Product Overview

The Cisco® 2500 Series Wireless Controller enables systemwide wireless functions in small to medium-sized enterprises and branch offices. Designed for 802.11n and 802.11ac performance, Cisco 2500 Series Wireless Controllers are entry-level controllers that provide real-time communications between Cisco Aironet® access points to simplify the deployment and operation of wireless networks (Figure 1).

Description: Figure1

As a component of the Cisco Unified Wireless Network, this controller delivers centralized security policies, wireless intrusion prevention system (wIPS) capabilities, award-winning RF management, and quality of service (QoS) for voice and video. Delivering 802.11ac performance and scalability, the Cisco 2500 Series provides low total cost of ownership and flexibility to scale as network requirements grow.

The Cisco 2504 Wireless Controller supports Cisco Application Visibility and Control (AVC), the technology that includes Cisco’s Network-Based Application Recognition 2 (NBAR-2) engine. N-BAR-2 does deep packet inspection (DPI) to classify applications and tie into quality of service (QoS) to either drop or mark the traffic, thereby prioritizing business-critical applications in the network. Cisco AVC uses NetFlow Version 9 to export the flows to Cisco Prime Infrastructure or a third-party NetFlow Collector. The Cisco 2504 Wireless Controller also supports Bonjour Services Directory, which enables Bonjour (Apple) Services to be advertised and utilized in a separate Layer 3 network. Wireless Policy engine is a wireless profiler and policy feature on the Cisco 2500 Series Wireless Controller that enables profiling of wireless devices and enforcement of policies such as VLAN assignment, QoS, ACL, and time-of-day-based access.

Cisco 2500 Series Wireless Controller-based access point licensing offers flexibility with 5, 15, 25, or 50 access points. Additional access point support can be added in increments of 1, 5, or 25.

Table 1 lists the features and benefits of the Cisco 2500 Series Wireless Controllers.

Ease of Deployment

  For quick and easy deployment Access Points can be connected directly to 2504 Wireless LAN Controller via two PoE (Power over Ethernet) ports

High Performance

  Wired-network speed and nonblocking performance for 802.11n and 802.11ac networks. Supports up to 1 Gbps throughput

RF Management

  Provides both real-time and historical information about RF interference impacting network performance across controllers, via systemwideCisco CleanAir® technology integration

Comprehensive End-to-End Security

  Offers CAPWAP-compliant Datagram Transport Layer Security (DTLS) encryption to help ensure full-line-rate encryption between access points and controllers across remote WAN/LAN links

End-to-end Voice

  SupportsUnified Communications for improved collaboration through messaging, presence, and conferencing  Supports allCisco Unified Wireless IP Phones for cost-effective, real-time voice services

High-Performance Video

  Integrates Cisco VideoStream technology as part of the Cisco medianet framework to optimize the delivery of video applications across the WLAN

PCI Integration

  Part of Payment Card Industry (PCI) certified architecture, and are well-suited for retail customers who deploy transactional data applications such as scanners and kiosks

OfficeExtend

  Supports corporate wireless service for mobile and remote workers with secure wired tunnels to the Cisco Aironet® 600, 1130, 1140 or 3500 Series Access Points  Extends the corporate network to remote locations with minimal setup and maintenance requirements  Improves productivity and collaboration at remote site locations  Separate service set identifier (SSID) tunnels allow both corporate and personal Internet access  Reduced carbon dioxide emissions from a decrease in commuting  Higher employee job satisfaction from ability to work at home  Improves business resiliency by providing continuous, secure connectivity in the event of disasters, pandemics, or inclement weather

Enterprise Wireless Mesh

  Allows access points to dynamically establish wireless connections without the need for a physical connection to the wired network  Available on select Cisco Aironet access points, Enterprise Wireless Mesh is ideal for warehouses, manufacturing floors, shopping centers, and any other location where extending a wired connection may prove difficult or aesthetically unappealing

Environmentally Responsible

  Organizations may choose to turn off access point radios to reduce power consumption during off-peak hours

Mobility, Security and Management for IPv6 & Dual-Stack Clients

  Secure, reliable wireless connectivity and consistent end-user experience  Increased network availability by proactive blocking of known threats  Equips administrators for IPv6 troubleshooting, planning, client traceability from a common wired and wireless management system

Guest Anchor and Wired Guest Access

  Supports up to 15 guest anchor Ethernet over IP (EoIP) tunnels forpath isolation of guest traffic from enterprise data traffic  Extends the guest access services to the wired clients on par with other WLAN Controllers
