Converged Access One Network within Unified Access


Next Generation Branch Deployment Converged Wired/Wireless Networks

BENEFITS • Single platform for wired and wireless • Better network auditing for applications • Single point of configuration for both Wired and Wireless • Consistent policies for service control including AVC •  Improved network control (Fair Sharing) • Higher network bandwidth at the edge (802.11ac and 40G) • Reduced TCO • Smart and Optimal use of WAN Bandwidth

One Access Switch for Wired and Wireless


Built on UADP •  Unified Access Data Plane •  Unique and powerful Cisco innovation

•  Hardware performance with software flexibility

•  Optimized Performance •  CAPWAP encapsulation/de-capsulation,

Flexible Netflow, QoS happens in ASIC for line rate performance

•  Future Proofed and Programmable •  Flexparser enables new software features

(like SDN) over the product lifetime •  UADP is used across multiple modern platforms –

Catalyst 3850, Catalyst 3650, Catalyst 4500/Sup8E, WLC5760

Better Scale and Bandwidth with Converged Access Separation of MA and MC

Catalyst 3850 can play the role of both MA and MC Valid for Branch and small-medium campus type deployments Moving the MA only to the Catalyst 3850 (typically in large campus) helps with: Improved Scalability – larger mobility domains Increased wireless bandwidth Uniform wired/wireless policy enforcement WLC5760 works as external MC for large scale Converged Access deployments

•  Mandatory element in design

•  Maintains Client DB within a Sub-‐Domain (1 x MC = One Sub-‐Domain)

•  Handles RF funcJons (including RRM) •  MulJple MCs can be grouped together

in a Mobility Group for scalability

•  Manages mobility-‐related configuraJon of the downstream MAs

•  Can be hosted on a MA

•  Supported plaNorms are Catalyst 3850/3650, WiSM2, 5508, and 5760
