Introduction
What is WDS?
How do I configure my AP as a WDS?
On what platforms does Cisco Structured Wireless−Aware Network (SWAN) WDS run?
How does AP−based WDS compare with switch−based WDS?
How do I set up WDS with my current wireless LAN (WLAN) network?
What is the role of the WDS device in the wireless LAN (WLAN) network?
How do the WDS and the infrastructure APs in the WLAN communicate with each other?
Can I configure the 1300 AP/Bridge as a WDS master?
How many infrastructure APs can a single WDS manage?
What is fast secure roaming (FSR)?
What is Layer 3 (L3) roaming?
What is the role of the Wireless LAN Solution Engine (WLSE) in a WDS−enabled wireless LAN (WLAN)
network?
What are the advantages of the use of WDS on a Wireless LAN Services Module (WLSM)?
What is the radio management (RM) feature of WDS?
Can Cisco Aironet APs support clients while the APs scan the air/radio frequency (RF) environment?
Can WDS perform accounting functions?
In order to set up WDS with CCKM what are the cipher suites supported? Is Extensible Authentication
Protocol−Flexible Authentication through Secured Tunnel (EAP−FAST) compatible with Cisco CKM? What
combination do I use?
Does the authentication key−management cckm optional command work for both Aironet clients with fast
roaming checked and those without fast roaming checked?
For how long does the WLSM cache user credentials?
Can I set up more than 60 APs in a WDS that uses AP−based WDS?
How many WDS backup candidates can I have? Can a WDS backup candidate still function as an AP in the
WDS and report the information to the primary WDS?
If I have three WDS APs and they all fail, does the failure only affect WDS information, or all APs and
clients? In other words, is the WDS a point of failure for the wireless network?
On one subnetwork, I have a WDS configured with a priority of 200 and a WDS with a priority of 100. If the
WDS master with a priority of 200 fails, does the WDS with the priority of 100 become the master on the
subnetwork?

show iapp rogue−ap−list
command in a Cisco 1200 AP provide any useful information
when a Wireless LAN Solution Engine (WLSE) is not in place?
I have a Cisco AP1200 configured for WDS. The AP hangs and does not respond on the console or Telnet
until I perform a power cycle. However, the AP does not crash. Why does this happen?
Can a repeater AP support WDS?
Can a 350 series AP be configured as WDS access point?
