Aironet 1200 fragmentation problems?

We have a linux (poptop) PPTP server, and after a while, server starts to discard GRE packets.
Clients are connnected through Cisco AP, and I'm thinking about that something is wrong with MTU and/or MSS on it. With our other APs everything works just fine (linksys, pheenet, ovislink)...
Any ideas?
Thanks in advance!

7921 and aironet 1200 problem

I have set up a network consist of 2 7921 wireless phones and an aironet 1200 AP. I'm able to scan the network and get connected to the network using my laptop, however, the wireless phones keep prompting 'Locating Network Services' then 'Connection Failed'. My aironet 1200 is running on 802.11G. Is there any steps that I have miss out or is there any competability issue between aironet 1200 and 7921 wireless phones.thanks =]

something is wrong with your flash...you could try to blow it out and install IOS, if the AP will allow you to perform the ctrlZ function during startup. Since you have a VX works code 11.42 the Mode button doesn't work yet.
Read this
http://www.cisco.com/en/US/products/hw/wireless/ps430/products_tech_note09186a008019fea0.shtml#without
and see if this works for you. you will need the 'Upgrade to IOS image v.3' first and then you go from there to a flavor of IOS.
It's an arduous process and may not work anyway, so time might be more important that buying another AP, but give it a shot...

Getting started with aironet 1200 and radius

Hi,
Does anyone has a manual how to configure some aironet 1200 AP's with the use of a radius server?
The best would be a manual from start (reset to factory defaults) to a working solution.
The built-in radius server or a windows 2008r2 radius server are both possible for me.
I have tried both, buth did not succeed. (unknown EAP type and unknown username in the radius log)
Kind regards,
Ernst

i talk with a rep and i heard the new good news...there is no c sharp interface for berkeley db on handheld devices yet, it will be released later.
imagine one having problems executing a simple select statement due to the first release bugs...
dissapointing...
good article rekounas once again, your blog was very helpfull especially on my first steps in the olite universe, please keep it up

Aironet 1200 - error in web interface

Hi
I am attempting to configure 2 Cisco Aironet 1200 series devices for conection to an existing WLAN. Neither AP will be the Radius server.
I am able to connect to the device using IE and the IP address - however - as soon as I make any changes in any screen the screen then displays a message "Error on Page with a "!" in triangle.
This then prevents me from Applying the change asnd so configuring the device.
Anyone seen this before and know the solution - is there a bug in the web interface?

Is there an explanation along with it? Can you include a screenshot to your response? Screenshot will be helpful to diagnose the problem.

Cisco Aironet 1200 wireless network very slow

I have a simple wireless network set up, 2 - Cisco Aironet 1200 AIR-AP1220B-A-K9 wireless access points with 2 dBi Diversity Omni directional Ceiling Mount Antennas. They are the only devices connected to a Multitech Routfinder router, the WAN side the router is connected to a dedicated DSL connection. They are powered by AIR-PWRINJ3 power injectors. The WAP get the IP address from the DHCP in the router.
When connecting to the wireless network it runs very very slow, the signal strength is excellent and the connection speed is 54 mbps. But when opening a web browser it takes for ever to load a simple page like msn.com. If I connect the notebook directly to the router it runs very fast. We have tested with several notebooks and have the same problem. When I view the available wireless networks in range the only two that show up are the two Cisco 1200 WAP.
I have done the following with no improvement:
Change the channels from auto to 6 on one and 11 on the other.
Reset to factory defaults.
Update the firmware to c1200-k9w7-tar.123-7.JA2.tar
Replace the 802.11b radios with 802.11g radios AIR-MP21G-A-K9.
Disable the Aironet extensions.

Thanks for the info.
The documentation say not to switch from auto to full duplex or half duplex when using inline power, well I think it says the AP may reboot. I may have tried half duplex before I upgraded the firmware.
While upgrading I disconnected the AP, used a patch cord to connect it to the router and pluged the power directly into it to make sure the wiring to the AP was not the problem and it did the same thing.
However, when trying to upgrade the firmware it took ~ 45 minuets to upload the image and filed a couple of times retrying. I connected the AP to the notebook directly with a crossover cable and it uploaded in about 45 seconds.
That got me to thinking that there may be a problem with the router so I have replaced it with a Linksys.
In the mean time the DSL went down yesterday so I have not been able to test the new setup.
The cables are T568B

Apple Airport Express to Aironet 1200 AP Configuration???

