The Cisco Wireless LAN can help reduce your risk of hackers or malicious users gaining access to critical network resources. The two controllers we are highlighting today enable system-wide wireless functions in small to medium-sized enterprises and branch offices. Control can be maintained throughout the whole organization by lightweight wireless access points from the controller and changes can be applied within minutes if need be. They're designed for 802.11n and 802.11ac performance, and the controllers can simultaneously act as data-serving devices and IDS sensors.
Today, we are diving back into the 2504 and 3504 Wireless LAN Controllers. Though, 2504 is no longer sold directly by Cisco the support for this controller until 2023. Don't let these dates get in the way of you achieving your goal. Let OneCall, PivIT's maintenance offering, cover your 2504 or 3504 devices. Connect with our team to see if this would be a good fit for your network.
Below, we'll give a high-level overview of each controller and place them side-by-side to see which fits best in your network! Let's dive in.
Cisco 2504 Wireless LAN Controller
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 CiscoPrime™ Infrastructure or to 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.
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
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 overall carbon dioxide emissions from a decrease in commuting
PCI Integration and End-to-End Voice
The 2504 Wireless Controller is Part of Payment Card Industry (PCI) certified architecture and is well-suited for retail customers who deploy transactional data applications such as scanners and kiosks. It supports Unified Communications for improved collaboration through messaging, presence, and conferencing. The controller also supports all Cisco Unified Wireless IP Phones for cost-effective, real-time voice services.
Cisco 3504 Wireless LAN Controller
Optimized for 802.11ac Wave 2 performance, the 3504 Wireless Controller is compact, highly scalable, and flexible enabling next-generation wireless networks. This controller fits best in small to medium-sized enterprises along with branch office deployments. The 3504 is a versatile controller with support for centralized, distributed, and mesh deployments to be used at different places.
Cisco DNA SD-Access, Analytics, and Assurance
The 3504's 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.
Along with the SD-Access, the 3504 has Cisco DNA Analytics and Assurance offering comprehensive network visibility. It 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.
Fault Tolerance and High Availability
- Sub-second access point and client failover for uninterrupted application availability
- Redundant 1 Gigabit Ethernet or Cisco Multigigabit Ethernet (up to 5 Gigabit Ethernet) connectivity
- Solid-state device-based storage—no moving parts
