AIR-CT2504-50-K9 Cisco 2504 Wireless LAN Controller Refurbished

Quality of Service and Traffic Management

The AIR-CT2504-50-K9 Cisco Aironet CT2504 Wireless LAN Controller provides advanced Quality of Service (QoS) and traffic management features to ensure that the wireless network delivers the performance and reliability needed to support critical applications and services.

Here are some of the QoS and traffic management features available with the AIR-CT2504-50-K9:

• Wireless Multimedia (WMM): The controller supports WMM, a QoS mechanism that prioritizes traffic based on its type and priority level. WMM can help ensure that applications that require low latency and high throughput, such as voice and video, receive the necessary bandwidth and are not impacted by other traffic on the network.
• Bandwidth Management: The controller provides bandwidth management features that allow administrators to control the amount of bandwidth that is allocated to specific users, devices, or applications. This can be useful in environments where network resources are limited, and administrators need to ensure that critical applications receive the necessary bandwidth.
• Admission Control: The controller supports admission control, which allows administrators to restrict access to the network based on specific criteria, such as the number of concurrent clients or the bandwidth requirements of the client devices. Admission control can help ensure that the network is not overloaded and that critical applications receive the necessary resources.
• Traffic Shaping: The controller provides traffic shaping features that allow administrators to control the rate of traffic that is sent and received on the network. This can be useful in environments where network resources are limited, and administrators need to ensure that critical applications receive the necessary bandwidth.
• Application Visibility and Control: The controller provides visibility into the types of applications and services that are being used on the network. This information can be used to identify and prioritize critical applications, as well as to block or limit the use of non-critical applications.

By providing advanced QoS and traffic management features, the AIR-CT2504-50-K9 Cisco Aironet CT2504 Wireless LAN Controller ensures that the wireless network delivers the performance and reliability needed to support critical applications and services. Whether deploying a small or large-scale wireless network, the controller provides the flexibility and control needed to ensure that the network runs smoothly and efficiently.

The AIR-CT2504-50-K9 Cisco Aironet CT2504 Wireless LAN Controller is designed to provide centralized management and control for up to 50 Cisco Aironet access points. To ensure high availability and minimize downtime, the controller offers several redundancy and failover options.

Here are some of the high availability and redundancy options available with the AIR-CT2504-50-K9:

• Redundant Power Supply: The controller supports a redundant power supply option, which provides a second power supply in case the primary power supply fails.
• Redundant Controllers: The AIR-CT2504-50-K9 can be deployed in a high availability configuration, where two controllers are deployed in a primary-secondary configuration. If the primary controller fails, the secondary controller takes over, ensuring that the wireless network remains available.
• Virtual PortChannel: The controller supports Virtual PortChannel (vPC) technology, which allows for redundancy in the upstream network switches. vPC provides a redundant path for traffic to reach the controller and ensures that traffic is load balanced across both paths.
• Hot Standby Mode: The controller supports a Hot Standby Mode, which allows for automatic failover in case of a controller failure. When Hot Standby Mode is enabled, a secondary controller is designated as the hot standby and is ready to take over if the primary controller fails.
• Stateful Switchover: The controller supports Stateful Switchover (SSO), which is a high availability feature that provides non-stop forwarding during a supervisor engine switchover. SSO allows the controller to maintain the state of the network during a switchover and ensure that the wireless network remains available.

By offering a range of redundancy and failover options, the AIR-CT2504-50-K9 provides a highly available and reliable wireless network. Whether deploying a small or large-scale wireless network, the controller provides the flexibility and control needed to ensure that the network runs smoothly and with minimal downtime.

The AIR-CT2504-50-K9 Cisco Aironet CT2504 Wireless LAN Controller provides Bonjour Gateway and Multicast Configuration options that allow IT administrators to manage and control multicast traffic in wireless networks. Here's a brief explanation of each:

• Bonjour Gateway: The Bonjour Gateway feature enables users to discover and access Bonjour-enabled services, such as printers and Apple TV, over a wireless network. The Bonjour Gateway works by translating Bonjour multicast packets into unicast packets, which can be forwarded across subnets. This feature helps to enable cross-subnet Bonjour services without the need for additional configuration.
• Multicast Configuration: Multicast is a technology used to send data to multiple recipients simultaneously. In wireless networks, multicast is often used for media streaming applications, such as IPTV and digital signage. The AIR-CT2504-50-K9 controller provides multicast configuration options to help manage and control multicast traffic in wireless networks. The controller can be configured to manage multicast traffic in various ways, such as limiting the number of multicast streams, configuring multicast group addresses, and setting up multicast rate limits.

By providing Bonjour Gateway and Multicast Configuration options, the AIR-CT2504-50-K9 controller helps to improve the user experience and ensure the smooth operation of multicast applications over wireless networks. IT administrators can use these features to manage and control multicast traffic and ensure that wireless networks are optimized for efficient and reliable data delivery.
