The AIR-CT2504-15-K9 is a Cisco 2500 series wireless LAN controller that provides centralized management and control of wireless access points. Network Access Control (NAC) is an important aspect of securing wireless networks, and the AIR-CT2504-15-K9 supports a variety of NAC features to help ensure secure access.

Here are some key NAC features and security measures supported by the AIR-CT2504-15-K9:

• 802.1X Authentication: The controller supports 802.1X authentication, which requires users to provide valid credentials before they can connect to the wireless network. This helps prevent unauthorized access and ensures that only authorized users can connect.
• Guest Access: The controller also supports guest access, which allows guests to connect to the network without requiring them to provide valid credentials. However, the controller can limit guest access to certain resources and provide a separate VLAN for guest traffic to help prevent unauthorized access to sensitive resources.
• MAC Address Filtering: The controller can also restrict access based on MAC addresses, which can help prevent unauthorized access from devices that are not approved to connect to the network.
• Rogue AP Detection: The controller can detect rogue access points that are not authorized on the network, which can help prevent unauthorized access and mitigate security threats.
• Wireless Intrusion Prevention System (WIPS): The controller also supports WIPS, which can detect and prevent a variety of wireless security threats, including rogue access points, denial-of-service attacks, and malware.
• Security Certificates: The controller supports the use of security certificates to help ensure secure communication between the controller and wireless access points, as well as between the controller and other network devices.
• In addition to these NAC features and security measures, the AIR-CT2504-15-K9 also supports other security measures, such as network segmentation, access control lists (ACLs), and encryption. These measures can help ensure that only authorized users and devices can access the network and that data transmitted over the network is secure.

The Cisco 2500 Series Wireless LAN Controller (WLC) provides centralized management and control for wireless access points (APs) in a wireless LAN (WLAN). Here are the steps to manage the wireless LAN using the AIR-CT2504-15-K9 Cisco 2500 Series Wireless LAN Controller:

• Configure the Wireless LAN Controller: The first step in managing the wireless LAN is to configure the WLC. This includes setting up the WLC's IP address, hostname, and time zone, and configuring the WLC's management interface.
• Configure WLANs: Next, you can configure WLANs on the WLC. This includes defining the SSID, configuring security settings (e.g., WPA2, 802.1X), and configuring access policies (e.g., guest access, employee access).
• Configure Access Points: Once the WLANs are configured, you can add APs to the WLC. This includes discovering the APs on the network, configuring the APs' settings (e.g., power, channel, antenna), and associating the APs with the WLANs.
• Monitor and Troubleshoot the WLAN: The WLC provides several tools to monitor and troubleshoot the WLAN. This includes using the WLC's dashboard to view WLAN statistics (e.g., number of clients, throughput), monitoring logs for WLAN-related events, and using diagnostic tools (e.g., ping, traceroute) to troubleshoot connectivity issues.
• Manage Software Upgrades: To ensure that your WLC software is up-to-date and secure, you can use the WLC's software upgrade feature to upgrade the WLC firmware and AP firmware.
• Configure Advanced Features: The WLC provides several advanced features, such as a wireless intrusion prevention system (WIPS), quality of service (QoS), and mobility. You can configure these features to enhance the security, performance, and mobility of the WLAN.