I currently moved from my Cisco Linksys wireless router to an Cisco Aironet 1200 AP. The reason fro doing this is that the linksys had limited configuration capabilities and the wireless router would need to be rebooted every three days or so. But that's a different issue.
The linksys Cisco router worked great with the Airport Express Ver. 7.4.2 the Linksys located all three Airport express's. i am using them to bridge for each of my stereo throughout the house. But as stated occasionally I the Cisco router would loose the ability to connect to the Airports.
I decided I would beef up my wireless because I run many wireless devices 3 printers 2 laptops and 3 Airports plus 2 Iphones. So as you can see pretty heavy on the wireless.
So the problem is that I installed the 1200 AIR-AP1231G-A-K9 code: c1200-k9w7-mx.123-8.JEB configured basic WPA / TKIP PSK. My laptop can connect my Iphone can connect. Both devices work well and no issues. THE PROBLEM is the Airport express devices cannot detect my AP unless I configure them to use the ethernet port then they work just great. But that's not helping I need to be wireless. I have spent hours going through but I have not found a solution. Does anyone else have this issue if so please let me know the fix.
Thanks,
rabalam

Any luck getting this figured out?
I'm having the same issue: Basically any wired computer can connect to airtunes, wirelessly on the airport, but I'm not able to go from wireless to wireless. I've tested this on a separate system, with successful results.
I'm guessing it's a setting in the WAP that I'm missing.

No coverage AP Aironet 1200

Hi,
I've configured 2 AP Aironet 1200, but anyone transmits a good coverage. If i move away 5 meters, the laptop doesn?t detect any wifi network.
I've proven to change different parameters, but the problem continues.
This device hasn?t antennas. Must I buy them? Or can it works correctly without them?
Thank you vey much

Hi Jose Luis,
As far as the Antennas go, there are some Cisco AP's that come with Integrated Antennas (AP1121 for example) but most do not (I don't think any of the 1200 Series does). Here is some additional reference material;
Cisco Aironet 2.4 GHz and 5 GHz Antennas and Accessories
http://www.cisco.com/en/US/products/hw/wireless/ps469/products_data_sheet09186a008022b11b.html
Cisco Aironet Antenna Reference Guide
http://www.cisco.com/en/US/products/hw/wireless/ps469/products_data_sheet09186a008008883b.html
Reference for 1200 Series**
2.4 GHz antennas are not included with the 802.11b or 802.11g radio modules in either version; they must be identified under a separate order line item and purchased separately. Note, the 802.11a radio module is designed with its antenna integrated to the radio module, and therefore no antenna selection is required or available.
From this good doc;

Best way to secure Aironet 1200 for small office

We are getting ready to install 4 aironet 1200 AP's into an office that will only be used by 5 people with T43 Thinkpads (Intel 2200 built-in card).
What is the best method to secure the connection and prevent the outside world from accessing our internal network?
I don't feel WEP/WPA encryption is enough -- Would be interested in using the built in security that comes with the Aironet and not an external security server, yet.
Any info or push in the right direction is greatly appreciated.
Thanks

You could pretty easily use the "local" RADIUS built-in to the AP firmware and implement LEAP or EAP-FAST.
Both are pretty easy to set up, the AP can handle that small load without any real performance issues, and the Intel client software supports it (you'll want to make sure all the client software and drivers are the most recent, there were some issues in the past).
Both LEAP and EAP-FASt will support seamless roaming, You'd set one of the APs up for WDS and the others to point to it.
Admin (add/change/delete users) via the Web GUI is also pretty straight forward.
Good Luck
Scott

TACACS Authorization of Web Interface on Aironet 1200 AP

I have the Aironet 1200 AP setup to authenticate and perform authorization for the CLI via TACACS. That is working fine.
However, the web interface is failing "ip http authentication". (Slight caveat - it works for a local user in the local AP DB - it does not work when it goes to CiscoSecure ACS to authenticate/authorize).
I can get to some pages (prompt and pass authentication), but certain pages (e.g. Services>>SNMP) where configuration steps are taken cause a second prompt is presented, username and password is provided, and it fails.
This is only evident from the output of a "debug ip http authentication"
What do I need to configure in ACS to make this work?
Relevant portion of config:
aaa authentication login default group tacacs+ local
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ local
no ip http server
ip http authentication aaa
ip http secure-server

I found the answer was to use a more specific "ip http authentication" statement. Specifically,it required the following:
CiscoSecure ACS:
Group Settings
Shell (exec)
Priv Level = 15
On the AP:
had to enable:

Firmware 12.3(8)JEB
Hello,
I want to control client associations when AP load is high.
Is there an MIB object that enables/disables client associations?
I have searched the supported MIBS, but i could not find anything.

