Chapter 6 Troubleshooting Lightweight Access Points

Returning the Access Point to Autonomous Mode

Returning the Access Point to Autonomous Mode

You can return a lightweight access point to autonomous mode by loading a Cisco IOS release that supports autonomous mode (such as Cisco IOS Release 12.3(8)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.

Using a Controller to Return the Access Point to Autonomous Mode

Follow these steps to return a lightweight access point to autonomous mode using a controller:

Step 1 Log into the CLI on the controller to which the access point is associated and enter this command:

config ap tftp-downgradetftp-server-ip-address filename access-point-name (where:

a)tftp-server-ip-addressis the IP address of the TFTP server

b)filename is the full path and filename of the access point image file, such as D:/Images/c1100-k9w7-tar.123-8.JA.tar

c)access-point-nameis the name that identifies the access point on the ocntroller.)

Step 2 Wait until the access point completes the reboot, as indicated by the Status LED turning green to indicate a client is associated or blinking green to indicate a client is not associated.

Step 3 After the access point reboots, reconfigure it using the access point GUI or the CLI. For additional information refer to the Cisco Aironet 1100 Series Access Point Hardware Installation Guide available at this URL:

Using the MODE Button to Return the Access Point to Autonomous Mode

Follow these steps to return a lightweight access point to autonomous mode using the access point MODE button and a TFTP server:

 

Note

The access point MODE button is enabled by default, but you need to verify that the MODE button is

 

 

enabled (see the “MODE Button Setting” section on page 6-6).

 

 

 

 

 

 

 

Step 1

Set the static IP address of the PC on which your TFTP server software runs to an address between

 

 

10.0.0.2 and 10.0.0.30.

 

Step 2

Make sure that the PC contains the access point image file (such as c1100-k9w7-tar.123-8.JA.tar for a

 

 

1100 series access point) in the TFTP server folder and that the TFTP server is activated.

 

Step 3

Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default.

 

Step 4

Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

 

Step 5

Disconnect power from the access point.

CSACS1121K9 specifications

Cisco Systems CSACS1121K9 is a part of Cisco's comprehensive suite of security solutions tailored for identity and access management. This device, recognized for its reliability and functionality, plays a crucial role in ensuring that organizations can efficiently manage user access across their networks.

One of the main features of the CSACS1121K9 is its centralized user authentication capabilities. This device simplifies the process of validating user identities, allowing administrators to manage credentials for a variety of access methods, including web-based authentication, RADIUS, and TACACS+. This flexibility plays a significant role in diverse environments where different protocols may be required for various devices or applications.

The CSACS1121K9 is built on the robust Cisco Secure Access Control Server (ACS) platform. This platform supports a wide range of security policies, making it versatile enough for different organizational needs. With its capability to integrate seamlessly with other Cisco solutions and third-party platforms, the device enhances the overall security posture of an organization.

In terms of scalability, the CSACS1121K9 can support a substantial number of users and devices. This scalability ensures that as organizations grow, their access management system can scale proportionately without performance degradation. The ability to handle thousands of simultaneous authentication requests makes it suitable for both small companies and large enterprises.

Another significant characteristic of the CSACS1121K9 is its support for advanced visibility and reporting. Administrators can track authentication attempts, policy enforcement, and other critical events in real time. This level of monitoring is essential for compliance audits and helps organizations quickly react to potential security threats.

Moreover, the CSACS1121K9 includes capabilities for implementing role-based access control (RBAC). This feature allows organizations to define specific access rights based on user roles, which enhances security while facilitating efficient operations.

In conclusion, the Cisco Systems CSACS1121K9 is a powerful tool for organizations seeking to enhance their identity and access management frameworks. With its centralized user authentication, scalability, advanced reporting capabilities, and support for RBAC, it provides a robust solution that can adapt to the evolving security demands of modern networks. Whether deployed in a small business environment or within large enterprises, the CSACS1121K9 stands out for its comprehensive feature set and ability to integrate into existing security infrastructures.
