiber and 100M/1G/2.5G/5G/10G on copper links.” You are proving what an installed UTP or fiber run can really do despite what a certification report might say, without needing a standalone certification tester.

Test that existing cable for mGig before the new AP goes in, and don’t assume that “old” runs can’t support the new speeds.

I’ve long beaten the drum that the physical layer is critical to good networking. I’ve always viewed each part of a structured wiring system as it’s own component, worthy of note when it comes time for labeling, troubleshooting, and yes- performance testing. I’ve seen old cable work surprisingly well, and new cable disappoint for a number of reasons. There is simply no reason to guess how UTP and fiber will perform FOR REAL, with LANBERT. It’s the shizzle, baby!

NetAlly Unleashes the Right Tester, at the Right Time: EtherScope nXG

 Change is both inevitible, and fickle. Vendors come, go, and buy each other. Some product lines that we love die on the vine, others thankfully go on to only get better with time. I sat in a room with the NetAlly folks at Mobility Field Day 4 and got an eyefull/earfull of teaser information on a slick new tester that would be released later in the year that would bear these notions out in spades.

I’m here to tell you- “later” is now, and the product line that we have grown to appreciate from its start at Fluke Networks, through it’s run as part of NETSCOUT, and now as the baby of spin-off NetAlly continues its tradition of excellence with the new Etherscope nXG.

Does this look vaguely familiar?
EtherScopenXG

If you own (or have Jonesed for) either the AirCheck G2 or the Link Runner G2, that color scheme will look familiar. But the EtherScope nXG’s overall feature set makes the very-capable G2 units suddenly feel a litlle less-than, despite each being a testing powerhouse in its own right. (And if you’ve been around a while, you might remember the old yellow EtherScope from the Fluke Networks

NetAlly brings the EtherScope to market right when it is needed. What do I mean by that?

  • With the 802.11ax tide starting to rise, troubleshooting tools need to keep up
  • On the wired side, NBASE-T and 10G are becoming facts of life
  • Bluetooth is penetrating the enterprise in interesting new ways
  • “Convergence” is one of those overplayed words in networking, but the reality is that both operations and support of those operations has very much seen a convergence and fewer of us do one or the other (not to mention work in data centers and server rooms)
  • Senior engineers can’t be everywhere, and it’s not uncommon to rely on others to gather data that we then analyze from some other location
  • Performance testing and detailed path analysis of different network segments can be daunting as topologies get more sophisticated.
  • Uploading of results to a cloud repository brings huge advantages in baselining, team-wide scrutiny, and reporting.

Networks are getting more complicated. Tolerance for time-to-problem-resolution is decreasing. The EtherScope nXG is marketed as a “Portable Network Expert”, and despite my frequent disdain for grandiose marketing plattitudes, I find this to be an apt description.

Rather than regurgitate the tester’s specs, let me point you to them here (scroll down).  The full data sheet from the product docs is here and shows the product’s impressive range nicely. And to get a feel for just what the EtherScope nXG can do, have a look at these videos that show several different testing scenarios.

I’m going to cap this one here. There is just sooooo much to talk about with this new tester. Yes, I know I sound borderline giddy and buzzed on the Kool-Aid- and I’m OK with that. I can tell you that the new tester feels good in the hand, and casual kicking of the tires is in itself impressive. I have an eval unit, and will be putting it through it’s paces for real in the near future. Watch for the next blog on the EtherScope nXG.

 

 

Document That Small Business Network Environment- Whether You Are the Customer or Provider

Small networks can still be complicated. But too often a slew of information that should be recorded for the benefit of the customer and the technology providers gets overlooked, because… well, it’s small.  That is, until the environment needs to be troubleshot or serviced in some way, and big questions can arise from sloppy or lacking initial documentation.

See the article I wrote on the topic at IT Toolbox, or skip write past it and check out a simple version of a checklist you might use to get you started when making sure the important documentation basics are covered when buying or providing a small business network.

This isn’t meant to be comprehensive or all-inclusive, but it is the kind of information I make available to my own small-site customers. It gives us a common frame of reference, and empowers the customer to better understand what they just purchased (which I find they almost always have been frustrated with from “the last guy”).
