Cisco Wireless :: Autonomous 1242 In Scanner Mode?
Mar 8, 2012
we had a problem with a customer wlan in our warehouse (cannel overlapping). The troubleshoot needed a long time. For the future if requipred in case of problems i want to configure one access point in the warehouse as a scanner (please find picture in the attachement). The Autonomous cisco 1242 is now configured as scanner but i can't see any logfiles? Where can i find these informations. This is the cisco description of the scanner mode:Scanner—Functions as a network monitoring device. In the Scanner mode, the access point does not accept associations from clients. It continuously scans and reports wireless traffic it detects from other wireless devices on the wireless LAN. All access points can be configured as a scanner.

I encounter a strange problem on several AP 1242 in version 12.4(25d)JA1 of a customer : He has 10 autonomous AP covering The APs loose LAN connectivity randomly and therefore the clients don't work anymore. The AP are connected on a 2960 and a 3560 wich are in turn connected on a 3750 wich route the trafic.After checking spanning-tree no loops are present. When I check the counters on the AP involved I see the "trhottles" and "ignored" counters incrementing on the fa0 link of the AP impacted wich mean I think it can't handle the incoming traffic. This incoming traffic seems not to be too big however. I can see drops on the switch interface connecting the AP.

I have some 1242s and I can't get a straight answer on whether they can do both autonomous and lightweight or just lightweight.
Model number: AIR-LAP1242AG-A-K9.
I'm assuming that the 'L' in the model numbers means it's just lightweight, but searching Cisco's site and the Internet in general it's just not clear.
I know it works as a lightweight AP, can I run it in autonomous mode?

I can't seem to get the SSID RadiusTest to work properly.
Windows PC's show "Windows was unable to find a certificate to log you into the network". Macs don't authenticate either. Radius server isn't seeing any requests at all. Radius server is working because we are authenticating other things to it.
On my test 1231, IOS is 12.3(8) JEB1.

I try to change the AP mode of my LWAPP 1242 from local to bridge mode. But when the AP reboots it never associates with the controller, i have to reset it manually.I have the same issue with a LWAPP 1142.I tried to modify the AP mode configuration through the controller CLI but it's the same behaviour, AP never associates.Is there any particular parameter or configuration to perform before changing AP mode?

For the establishment of a WiFi Hot Spot with 5 Cisco 1242AG and 5 antenna AIR-ANT1728, I want to know what the config is the most suitable.
- One antenna in root mode and the other 4 in repeater mode
- Or 5 antennas in root mode
Between each terminal distance is about 100 meters outside?

What kind of hardware are people using for mobile bridges? I have not had good luck with Cisco 1242's in bridge mode with mobile-client enabled. The only reason we're using the Cisco access point over standard industrial bridges is because we need to manually forward the mac addresses of the devices behind the bridge. These are being installed on robotic forklifts. They have a generic ethernet scrolling marquee installed that does not maintain any active connections and drops from the fowarding table in the bridge if not staticly configured. I'm looking for an alternative because the roaming is not nearly as smooth as it should be.

I have just installed 3 access points along with 6 repeater access points all running V12.4. They are all AIR-AP1242AG-E-K9 using the 2.4GHz radio.
Prior to installation I bench tested that the repeaters would associate with the access points and if one of the access points was turned off the repeaters would automatically roam to another access point. I did not have all 9 devices powered up at the same time, but did have 2 repeaters and 2 access points powered up to simulate association and roaming.
During installation as access points and repeaters were powered up everything behaved as expected (repeaters were associating to access points etc.) however during installation once everything was installed the 3 access points were all powered down for half an hour or so and once powered back on the repeaters did not automatically re-associate until they were re-booted.
I have now configured the repaters with parent MAC addresses to reflect the above current assocaition pattern but not yet powered off the access points to test if this forces re-association as this is now a live operational site!!
Is it normal to have to re-boot the repeaters if ALL 3 access points are powered down at the same time? i.e. If only one access point is powered down will the repeaters automaically roam to another access point o.k.?

