Do you have POE everywhere?
Do you have POE in every location or are there some small locations that still use injectors? If you have some injectors left, I have a few questions. 1. How reliable are they? 2. Are your injectors made by your wireless vendor? 3. Do you have a way to monitor how often your APs reboot? The reason I'm asking is that I just discovered that we have some APs that are rebooting frequently and they are all in locations that still have injectors. I expanded some home-grown code and started graphing AP uptime as well as lwapp/capwap uptime. (Found issues with lwapp/capwap uptime in a few locations as well) -- Todd M.

Disabling 802.11b speeds
This has been discussed in the past, but it has been a long time. We're at the point that we have to turn off the lower connection rates on our campus. I'm curious what other schools have done and the positive/negative results from the changes. We have disabled 1, 2, 5.5, and 11 Mbps in some of our buildings with great success, but some might argue to just eliminate 1 2 Mbps rates.

Re: [WIRELESS-LAN] Stolen Wireless Device Tracking?
We maintain a mysql database of the mac addresses of stolen devices. We use this to generate a dns config file and use it like a DNS RBL. We use ISC's dhcpd and send the logs to a central log server (syslog-ng). We use SEC to monitor syslog entries in realtime. One of the rules in SEC gets the mac address of every dhcpd query and does a dns query. If it is successful, notification is sent to our security officer as well as me. We then use WCS to find the exact location. We have recovered quite a few notebooks this way. The problem is that most stolen devices are taken off campus and sold on ebay or other online sites. What I would love to see is a central mysql database containing the mac addresses of stolen notebooks from lots of schools. All participating schools could then scan for all the stolen notebooks, not just their own. I think this would lead to a much higher recovery rate for all of us. There are probably legal issues with this concept, but it has potential.

Re: [WIRELESS-LAN] Cisco WiSM
Not sure what you mean by the prolong crash, but when we were running 4.1.x and older code, we had random crashes, sometimes multiple controllers would crash at the same time.

If you think about the classic activity of war-driving, you're typically trying to find wireless networks from within a vehicle, which is largely a rolling Faraday cage- just like a bus. I have external antennas, but rarely bother with them during my often very successful, shall we say, explorations in this area. So perhaps another somewhat simplistic way of looking at the idea of outside-in coverage for rolling busses is that you're setting up a really good war-driving target for passengers (as casual users) to be able to find and use. Seems like even a less-than-optimal WiFi corridor along a 30 MPH or less bus route *may* provide throughputs as good as a cellular-based access point that's at one end of a bus full of signal-attenuating people.

We are running 4.2.61.0 on all our WiSMs and they have been very stable as long as ssh is disabled. We were getting reports of clients that were connected and working one minute and connected and not working the next. We traced the problem down to a failed roam. If we looked the user up in WCS, they would exist on two different controllers at the same time with a protocol of mobile on one of them. The only way we could get them working again was for them to disconnect, wait for 5 minutes and try again (or we could kick both connections off manually). We did some searching and found that lots of users were in this same state at any given time. We enabled symmetric mobility on all our controllers. This solved the problem. Now when a client roams to an AP on a different controller, a tunnel is setup between the anchor controller and the new controller. Roaming is fast and simple.

The User Idle Timeout is responsible for this behavior. You can increase this value from its default of 300s to a higher value. This will keep the (inactive) association active longer. I'm trying to find out from Cisco whether this will preserve L3 roaming for mobile devices that don't issue DHCP renewals effectively.

Re: [WIRELESS-LAN] OK to upgrade to 4.2 for Cisco Wism/WLC code?
We are running 4.2.61 on four WiSM blades with a little over 800 APs and have not had any problems (upgraded in early January). There are some potential issues with Mesh APs so read the documentation carefully before you upgrade. One note: we had an issue with the controllers crashing early on, this was solved by disabling ssh to the controllers. If your controllers are on a public network, this might be an issue. One nice addition to WCS is the ability to monitor and upgrade autonomous APs from within WCS. It works well as long as your APs have a new enough version of IOS.

