It's that time of year again to make the pilgrimage to Las Vegas to learn about the latest and greatest enterprise wireless solution - Aruba Networks.

Problems upgrading to ShoreTel 14.2?


I've been banging my head against the wall for the past few days trying to figure out why my upgrade of ShoreTel 14.2 was failing with WinVerify Trust errors during the upgrade.

Server is running Windows 2008 R2 with latest Microsoft patches as of 02/11/2014.

Five Nines a Reality with Nimble Storage

System crashes are never pretty.  At best, they’re a nuisance for users who‘ve come to expect 24/7 access. More typically, system downtime means lost productivity, disaffected customers, and a hit to the bottom line. And, the bigger the organization, the greater the vulnerability ­ – and the damage they can potentially suffer.

Juniper Networks Contrail is here


We're all hearing a lot about SDN, but usually it's discussed in the future tense!  Customers and vendors are promising major management and virtualization benefits, all of which will eventually be delivered by SDN.  Well, the good news is that SDN is becoming much more real every day!  For example, Juniper has supported programmable network elements (switches and routers) that can communicate with an SDN Controller for over a year.  These have been successfully deployed in several large-scale enterprise and cloud networks.

The ShoreTel Dock Cometh


Extra, Extra read all about it....the ShoreTel Dock Now Shipping!!!  I'm not an Apple iOS fanboy, but I do think this solution from ShoreTel is pretty slick.  I wish they would come out with an Android based dock, but the chances of that happening are probably slim to none, due to the fact that there are so many variants of Android based tablets.

Windows Server 2012 R2 and Drupal 7


When it came time to build a new server for our new website, we decided to go with the latest and greatest version of Windows Server 2012 R2.  There wasn't a lot of information posted about whether or not Drupal 7 would work on the new platform from Microsoft, but we decided to press on.  It was a pretty easy install, thanks to the Web Installer in IIS 8.  We used the installer for PHP, but manually installed MySQL and Drupal 7. 

A Case for Aruba’s ClearPass Access Management System

A recent article from the CIO Journal (see below) discusses the security challenges in the workplace posed by tablet computers.

This is a case where the workplace can benefit from Aruba’s ClearPass Access Management System.  (Especially in this ever-expanding mobile landscape, where personal devices have taken the lead!)

Aruba Campus APs: To which am I connected?

Ever wanted to confirm that a specific AP is properly participating in the air?  Or needed to determine which specific AP your mobile device is connecting to?

There’s the “low tech” method... take the device, touch it to the AP, and if the “signal strength” reaches “Excellent” (or dBm is better than -40), then that’s probably your AP, and it is probably functioning just fine.

But, there’s a better way to verify, by comparing BSSIDs.  With a mobile device and a wifi analyzer app, you can see which BSSIDs are nearby / connected to you, and compare that with the Controller.

Troubleshooting Aruba Campus Access Point Deployments

You’re out deploying a Campus AP to your network, and it doesn’t seem to come up -- doesn’t broadcast, repeatedly rebootstraps, never lights up with all green LEDs.  It’s getting power.  Existing APs are working fine. What gives?

 Here’s a list of common causes...

 * The AP does not have a valid IP configuration.  It requests via DHCP by default.  Is DHCP available?  Reachable from that endpoint?  OR, if IP config is statically defined, double check settings.  (see TESTING, below)
