Have you spoken to your reseller for assistance? Most will have engineers who will gladly give some guidance FOC if it's a new purchase.

Using the command line utility 'airport' in the command line you can force the mac not to roam.

The rule of thumb is as follows; if it's Procurve, it will need genuine HP. If it was born from comware (a 3COM legacy derivative) it will take just about anything.

Apologies, there was a mistake in my previous post. I am seeking clarification this afternoon.

I believe the Meru model is protected by patent and cannot be copied. The Extricom single channel or 'Blanket' model requires each AP to be wired back to an Extricom controller rather than any switch on the network.

Both work well when deployed in the right way in the right environment. Sometimes multi cell os a better choice, other times single cell is better. Many factors need to be considered some of which are; Throughput requirement Concurrent connectivity 802.11ac viewpoint Building(s) layout and construction Legacy experience (people often choose one or the other because it's all they've ever know) A pre-sales discussion to understand the differences and the choices is as important as the pre-installation RF survey.

Some bold statements in there. Here are some facts. Meru Networks outperforms Cisco and Aruba in 802.11ac testing: Tolly Group - ARN

I would definitely look at a solution which offered some sort of segregation such as a Bonjour gateway where multicast traffic is converted to unicast based on a set of policies. This will restrict the number of devices advertising within certain areas.

In a nutshell.... The 5120 is faster, has more functionality, is fully manageable. Click for full specs

It's all about budget and requirement and budget again!

I would echo my comment re the 5406 and its blocking. It will only handle 2 x 10G links at full speed per slot. Why not virtualise with a suite of 5800s creating an IRF. The 5406 has now been replaced with the 5406R which whilst increasing the backplane speed is still blocking at 2:1. No word yet of v3 modules but v1 modules definitely not supported whereas v2 will be.

Not really enterprise grade only offering 300Mbps. This will likely grind to a halt with more than 10 concurrent connections. Routers in each classroom? Can you expand i.e make and model,what sort of routing you're doing.

Most, if not all vendors have dual radio APs. If you are planning for the future, consider the ac option too. A very interesting post by wotnowires on this page....http://www.edugeek.net/forums/wireless-networks/138054-meru-vs-ruckus-4.html

Tolly Report #214124 Meru Networks WLAN Performance vs. Aruba Networks & Cisco Systems - 802.11ac WLAN Systems: Meru Networks AP832i vs. Aruba Networks AP-225 and Cisco Systems Aironet 3702i Here's a new report on the subject which may assist some buyers.

Although the stretch layer 2 method is simple and easy to implement, it would be a step backwards if you have many users connected to each of your spokes.Traffic flow will be controlled more effectively if you use layer 3 routed links with routes to each destination.

Why would you want to increase the traffic into your 'core' location? If individual schools do their own routing then only traffic destined for other schools needs to cross those boundaries. We now have schools in the UK who are not only routing within individual schools but some are routing in their own edge cabs. Whilst it may be overkill for some establishments to go this far it is highly efficient and most importantly, robust.

I am suggesting that the number of 2.4 clients will probably fall off as the number of AC clients rise. If that is the case then the need for a 2.4 radio will be diminished.

Also worth a thought is what happens to your dual radio AC AP (2.4GHz & 5GHz) when the 2.4 clients start to, and completely disappear. I am told that some vendors' APs will operate 5 on both but some will effectively have a redundant radio.

Problems with DIY solutions such as WAP on a stick and Android app is that you won't get heat maps showing any or most of the following which you would get with Ekahau or similar; Minimum Signal Strength Minimum SNR Minimum Data Rate Number of Access points 'seen' Max Ping round trip Max Packet loss But as always budgets dictate.

If you want to PM me with an email, I will send you a link to the full document.

You can connect as many 10G connections as your modules will take but if more than two get max'd out then blocking will occur.

This is a small extract from a tech paper on the 5400/8200 chassis. For wire-rate connectivity, do not connect more than two 10-GbE ports to a channel . In Figure 24, it is possibleto connect ports 1–4 for wire-rate connectivity because the first channel will have ports 1 and 4 connected,while the second channel will use ports 2 and 3 . If ports 1, 4, and 6 are connected, but other ports areunused, the three ports will share up to 23 .4 Gbps of bandwidth . If ports 1, 4, 6, and 8 are connected, theports will share 23 .4 Gbps of bandwidth between the four ports . The E8200 zl series can support up to fourwire-rate interfaces on an 8-port 10 GbE module (J9538A) . The 10 GbE module (J9538A) delivers additional performance for E5400 zl Switches . When compared to thefirst-generation zl modules, the bandwidth channels have been improved to a maximum capacity of 15 .8 Gbpsper channel, as opposed to 14 .4 Gbps channels for the standard zl modules . An 8-port 10 GbE module hastwo 15 .8 Gbps channels, for an aggregate of 31 .6 Gbps of channel bandwidth . There is a fixed assignmentbetween ports and channel bandwidth . For 8-port 10 GbE modules, each 15 .8 Gbps channel is allocated tofour 10-GbE ports .

Cost depends on the size of the campus and the complexity. A company will usually quote based on a set of building plans and discussions Some companies might refund the cost against an order for a new wifi system. A proper survey is done using an AP of choice with Ekahau (or similar) software installed which costs an arm and a leg hence the charge for the survey. The survey company will also typically use an RF spectrum analyser to check for interferers such as Radar, PIR detectors, etc etc. Hope this helps
