High Performance

The Cisco AIR-CT2504-25-K9 Cisco 2500 Series Wireless Controller is a high-performance wireless controller designed for medium to large enterprise networks. It supports up to 25 access points and can manage up to 500 wireless clients.

The controller offers advanced features such as real-time monitoring, troubleshooting, and reporting capabilities. It also supports multiple wireless standards, including 802.11a/b/g/n/ac, and can be configured to support multiple SSIDs and VLANs.

In terms of performance, the Cisco 2500 Series Wireless Controller offers fast and reliable wireless connectivity. It supports high-speed data transfer rates and can handle a large number of wireless clients without any significant drop in performance. The controller also supports Quality of Service (QoS) features, which allows administrators to prioritize traffic and ensure that critical applications receive the necessary bandwidth.

Additionally, the controller supports robust security features, including WPA2-Enterprise, RADIUS authentication, and Access Control Lists (ACLs) to secure wireless communications.

Power and Innovation 4 Ports LAN Controller

The Cisco AIR-CT2504-25-K9 2500 Series Wireless Controller is a powerful and innovative device that is designed to manage and control wireless networks. It is a centralized platform that allows administrators to configure, monitor, and troubleshoot wireless networks from a single location.

One of the key features of the Cisco product is its ability to support up to 25 lightweight access points (LAPs) at a time. This allows for a large number of wireless devices to be connected to the network at once, making it ideal for large-scale deployments in busy environments such as airports, universities, and corporate offices.

Another major advantage of the Cisco part is its flexibility. It can be deployed in a variety of different network topologies, including standalone, redundant, and hierarchical. This allows administrators to choose the configuration that best suits their network needs.

The Cisco model also offers a number of advanced security features to protect wireless networks from unauthorized access and attacks. These include support for WPA2-Enterprise, RADIUS, and TACACS+ authentication, as well as support for Cisco Identity Services Engine (ISE) and Cisco Secure Access Control Server (ACS) for advanced security management.

Resiliency and High Availability

The AIR-CT2504-25-K9 Cisco 2500 Series Wireless Controller is designed to provide resiliency and high availability for wireless networks. This controller offers several features to ensure that wireless networks remain up and running even in the event of a failure or outage.

  • Redundancy: The controller supports dual-redundancy, allowing for automatic failover in the event of a primary controller failure. This ensures that wireless networks remain operational even in the event of a failure.
  • Load Balancing: The controller supports load balancing, which allows for the distribution of wireless clients across multiple access points. This ensures that wireless networks remain operational even in the event of a high number of clients or high traffic.
  • Backup Power: The controller supports backup power options, such as an optional external power supply, to ensure that wireless networks remain operational even in the event of a power outage.
  • Automatic Failover: The controller supports automatic failover, which allows for automatic switching to a secondary controller in the event of a primary controller failure. This ensures that wireless networks remain operational even in the event of a failure.
  • Network Resilience: The controller supports network resilience, which allows for wireless networks to remain operational even in the event of a network outage. This is achieved through the use of multiple controllers, which can be configured to provide redundancy and failover.
