Backhaul

The purpose of a wireless network is to connect traffic to a wired network for backhaul to servers.

With 802.11ac's raw data rate at 1.3Gbps max, but actual "Goodput" considerably less, will a single 1 Gigabit wired connection be adequate for Phase 1? In Phase 2, will we need 10 Gig links or will dual 1s be sufficient?

Stay tuned - we're going to talk about readiness and the wired side of the network in a couple of hours.

I think Wave 2 will also come with 1Gbps Ethernet interface. All these big numbers are just theoretical values :)

For more discussion on backhaul, see the question 6 thread: http://community.aerohive.com/aerohiv...

To answer the question posed at the start of the thread, I think 2x1G connections will be sufficient for wave 2, but it is important to get both wires installed as early as you can. I've typically found that running two wires to each location adds only a small amount to the wiring project cost, but going back and pulling a second wire costs double.

Matthew - When hooking up that 2nd Ethernet cable to the AP (AP230 in my case), how should I set it on the HMOL side?  Is this for failover or aggregation (2GB total)?  I'm sure I'll need to do some trunking on the HP Procurve switch side too.

Can someone answer my question above for me?  If I ran out two Cat 6's to ever AP, can I simply plug them both in to the AP, change the Ethernet settings in HMOL to aggregate, and then plug them into the switch?  Or do I need to do something on the switch end too?  It shouldn't matter on the switch end, right?  The AP will do the aggregation, no?

No, it takes two to tango.

You'll also need a managed switch that support EtherChannel and to enable EtherChannel on the switch ports that you are connecting the AP to.

Look at the Static Link Aggregation configuration here for some reference: http://www.techieshelp.com/hp-and-cisco-link-aggregation-guide/
