We had to do this across campus with any AP connected to a 3550 or 2950

I actually wrote a script that would telnet to our controllers, get the
AP status and send the power injector command if need be.

We see about the same as everyone else.
One thing to make sure you do is to prune the trunks to the WiSMs to
eliminate any unnecessary broadcast traffic. I have seen that cause
undue stress on the WiSMs before.

I would be interested in this as well. Right now I am using a PERL
script in conjunction with MRTG to graph our CPU usage. The script uses
telnet to pull the current CPU usage from the WiSMs.
I am willing to share this, but it does require the Net::Telnet::Cisco
PERL module to be installed.
What specific issues have people seen with upgrading WCS to 4.2?
One of our admins is trying to do the upgrade right now, and the install
seems to be getting stuck at the sql upgrade script.

WiSMs have been well tested with SXF code, so unless you have a reason

Just f.y.i.
This is somewhat unrelated, but beware upgrading your SUP's to

We ran into similar problems with this configuration. The WiSM wouldn't
allow a DHCP broadcast to propagate through the controller, it HAD to
relay the request somewhere. Bluesocket HAS to see a DHCP BROADCAST in
order to build a client session, so the WiSM/Bluesocket configuration is
a dicey one.
We experienced a similar issue with our WiSMs, but the issue did not
turn out to be the SUP720. It was actually an issue with our WSX-6548
line card. Access to any host/server connected to the line card was
extremely slow. Cisco narrowed it down to a CEF/Fabric issue with the
card, we swapped the

We have seen something similar. We have about 750 1131's connected to 4

We are in the same process as you. We have 3 WiSM blades and WCS, + ~500

Title: Re: [WIRELESS-LAN] Cisco LWAPP
We actually installed 4.0 on a new box and
just pulled the configs off of the controllers again without any problems. But
we were told by Cisco that you should not run a newer ver of WCS with an older
ver of the WiSM code, or vice versa.
Under the SSID setting there is a session timeout value. By default I
believe that it is 0, you may want to check that. To me a 0 indicates
that the feature is disabled, but it may also indicate a default
behavior, which could be a forced re-authentication after 14,400 seconds
(4 hours).