I’m configuring a Cisco 1142n AP in autonomous mode. The networking part is successfully working, multiple VLANs, SSIDs etc. I would like to configure one of my wireless networks to work with WAP2-PSK and the other with WPA-PSK.I’m confused as to what encryption to set on each radio and the ciphers to use on the SSID for each vlan to enable the best possible security. I’m not using a RADIUS sever in my network .point me in the right direction with the right CLI commands?

i have a air-lap01131-ag-e-k9 that was originally in lightweight mode and configured with a controller, but i am in the process of wanting to convert to autonomous mode, i am having issues with connectivity to the AP from my laptop.
i have followed numerous guides on this forum, i have successfully
downloaded correct firmware
renamed the firmware to .default
placed this in root of tftp server folder
connected laptop via console to view output
connected laptop via Ethernet to Ethernet port of AP
changed static ip on laptop to 10.0.0.2 set subnet mask to 255.255.255.0, default gateway to 10.0.0.1
held reset button on AP when applying power and waiting for radio light to flash red
AP gets a IP address then of 10.0.0.1
But even though both laptop and AP are in the same subnet, i am unable to ping the AP from my laptop and it doesn't start the tftp process
I have disabled firewall etc, and tried with both crossover and straight through cable, it seems there is something missing at this last stage, i even tried on a second laptop but that would not ping either, am i missing something.

I am configuring a mobile van that is used for a mobile health clinic to drive to several locations and when pulling into an allocated parking spot the van will connect via wireless automatically. I am using autonomous 1252 AP's and am considering either briding or workgroup bridging.
The issue I am encountering is that the AP inside a van is a router that has to do DHCP across the wireless and because the ethernet interface between router and AP in the van never goes down the router does not know to re-DHCP. I remember from way back there was an IOS command to track a serial interface and drop the ethernet if the serial link goes down. Is there an equivalent command for AP's to drop the ethernet interface if the radio interfaces go down?

I have several AP's of 1131 AG used in autonomous mode. Recently one of them stops responding: i was not able to access web management or ping its NIC. I've tried with reseting device to default but no success, even more when i plug ethernet cable to AP port nothing happens even NIC led's are not blinking at all.
On CLI console i am seeing repeated constantly such entries:
*Mar 1 05:19:04.086: %LINK-3-UPDOWN: Interface BVI1, changed state to up
*Mar 1 05:19:05.086: %LINEPROTO-5-UPDOWN: Line protocol on Interface BVI1, changed state to up
[Code].....
( i have new firmware but how to upload it without this interface running ? )

I was trying to upgrade the IOS image of the AP and I did a wrong manip.
I downloaded the IOS image (ap801-rcvk9w8-tar.124-10b.JA3.tar) from my TFTP server to the flash of the AP. Everything went find so far. But than I did an archive archive download-sw /overwrite ap801-rcvk9w8-tar.124-10b.JA3.tar and my AP reboot in LWAPP mode.
I should have done: archive download-sw /overwrite tftp://10.0.0.1/ ap801-rcvk9w8-tar.124-10b.JA3.tar instead!
Now I don't how to go back to autonomous mode. archive commando is not available anymore in LWAPP mode.

I am trying to have a setup where the AP running in autonomous mode also act dhcp server for the wireless clients.The only thing is that the vlan is switched across to the wired network.
So basically i am having 2 vlans, one for mgmt and other for data (for wireless clients) and both vlans are trunked to the switch.

we have 1262 (AIR-LAP1262N-E-K9) and we dont have WLC..and i want to convert it to Autonomous mode..i did the below steps... with using this file (ap3g1-k9w7-tar.152-2.JB.tar) download it from Cisco site. 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 Set the timeout value on the TFTP server to 30 seconds. Step 4 On the PC where the TFTP server is located, perform these steps.

Is the process for converting 1260 APs to lightweight mode any different from converting 1140s or 1250s? I've converted several APs to LWAP mode but this is my first 1260. Four 1260s need to be converted.I have one in a remote location that seems to be comatose. Here are the steps I took to convert the AP. Did skip/miss a step?
1. uploaded code to the AP ap3g1-rcvk9w8-tar.152-2.JB.tar
2. configured the AP for DHCP. It successfully leased a DHCP address. Controller information is provided via DHCP Option 43.
3. saved the configuration
4. verified the code, successful
5. disabled wireless radios
6. installed the lightweight code using the command archive download-sw /safe flash:/ap3g1-rcvk9w8-tar.152-2.JB.tar.The installation was successful
7. rebooted the AP
After that nothing. The AP has not leased another IP address. The switchport is active. The APs MAC address is registering in the switches MAC address table. The AP is receiveing PoE from the switch. I noticed that this AP is only receiving 6.2W of power where the three are getting anywhere between 8.8W and 9.3W. I am unable to ping the old static IP of the AP too.

