Has the WLSE been replaced?

Unanswered Question
Aug 13th, 2007

I haven't installed or priced a wireless system in a while and now cant find pricing for the WLSE. What replaced it for 6 AP control. They are getting 7921 IP Phones for this setup and I would like to use te WLSE for seamless roaming.

I have this problem too.

Hi Todd,

The WLSE has not been completly "End of Life" although I think its safe to say that Cisco is really promoting the change to LWAPP. They even have a migration path from the WLSE to WCS in place. There are many Autonomous AP's that can be converted to LWAPP as well. You probably want to look into one of smaller versions of the WLC (Wireless Lan Contoller) Have a look;

CiscoWorks Wireless LAN Solution Engine (WLSE)

End-of-Life and End-of-Sale Notices

From this doc;

http://www.cisco.com/en/US/products/sw/cscowork/ps3915/prod_eol_notices_list.html

WLSE 2.11 End of Support April 19, 2010 (So if WLSE 2.13 has not yet been EOL then it is safe to say it will be sometime sooner rather than later)

Conversion of a WLSE Autonomous Deployment to a WCS Controller Deployment

http://www.cisco.com/en/US/products/ps6305/products_configuration_guide_chapter09186a00806b71db.html

Customers that have purchased the CiscoWorks WLSE are encouraged to transition to the Cisco WCS and the Cisco Unified Wireless Network. Customers can use the CiscoWorks WLSE to Cisco WCS conversion CDs (Cisco WCS SKU Family WCS-WLSE-UPG-K9) to convert an existing CiscoWorks WLSE (Model 1130-19 and 1133) to operate as a Cisco WCS server.

OK, Thanks for the update. For 6 AP's, I can probably get away with WDS and LEAP for the phones and not worry about a controller. The budget is tight for this customer, and they may not go for it. It looks like there is an NM for a 2811 that supports 6 AP's, so I will look at that and price it out for them.

Could U share withe how to configure WDS. I have 100 over ap. and I trying to make use of some AP as WDS .. I use it auto search... what is your advice, New bie. Thanks

Hi Mcnaz,

Here is some info on the role of WDS.

Configuring WDS, Fast Secure Roaming, and Radio Management

Understanding WDS

When you configure Wireless Domain Services on your network, access points on your wireless LAN use the WDS device (either an access point or a switch configured as the WDS device) to provide fast, secure roaming for client devices and to participate in radio management. If you use a switch as the WDS device, the switch must be equipped with a Wireless LAN Services Module (WLSM). An access point configured as the WDS device supports up to 60 participating access points. A WLSM-equipped switch supports up to 300 participating access points.

Fast, secure roaming provides rapid reauthentication when a client device roams from one access point to another, preventing delays in voice and other time-sensitive applications.

Access points participating in radio management forward information about the radio environment (such as possible rogue access points and client associations and disassociations) to the WDS device. The WDS device aggregates the information and forwards it to a wireless LAN solution engine (WLSE) device on your network.

Role of the WDS Device

The WDS device performs several tasks on your wireless LAN:

Advertises its WDS capability and participates in electing the best WDS device for your wireless LAN. When you configure your wireless LAN for WDS, you set up one device as the main WDS candidate and one or more additional devices as backup WDS candidates. If the main WDS device goes off line, one of the backup WDS devices takes its place.

Authenticates all access points in the subnet and establishes a secure communication channel with each of them.

Collects radio data from access points in the subnet, aggregates the data, and forwards it to the WLSE device on your network.

Registers all client devices in the subnet, establishes session keys for them, and caches their security credentials. When a client roams to another access point, the WDS device forwards the client's security credentials to the new access point.

Participating Access Points Supported by WDS Devices

Access point that also serves client devices

30AP's

Access point with radio interfaces disabled

60AP's

WLSM-equipped switch

300AP's

Role of Access Points Using the WDS Device

The access points on your wireless LAN interact with the WDS device in these activities:

Discover and track the current WDS device and relay WDS advertisements to the wireless LAN.

Authenticate with the WDS device and establish a secure communication channel to the WDS device.

Register associated client devices with the WDS device.

Report radio data to the WDS device.

Here are some good getting started type docs;
