What Capabilities Characterize a ‘Mobile-First’ Network?

1. Policy is unified and multi-vendor

2. Manageability is end-to-end and multi-vendor

3. Wireless is best-of-breed

4. Wired is optimized for wireless aggregation

5. Network analytics for IT, user analytics for LOB

Soon: 330 Series AP - 11ac Wave 2+

Aruba 330 Series AP - 11ac Wave 2+– Primary focus: Peak performance

– Adding 160MHz channel support (2x2)– 4SS SU-MIMO, 4SS MU-MIMO: 3x 1SS clients or 1SS + 2SS clients– Eliminate PHY bottleneck (NBASE-T, 2.5GbE, CAT5E ok)– QCA radio chipset, Freescale CPU, Aquantia Ethernet PHY

Aruba 310 Series Access Points: Mid-range 11ac Wave 2– Delivering the full value of 802.11ac Wave 2 at an aggressive price

– Same 5GHz radio capabilities as flagship 330 Series

– Single (Gb) Ethernet port, 2x2:2SS 2.4GHz radio

– 802.11ac 4x4:4SS MU-MIMO– 1,733Mbps peak datarate, and up to 3 MU-MIMO client devices

Case 2: 3810

– Customer need– 700 sites/branches– Building Management System – Overlay network– Zero-touch provisioning (ZTP)

– Initial proposal– Branch side: 3810 switches– DC side: 5400R (+ 3810)– Overlay: VxLAN– Routing: OSPF– ZTP: AirWave

Case 2: 3810

– Customer– “We want a layer 3 overlay, preferably GRE with BGP”

– Solution– Branch side: 5510 HI 48 port PoE+– DC side: HSR6600 routers– Overlay: GRE Tunnels with BGP routing– ZTP: IMC BIMS
