At AirWave, people constantly ask us “Why is it important to select a vendor-neutral wireless management solution if I have an ‘all-Cisco’ [or all-Aruba, all-Symbol, all-Anyone…] network?”

A few things to consider:

• You might have a heterogeneous network and not even know it — In large organizations, the left hand often doesn’t know what the right hand is doing. Is it possible [likely?] that a division somewhere in the world purchased some equipment that you don’t know about? If you use only proprietary single-vendor management tools that only discover APs and controllers manufactured by your primary hardware vendor, you may never find out — and if you do have some other equipment out there, you won’t be able to manage it and enforce your security policies using your proprietary tool.
• Wireless technology is still evolving — and so are wireless product lines. WiFi is so ubiquitous that people forget that the technology is still young. Many new technologies and standards [802.11n, anyone?] are still being developed. Hardware vendors will implement these technologies on different schedules and in different ways. Using a vendor-neutral management solution gives you the ability to evaluate new offerings as they come out — and to select the ones that best meet your needs, even if they’re from someone other than your primary vendor.
• Mergers & acquisitions — in the U.S. alone, there were more than 11,000 mergers in 2006. Every time corporations merge, IT has to knit together the diverse infrastructure of the two entities. Smart IT organizations understand this and select vendor-neutral management tools that enable them to control the infrastructure they have today — and what they’re going to inherit tomorrow.
• Maintain flexibility and control your own destiny. If you rely on proprietary management solution, you don’t control your network — your vendor does. If your vendor end-of-lifes management support for your product, you’re stuck. Time to upgrade. When you’re negotiating the price of your hardware, you’re not going to get much of a discount if your provider knows that your management solution won’t allow you to switch to a competitive product. If you’ve got flexibility, you’ve got leverage.
