Cisco 2800 and 3800 Series Integrated Services Routers
on Cisco 2600XM/2691/3700 Series Multiservice Routers and

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.

Customers wanting to use Fast Secure Roaming on routers must continue to use the combination listed in Table 1. The Cisco Technical
Assistance Center (TAC) does not support other software releases. The WDS Fast Secure Roaming configuration commands may be found
in later releases; however, they will be removed from the Cisco IOS Software on the Cisco 2600XM, 2691, 3700, 2800, and 3800 routers
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.