If the mibs are installed, you can use these... Users per AP interface is as follows: enterprises.airespace.bsnWireless.bsnAP.bsnAPIfTable.bsnAPIfEntry.bsnAPIfPhyTxPowerLevel. Users per WLAN per controller: enterprises.airespace.bsnWireless.bsnEss.bsnDot11EssTable.bsnDot11EssEntry.bsnDot11EssNumberOfMobileStations. Of course, each of these is followed by index values. You can also gather the following information (as well as lots more) Radio channel number Radio transmit power level AP Oper status AP Admion status AP info: name, ethernet mac, location field (we use this to hold inventory info), model, serial number, certificate type. User information: mac address, username, interface used, etc Rogue AP information: ssid, channel, radio type, which internal APs detected it Once all this is stored, you can generate some very useful statistics pages and search pages. For instance, I had a Cisco engineer tell me of a flaw and work around on particular AP model. I can tell where they are in seconds. At a glance, I can see how many APs are on each controller on one page. No more looking at each controller separately in WCS.

Re: [WIRELESS-LAN] lwapp rogue detector mode AP configuration
Rogue Detector Mode is one of the modes an AP can be configured as. Instead of servicing clients, it strictly concentrates on detecting rogue APs. What makes Rogue Detector Mode different than the normal detection process is that in Rogue Detector Mode an AP actually determines if a rogue AP is on the wired network or not. It doesn't help you locate it on the wired network, but it at least determines that it is on the wired network. I got this working by putting the APs uplink port in trunking mode and set its native vlan to the vlan that the AP is usually in. Once I did this, I put the AP in Rogue Detector Mode and after a little while, rogue APs started showing up with a status of Threat instead of Alert in WCS.

Re: [WIRELESS-LAN] Cisco LWAPP
We are using Cisco 2950 switches which do not provide PoE but are PoE aware as far as cdp is concerned. The AP checks the port it is plugged into using cdp to see if the port is capable of providing enough power for the AP. The response from the switch is such that the AP will go into a low power mode (with the radios turned off). You can configure the AP letting it know that it is getting its power via the injector but this gets very annoying when you are upgrading hundreds of APs. We found that if you just disable cdp on the switch port, the AP then assumes that it is getting its power via an injector and turns the radios on. It is not the best solution, but it works.

No master view from WCS of all controllers configurations to compare for uniformity of config We are addressing this internally. We have written scripts to query various configurations via snmp and insert the data into a mysql database. We can then generate reports of potential problems. 3. No wild card searches for clients or APs when searching in WCS You can use % as a wildcard for your searches. It is still not great, but it helps. We have written our own code to help with this too. 4. AP radios come up in transmit, before proper vlan is assigned to them- meaning that clients might associate to a non-functional cell (meaning there might be confusion and help-desk calls) We never noticed this one. 5. No view of the Ethernet port on the AP from the WCS or controller, which means you can't tell if it negotiated speed or duplex correctly We have never needed this. We can always look at the switch port to get this data. 6. ACLs in the WCS have to be built line by line, no copy and edit or text file input 7. MAC address searches have to be colon delimited Correct, AND they are also case sensitive which we found thanks to a cut and paste search for a rogue AP. 8. Mispellings in the WCS GUI, usually on error popups 9. Difficult debugging, like from an AP you have no knowledge of what controller it associated to or tried to associate to If an AP is currently associated with a controller, the controller IP address is shown in WCS if you search pull up a list of APs. I suspect you are talking about APs that don't connect successfully. Early in our migration, we just brought those back to the office and got on the console and watched to see what was happening. This was very helpful. 10. No view from the AP or WCS on what switch and port the AP

Re: [WIRELESS-LAN] Cisco LWAPP
turn off and unless you went in and configured them individually. 11. Inconsistant AP association behavior, certificate issues on converted APs (mostly 1200s) not registeriing with controllers and having to be manually added We upgraded our older APs with the upgrade tool provided by Cisco. This tool would put the self signed certificates on one controller. This worked farily well. We would then have to go into WCS and refresh the WCS config from the controller that had the certificates. Then, in WCS go to controller templates - Security - AP Authorization and the certificates would all be there. These are templates and can then be pushed to all other controllers easily. 12. Converted APs drop their pre-conversion system names and go to mac address for name I don't know any way around this one. 13. No ability for AP groups VLAN templates for multiple controllers 14. Cannot use static WEP and AirFortress clients together on an SSID/VLAN as you can in the autonomous world There are more... and I'm not bashing the product, believe it or not.
