I've got a little command-line tool for windows XP that configures the WZC
supplicant. It is home-grown.  Please e-mail me off-line if you would like
to try it.  Soon, however, I'll have something that is publicly consumable.

Subject: [WIRELESS-LAN] Dynamic WEP transition to WPA

All,

I'm interested to hear any experiences/thoughts on transitioning from
Dynamic WEP to WPA encryption, especially from those of you with "Fat" Cisco
AP deployments.

I see a few options, none of which I'm convinced is the way to go.

1) Announce a cutover date, after which Dynamic WEP will cease to work and
everyone must use to WPA.

Pros: relatively easy config change, clean compatibility cut off
Cons: potential for a LOT of help desk work that day/week...

2) Announce a cutover period, where both operate for a time (using Cisco's
WEP 128 + TKIP migration mode), after which only using WPA.

Pros: Gives people a chance to reconfigure on their own schedule
Cons: Mac 10.3 seems unable to connect to APs in this migration mode, but IS
fine with just WPA, other clients may also have this problem, not sure what
to do with them during the migration period.

3) Deploy a new SSID/VLAN, announce a cutover period, after which shutdown
the old one.

Pros: Gives people a chance to reconfigure on their own schedule
Cons: A LOT more back-end work, I'll miss our current ssid, go (cavalier)s!


Has anyone gone down one of these paths?  Come up with others?  Any WPA
compatibility horror stories?

-Keith

p.s. Switching to a different wireless platform is not an option at this
point, I realize this could be easier with <insert vendor  
here>'s amazing product.
