Security and Authentication Options

The AIR-CT5520-K9 Cisco 5520 Wireless LAN Controller provides various security and authentication options to ensure that wireless networks are secure and only authorized users have access. Here are some of the key security and authentication features of the controller:

• WPA2 and 802.11i Security Standards: The controller supports the latest security standards, including WPA2 and 802.11i, which provide robust encryption and authentication for wireless networks.
• 802.1X Authentication: The controller supports 802.1X authentication, which requires users to provide credentials before they can access the wireless network. This helps to ensure that only authorized users can connect to the network.
• MAC Address Filtering: The controller can be configured to only allow specific MAC addresses to connect to the wireless network. This helps to prevent unauthorized devices from accessing the network.
• Captive Portal: The controller can be configured to use a captive portal, which requires users to provide credentials or accept the terms and conditions of use before they can access the network. This is a useful feature for guest networks.
• RADIUS Authentication: The controller can integrate with RADIUS servers for authentication, which provides centralized management of user credentials and access control.
• Wireless Intrusion Prevention System (wIPS): The controller includes a wIPS system that can detect and mitigate wireless threats and attacks, such as rogue access points, denial-of-service attacks, and man-in-the-middle attacks.

By providing these security and authentication options, the AIR-CT5520-K9 controller helps to ensure that wireless networks are secure and only authorized users have access. IT administrators can use these features to manage and control access to the network, prevent unauthorized devices from connecting, and detect and mitigate wireless threats and attacks.

High Availability and Redundancy Options

The AIR-CT5520-K9 Cisco 5520 Wireless LAN Controller provides high availability and redundancy options to ensure continuous operation of the wireless network. Here are some of the high availability and redundancy options available:

• Stateful Switchover (SSO): SSO allows for seamless failover to a standby controller in the event of a primary controller failure. The standby controller is continuously synchronized with the primary controller, so when a failover occurs, there is no loss of data or disruption to service.
• Hot Standby: Hot standby provides an immediate failover mechanism to a backup controller, which is always active and continuously synchronized with the primary controller. This option provides an additional level of redundancy and reduces the risk of downtime.
• Redundant Power Supplies: The AIR-CT5520-K9 controller has the option for redundant power supplies to ensure continuous operation even in the event of a power supply failure.
• Redundant Network Connections: The controller has multiple Ethernet ports, which can be used to connect to different switches, providing redundancy in case of network failures.
• Virtual Port-Channel (vPC): vPC is a technology that provides redundancy and load balancing for Ethernet connections. The AIR-CT5520-K9 controller supports vPC, which allows for multiple connections to be active simultaneously for added redundancy and load balancing.

By providing high availability and redundancy options, the AIR-CT5520-K9 controller ensures that the wireless network remains operational even in the event of a failure. IT administrators can configure these options to meet their specific requirements and ensure maximum uptime for the wireless network.

Advanced Multicast and Bonjour Configuration

The AIR-CT5520-K9 Cisco 5520 Wireless LAN Controller provides advanced multicast and Bonjour configuration options to help IT administrators manage and control multicast traffic and enable Bonjour-enabled services in wireless networks. Here's a brief explanation of each:

• 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-CT5520-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.
• 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.
• Advanced Multicast Configuration: The AIR-CT5520-K9 controller provides advanced multicast configuration options to help manage and optimize multicast traffic in wireless networks. The controller can be configured to manage multicast traffic using advanced features such as IGMP snooping and multicast group filtering.
• Advanced Bonjour Configuration: The controller provides advanced Bonjour configuration options to help manage and control Bonjour traffic in wireless networks. The Bonjour policies can be configured to control the behavior of Bonjour traffic, including defining which services are available on which VLANs and filtering Bonjour services.

By providing advanced multicast and Bonjour configuration options, the AIR-CT5520-K9 controller helps to ensure that wireless networks are optimized for efficient and reliable data delivery, and that Bonjour-enabled services are available across subnets. IT administrators can use these features to manage and control multicast and Bonjour traffic, and ensure that wireless networks are optimized for the best possible user experience.
