HDX


• With 802.11ac, the total bandwidth available to clients is increased to 1.3Gbps, but this is still a shared medium technology.

• An efficient packet scheduler designed for the needs of 802.11ac is needed to keep up with client counts of 60+ per radio.

• Cisco’s AP3700 provides on-radio caching technology which leverages additional RAM for per-client queuing techniques.

Converged

Access

Control plane functionality on NG Controller (also possible on upgraded 5508s, WiSM2s for brownfield deployments, or NG Converged Access switches for small, branch deployments)

Increased Scalability, Centralized Policy Application

• Unified wired-wireless experience (security, policy, services)

• Common policy enforcement, common services for wired and wireless traffic (NetFlow, advanced QoS, and more)

Data plane functionality on NG Switches

(also possible on NG Controllers, for deployments in which a centralized approach is preferred)

5760’s as new Guest Anchors

Upcoming 200+ 3850’s deployment

interop with AireOS

3850 MC/MA deployed for student

rez tower – serving ~500 clients.

Installing 5760 as anchor for

CAPWAP


IOS XE 3.6 (Amur)

Features mostly caught up –

AVC, Bonjour GW, 802.11r, WEB GUI enhancements, PI 2.1 Support


Notable “Things” NOT in CA

1. Flex Connect

2. MESH

1. Support for 1552,1524,1522 -40°C rated outdoor Aps

(Note 1532 is supported but limited to -30°C)

2. Support for G1 Aps and older (think 1142 and older)

1. EOIP Mobility

(typically 4400’s,WISM1s that don’t support CAPWAP mobility)

2. High Density Tweaks (RF profiles, RX SOP, CCA)
