Description

Cisco 8540 Wireless Controller Ghana

The Cisco8540 Wireless Controller Ghana provides centralized control, management, and troubleshooting for high-scale deployments in service provider and large campus deployments. It offers flexibility to support multiple deployment modes in the same controller : for example, centralized mode for campus, Cisco FlexConnect mode for lean branches managed over the WAN, and mesh (bridge) mode for deployments where full Ethernet cabling is unavailable. As a component of the Cisco Unified Wireless network, Cisco8540 Wireless Controller Ghana provides real-time communications between Cisco Aironet APs and Cisco Catalyst APs, the Cisco Prime Infrastructure, and the Cisco Mobility Services Engines, and is interoperable with other Cisco controllers.

The Cisco Digital Network Architecture (Cisco DNA) is an open and extensible, software-driven architecture that accelerates and simplifies your enterprise network operations. The programmable architecture frees your IT staff from time-consuming, repetitive network configuration tasks so they can focus instead on innovation that positively transforms your business. SD-Access, as part of Cisco DNA, enables policy-based automation from edge to cloud with foundational capabilities. Cisco DNA Assurance, also part of Cisco DNA, provides a single source to monitor, modify, and manage your network and application data. Optimized for 802.11ac Wave 2 performance, the intent-driven Cisco DNA ready Cisco8540 Wireless Controller Ghana is a highly scalable, service-rich, resilient, and flexible platform that enables next-generation wireless networks for medium-sized to large enterprise and campus deployments

Features

• Intent-driven programmability and streaming telemetry.
• Subsecond access point and client failover for uninterrupted application availability.
• Extraordinary visibility into application traffic, using Cisco Application Visibility and Control (AVC), the technology that includes the Network-Based Application Recognition 2 (NBAR2) engine, Cisco’s Deep Packet Inspection (DPI) capability. This allows to mark, prioritize, and block to conserve network bandwidth and enhance security. Customers can optionally export the flows to Cisco Prime Infrastructure or a third-party NetFlow collector.
• Embedded wireless Bring-Your-Own-Device (BYOD) policy classification engine that allows classification of client devices and application of user group-based policies.
• Deployment of guest access and Bonjour and Chromecast services in centralized deployments.
• Software-defined segmentation with Cisco TrustSec® technology, reducing Access Control List (ACL) maintenance, complexity and overhead.
• Integrated Cisco CleanAir® technology, providing the industry’s only self-healing and self-optimizing wireless network.
• Wi-Fi Alliance Passpoint (Hotspot 2.0) for mobile data offload.
• Network-based mobility management with Proxy Mobile IPv6 Mobility Access Gateway (MAG) and eGRE support for integration with cellular data networks.
• Simplified GUI wizard for quick setup and intuitive dashboards for monitoring and troubleshooting.
• Cisco DNA and SD-Access Wireless, as well as Cisco DNA Assurance.

SD-Access Wireless

SD-Access Wireless is Cisco’s next-generation architecture for enterprise networks. It is the industry’s first policy-based automation from the edge to the cloud. It enables network access in minutes for any user or device to any application without compromising on security. SD-Access Wireless enables policy-based automation for wired and wireless, automated provisioning of wired and wireless networks, group-based policy for users and connected devices, and a distributed wireless data plane for campus deployments. In addition, all clients roams are treated as Layer 2 roams across the network for distributed traffic

Cisco DNA Analytics

Cisco DNA Analytics and Assurance offers comprehensive network visibility. Cisco8540 Wireless Controller Ghana collects data from users, devices, and applications to proactively identify problems. Network analytics and automation help IT quickly resolve issues, so you can increase availability and deliver a better user experience

Scalability and performance