An improper combination of power level and antenna gain can result in equivalent isotropic radiated power (EIRP) above the amount allowed per regulatory domain. Here is the URL which indicate indicates the maximum power levels allowed with the Cisco integrated antenna for each regulatory domain and also contain configuration setting.

How can I query signal strength FROM an Aironet 1200 AP?

We are trying to query the signal strength of each connected client on Aironet 1200 APs from the AP.
Does anyone know of a way to achieve this?
We have examined the MIB documentation for an SNMP solution and have not found the reqired OID/MIB. This solution would be preferable, but at this point we are open to ideas.
Thank you.

Thank you and a follow up ...

From the output it seems GAP_INDEX has some fragmentation problem. Can somebody suggest, what the output means particularly the "DEAD" one.
And also, how to do the fragmentation ??
Thanks for help.

Rajeev

I haven't taken the time to study the query in depth but I think 'dead' is an attempt to identify free exents that are too small to be used.
The original post leaves out some very important information such as the type of tablespace space allocation in use: dictionary vs local with auto-allocate or uniform extents.
As one poster noted if you use locally managed tablespaces wtih uniform extents then free space fragmentation by definition cannot exist.
With auto-allocate and dictionary mangement it can. Auto-allocate generally extents the time till a tablespace's free space becomes fragemented such that the space is not usuable and contains logic to reclaim via reuse but with the right combination of very small and very large objects the problem can still exist.
Dictionary management is almost bound to lead to free space fragmentation conditions for an active system though the adoption of a proper extent sizing policy can help: initial = next with pctincrease = 0 for all objects in a tablespace and the extent sizes for the larger objects being an even multiple of the small object extent size.
For auto-allocate and especially dictionary management when free space gets low the options are re-create the objects to consolidate all free space into a few large contiguous chunks or add another file. Sometimes you can relocate an object whose extents can then be reused by other objects. With uniform extents moving an object to another tablespace always creates fully reusable free space. Since objects should be where you want them the only real option then is to add free space is to add a file. Managing free space in a uniform extent environment then is genarally very straight forward.

Aironet 1200 LWAPP Conversion and WLC Authorization Issues

Please excuse the length of this.
I am trying to convert several Aironet 1200 series APs to the LWAPP Recovery image and register them with a WLC. There is no WCS involved.
All of the 1200s have b/g cards in them, specifically MP21G and MP31G, so per the "Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode" guide, I am good. The 1200s are older and obviously do not have the manufacturer certificate.
The WLC is running the latest code, AIR-WLC4400-K9-3-2-116-21.aes.
The APs are running 12.3(7)JA2 or 12.3(7)JA3, all of which per the upgrade document and the Upgrade Tool utility meet the minimum requirements being 12.(7)JA or greater.
I will first dive into the disaster of the conversion process.
First, I upgraded a 1200 with a MP21G radio module. As far as the Upgrade Tool, I specified everything mandatory (AP credential file, recovery image, time source) while leaving the WLC and DNS server information absent. It successfully loaded the image and created all the necessary keys. Soon after I upgraded the image, the AP started rebooting continuously. I downgraded the AP to IOS, and found that the AP no longer has visibility of its radio module. It is simply gone. I upgraded and downgraded the code on the AP, hoping in the process that it would rediscover the radio module but it never did. I have not taken it apart yet to see if there is anything physically wrong and I will, but it was working fine previously, so even though it is possible that the radio module has checked out, my mind just cant go there. Scratch one.
So, AP number two has the same hardware. After attempting to convert it seven times with complete failure, on the eighth it successfully converted. I changed nothing is the upgrade process. Cool. So, with this success, I wanted to add it to WLC.
Network overview: the AP and WLC (Management and AP-Manager) are in the same broadcast domain.
Ok, the WLC configuration. The WLC is in Layer 3 mode which per the documentation is the only supported configuration that the converted Aironet APs will support. The Management and AP-Manager interfaces have been defined and are up and pingable by the converted AP. The AP information (AP MAC address, SSC, SHA key hash) has been entered in the WLC AP Authorization list as well. SSC certificates have been allowed.
As far as DHCP options 43 and 60, none have been defined. Per the documentation, even if the WLC Controller is in Layer 3 mode, as long as the AP is in the same broadcast domain, the AP should do a LWAPP discovery and make a join request to the controller. Again, the AP can ping both the Managment and AP-Manager interfaces.
So far, the AP has not been able to join the WLC. There is nothing in the logs. I have failed to do a debug on the WLC to see what is going on, but one thing I have seen is on the AP debug, a AP-Manager not enough interfaces message.
All the documentation I have been referring to is the "Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode" guide.
I will put the AP on a different segment tomorrow and try the DHCP route.
It is probably something simple.
Any ideas? :)