What 113X AP model will work in Autonomous and LightWeight Mode? I want to buy some 113X AP's for my lab and want to make sure I don't get stuck with the ones that only run in one mode. I am looking at buying this one AIR-AP1131AG-N-K9 802.11a/b/g. Will this model work in both modes?

I have an Aironet 1250 AIR-LAP1252AG-A-K9 I am having issues with, and I am hoping for some direction on how to resolve them. I understand this question has been posted many times many different ways, but i have no luck unfortunately. Here is where I am: I can terminal into the AP, which has been set to factory default, with the username and password and enable password of Cisco. Once I am in the enable mode, I get lost.
Usually there would be an option to go to config. t, and work from there, but this AP does not have that option, Actually if I do a ? at the enable prompt, the commands list only starts with the letter C; but none are config.
I also cannot get into the web interface of the AP. The AP gets a DHCP IP from my DHCP server, (192.1681.128/24) but I cannot get into the web interface using the IP it gets from DHCP. The page never comes up. To add to the confusion, I cannot turn off the CLI event logging, although I enter the command "no debug all". Maybe I am off on what to put in. Nonetheless, it drives me crazy with messages every two seconds as I am trying to type while attempting to figure things out.
Overall, from reading the forums and doing Google searches, I am going on the assumption that the AP is now in lightweight mode, as opposed to autonomous mode, which is where I want it to be. I have tried the method of updating the firmware to the autonomous firmware from Jan 2013 for the AP. I use the TFTP method as I have found here on the forums a few times; I hold the mode button down while applying power to the AP, let the system LED turn red and release the button so the TFTP process can go through, but nothing changes.
I have the AP powered from a gigabit POE switch. The computer I am using for the TFTP is on the same sub net as the AP. I have tried using 10.0.0.6/24 for the computer with the TFTP on it, made sure the view all file extensions option was checked, and renamed the firmware to the .default extension-still nothing updates.
I also noticed that once I hold the mode button down for 20-30 seconds then let it go, the CLI output says the AP it is on the 10.0.0.x sub net, but I cannot ping the computer with the TFTP program on it. If i try to, it get a "Command not supported" message. So I will go on the idea that this is most likely why I cannot do a TFTP update.
About 30 seconds after I release the mode button and the AP boots, it will say it has a 10.0.0.x IP address, then it starts going crazy with messages that it cannot find a DHCP server.

we have a couple of AP1262N-E-K9 access point with firmware version 12.4(25d)JA1 operating in autonmous mode.
I attempted to measure the signal quality between the APs by setting one device to repeater mode while all others are in root mode. Then, I execute the following command: dot11 Dot11Radio 0 antenna-alignment
1. The output of "show dot11 antenna-alignment" is incorrect, the % value represents the signal strength in dBm without the - (minus). E.g. "-25 dBm" is displayed as "Signal 25% 0 dBm".Now, I know that is only a display error but still this is not clean. Is this a known issue?
2. Why are the measured signal strength values not displayed on the SSH console during the antenna-alignment test? Is it obligatory to use the console to see these values? Or is it also a known bug which might be fixed in later firmware versions?

One of my customer has an Apple IPAD 2.The IPAD is getting registerd through Cisco WLC 7.2.The APs that are being used is AP 1252 & AP 1242. The AP are configured in flex mode. The issue that we are facing is all the laptops and IPADs other then Apple IPAD are working but the Apple IPAD are not working through AES WPA2.It gives him a dismiss message and at time it gets connected but take a long time to get connected. Incase when the IPAD gets connected the following happens.
While connecting to the SSID it will ask for the preshared keyAfetr entering the preshared key it takes time to acquire an IP addressAfter the IP address is assigned it gives a dismiss message. If we do not click on the dismiss message then it will take anothere 30 seconds or so and get connected.

I am in the process of configuring Network Access Protection and just found out you can apply user based ACLs in the Network Policy. Will this work with a Cisco AP1242 in Autonomous mode? I saw some configuration guides for configuring User ACLs using the wireless controllers but not just Radius.
I have added the Vendor Specific Attribute of "Cisco-AV-Pair with two values of
-priv-lvl=15
-ip:inacl#10=deny icmp any any
I would expect all traffic to be denied when the user logs in due to the explict deny at the end of an ACL but I am not seeing that so I was unsure if Per-User ACLs work on standalone AP1240s.
I could add another rule to allow other traffic but I just want to see if the ACL would apply on a per-user/per-session bassis on the AP1200.
