Cisco 2100 Series Wireless LAN Controllers

Cisco Wireless LAN Controller Software Organization Structure

Downloads

PB454127

Cisco® announces changes to the organization of the Cisco Wireless LAN Controller software releases on the Cisco.com Wireless Software download page.
Cisco has organized the software releases of the wireless LAN controllers for the Cisco Unified Wireless Network to better differentiate software releases and allow customers to choose the appropriate software release. These changes have been updated in the Cisco Software Center (Cisco.com) and will be adhered to from now on.

Previous Software Structure

Previously, the software releases for the wireless LAN controllers were displayed in two categories: Latest Releases and All Releases. This method has been confusing for some customers who need assistance in choosing which software release they should deploy.

Figure 1. Previous Software Structure

New Software Structure

The software releases will now be organized into the following categories: Early Deployment Releases, Maintenance Releases, and Deferred Releases.

Figure 2. New Software Structure

Table 1 describes the new software release structure for the Cisco Unified Wireless Network. This organizational structure is valid on standalone, wireless integrated routers, and wireless integrated switches. Included are the latest controllers such as the Cisco 2100 and 4400 Series Wireless LAN Controllers; the Cisco Catalyst® 6500 Series Wireless Services Module (WiSM); the Cisco Wireless LAN Controller Module (WLCM) and Cisco Wireless LAN Controller Module Enhanced (WLCM-E) for integrated services routers; and the Cisco Catalyst 3750G Integrated Wireless LAN Controller.

Maintenance releases

These software releases define I/O releases that provide bug-fix support and ongoing software maintenance: they are categorized as Maintenance Deployment (MD) and may be part of the AssureWave program.*

*AssureWave is a Cisco program that focuses on satisfying customer quality requirements in key vertical markets in the mobility space. This program links and expands on product testing conducted within development engineering, regression testing, and systems test groups within Cisco. The AssureWave program has established partnerships with major device and application vendors to help ensure broader interoperability with our new release. The AssureWave certification marks the successful completion of extensive wireless LAN controller and access point testing that validates targeted releases.