Jason
From your post I belive you've done everything the right way...excetp: Have you activated Master Controller Mode? If you haven't, no AP is ever gonna be able to register with a controller. You need to activate it temporarily when you want to add new (converted only?) radios. Once the AP is visible on the master controller (in the Wireless tab), define the primary / secondary / tertiary controller for it. If you're finished with registering any new radios, disable it again.
You can find it under Controller -> Master Controller Mode
And yes...always keep the AP you want to convert in the same subnet as the management int (so you don't have to use DHCP and fumble around with the option 43 setting to find the controller). To help the Upgrade Tool work troublefree: Enable Telnet mode on the controller. Also, don't forget to enter the mgmt IP / user name / password in the Upgrade Tool. At least with this I was able to complete my upgrading and registering process successfully in my own environment.
Hope this helps...

Newbie help with Aironet 1200 access point

Hello everybody,
We "inherited" an Aironet 1200 access point with antenna's throughout our building. This was installed by a company that thought they would make money selling Wi-Fi access but now they have gone bankrupt.
We eliminated their router and installed one of our own, and we have it handing out IP addresses. When I plug it into the Aironet 1200 it works just fine. Users are able to connect wirelessly and access the internet.
I would like to change the SSID however so that it no longer reflects the now defunct companies name.
I cannot determine what IP address is assigned to the access point so I can't figure out how to access the management page.
I tried connecting to the ethernet port via a DB9 to RJ45 cable and hyper terminal. After connecting the cable and powering up the access point I am still unable to connect.
I realize once I get connected I will probably run into password issues, but I'd like to figure out how to get at least that far.
Any ideas?

since ur gonna change the ssid and there is a password...
1. reset the ap. before plugging power to ap, press hold the mode button for 3 sec or until the led becomes orange or amber, then release.
2. the ap is reset to default setting with ip address 10.0.0.1
3. either console or gui the ap and change the bvi to ur preferred ip address.
4. configure everything else as you want.

Cisco Aironet 1200 LAP Issues - LAP to Autonomous Mode

Greetings! After purchasing 4 of the Cisco Aironet 1200 G Series WAPs, I'm now running into a slight issue with them.
I received these last week with the understanding that if I didn't have the Cisco controller device, I could convert them from being the Lightweight Access Point, back to Autonomous mode with an IOS.
With this, I checked the documentation that came with the device and found the "Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode" or http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=Getting%20Started%20with%20Wireless&needs_authentication=yes&CommCmd=MB%3Fcmd%3Dadd_discussion%26mode%3Dshow%26needs_authentication%3Dyes%26location%3D.ee7c7c3.
From there, I followed the instructions listed under Converting a Lightweight Access Point Back to Autonomous Mode. Before the rename of the file, I checked the device and found AIR-LAP1242G-A-K9 for the Model No.
One of the Cisco Certified admins here was able to obtain the latest build for the IOS for the device or c1240-k9w7-tar.123-8.JEB1.tar. Per the instructions, I renamed the file to coincide with the model of the device.
I followed the instructions from there, and it looked as if everything was going well. However, after the upgrade, I'm running into an issue with the following:
File "flash:/c1200-k9w7-mx.123-8.JEB1/c1200-k9w7-mx.123-8.JEB1" uncompressed and installed, entry point: 0x3000
executing...
At this point, the device just locks up. All lights are lit green on the device. According do the documentation, it should reboot and from there, I should be able to access the web interface by IP.
I've tried to perform the upgrade again using the same IOS build, but the same thing happens with the lock up.
At this point, I'm assuming the issue is with the build of the IOS that I have and I may have to look at getting an older build. However, before doing so, I thought I would post something here to see if anyone had an idea.
I may have needed to refine my searching of the forums, but wasn't able to find anything in relation to my issue. If there is something out there, I do apologize for the post and will happily refer to any current information.
If you need any further information in relation to this, please let me know. Any assistance is greatly appreciated. Thank you!

Hi Jeffrey,
Reverting the Access Point Back to Autonomous Mode
Have a look at Step 3
http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp161272
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
Using a TFTP Server to Return to a Previous Release
Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
Step 3 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, and c1240-k9w7-tar.default for a 1240 series access point.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power from the access point.
Step 6 Press and hold MODE while you reconnect power to the access point.
Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
Step 8 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 9 After the access point reboots, reconfigure it using the GUI or the CLI.
