Product Bulletin No. 3519

Discontinuation of Support for Wireless Domain Services
on Cisco 2600XM/2691/3700 Series Multiservice Routers and
Cisco 2800 and 3800 Series Integrated Services Routers

This product bulletin serves as a notification of the discontinuation of support for the Wireless Domain Services

(WDS) Fast Secure Roaming feature on the Cisco

2600XM/2691/3700 Series Multiservice routers and Cisco 2800

and 3800 Series Integrated Services Routers running Cisco IOS

Software images later than Release 12.3(14)T.

DESCRIPTION

The Fast Secure Roaming feature provides the capability for client devices to roam from one access point to another without requiring

reauthentication by the main RADIUS server. By streamlining the roaming process, this feature supports client applications, such as voice

over IP (VoIP), that require seamless roaming to avoid delays and gaps in transmission. This feature is supported on Cisco Aironet

Access

Points and the Cisco Catalyst

6500 Series Wireless LAN Services Module (WLSM) and was integrated into Cisco IOS Software Release

12.3(11)T for the Cisco 2600XM, 2691, 3700, 2800, and 3800 routers. Access points and the Cisco Catalyst 6500 Series WLSM still

support Fast Secure Roaming; however, support for this feature on the wireless-aware routers is discontinued. This feature is supported

only in the scenario summarized in Table 1.

at a later date.

Feature Limitations

WDS support on the Cisco 2600XM, 2691, 3700, 2800, and 3800 routers is limited to Layer 2 Fast Secure Roaming with the releases

listed in Table 1. Radio management, CiscoWorks Wireless LAN Solutions Engine (WLSE) interaction, and new features released after

Cisco IOS Software Releases 12.3(14)T and 12.2(11)JA are not supported. For full WDS support, including Layer 2 Fast Secure Roaming,

radio management, and CiscoWorks WLSE interaction, please choose one of the alternative solutions described in the following section.
