Dot11Radio0 Interface in reset/down status

Hi,
I have the next problem.
The interface Dot11radio0 is always in reset / down status.
I can't link both AP.
They both are cisco AIR-AP1252AG-E-K9.
This have been working fine for 18 months, but this week suddenly went down.
I updated yesterday one of the APs to a new version, from the 12.4.10b-JDA3(GD) to the c1250-k9w7-tar.124-25d.JA1.tar but the problem was no fixed.
the other AP has 12.4.21a-JY(ED).
I've changes the role of the APs, the one with was root-bridge changed to non root-bridge and the one with was non root-bridge become root bridge.
Doing this, I changed the status of the interfaces, the AP with had interface dot11radio0 up up, become in reset down, and the AP that previously was in reset down, become in up up.
In the show log I see that the problem is:
Dot11Radio0, cannot associate: Authenticating
Interface Dot11Radio0, cannot associate: No Response
I leave the confs here.
Please, help me.

Dot11Radio0 stuck in reset status after changing the station role

Hi Everyone.
I've got a AIR-AP1231G-A-K9 router. IOS has been upgraded to the latest version c1200-k9w7-mx.123-8.JED. Everything worked fine before I change the station role from root to repeater or workgroup bridge. Following is my configuration:

Interface Dot11Radio0 stuck in reset. No matter I reload or powercycle the AP, I still get the same reset status on Dot11Radio0.
Please help! Any input will be appreciated.

In order to get either the repeater or the workgroup bridge functionality working, you would likely need to have a Cisco AP as root. This is because the repeater and workgroup-bridge functionalities require Cisco Aironet Information Element (IE), which requires a Cisco root AP. There is no standard for interoperability for these functionalities (not part of any 802.11 standards). You can always try to connect them, making sure that they are using the same authentication/encryption configuration. However, it is unlikely to work.

Interface dot11radio1 is reset down and does not works.

I configured ssid and is a nonroot equipement and whwn I do sh ip inter brief the status interface dot11radio1 is reset and down and does not assosciate with the root AP

Thanks very much!
Then untilk the noonroot is not associate the interface radio remanis in restet status protol down ¿is it?
My problem is that this Brigge working fine for a year ago but one day fails and I replace the bridge but the interface radio remain in status reset too¿can be that the extenal antenna is broken? and therfore no signal received by the interface and can not associate with root for it?
I try to put boths brigge close and test if interface radio is up and works fine .If works like this I think that is a problem with the extrenal anntena ( dipolo)

%LINK-3-UPDOWN: Interface Dot11Radio0, changed state to down

Hello,
On a 4402 wireless controller (7.0.220.0) with LAP1242AG-E-K9 and LAP1252AG-E-K9 access points I receive lots of messages like this:
Dec 9 12:55:16 ap-a1 1466: AP:001a.2f58.d4d6: *Dec 9 11:55:16.174: %LINK-3-UPDOWN: Interface Dot11Radio0, changed state to down

what is a little bit annoying, in particular for voice communications.
Is there a way to get more information from any logs or is there a similar problem discussion anywhere on this forum?
Thanks.

Hi Konstantin,
Unfortunately I do not think we have the radio status codes published, but I'll comment on them here:
Status 51: Reset on transmit completion. I'm not 100%, but I think this means the radio was supposed to reset (due to another reason) but had data to transmit, so it completed TX and then reset.
Status 52: Reset on completion of multicast packets. Similar to above, just with multicast traffic being queued up.
Status 37: Generic interface reset (up/down), often seen during bootup or on configuration changes.
Status 54: Radio interface was shutdown -- either configured by the user or perhaps part of the boot process.
Status 67: Reset after changing hostname on the AP. This also would occur on bootup once the config is loaded.
Status 71: Reset to update radio status on WLC. Also usually done upon AP joining the WLC after bootup.

Monitoring up/down status of Interfaces with IfType = voiceEncap (103)

EMC Ionix is annunciating lots of down interfaces in our network that reference interfaces with IfTypes = 103. voiceEncap.
What exactly does a down interface mean when the interface iftype == 103 ?
is it normal for these interfaces to be down?
What is the value for Ionix to continuing to monitor these interfaces ?
What is the risk if I don't monitor these interfaces ?

We see this a lot with DFM (which also contains some of EMC's code), and the recommendation is to unmanage these ports as they will typically be down when there are no active calls. When they are unmanaged, the alerts will go away, and no vital information is lost.

Cisco 1142AP Autonomous - Radio interface constantly reset and provides crash file

Hello All,
We have 10 Cisco 1142 Access Points currently configured as Autonomous and I'm experiecing very unusual behavior with the 2.4GHz radio interfaces on each of them. The IOS firmware is 15.2.2JB and they're connected to Cisco 2960 PoE switches. I'm not sure what could be causing this problem however it is service impacting and looks bad on me since I don't have a solution for it. One potential fix could be to upgrade the firmware to 15.2.4 but I'm sure if it is a firmware problem. Any advice would help. Here's an excerpt from the AP log:

Reset Processing Status function for Custom Document does not exist?

Expert,
I have a need to reset Process Status of Custom Document from
"Blocked - Awaiting Reply from Authorities" to previous status. Many times we will receive error messages from US AES and require further processing and resent.
According to help.sap.com documentation, i should be able to find this function through
System Administration. Choose System Monitoring ® Status of Customs Declarations/Shipments.
I don't seem to be able to find this in our GTS 7.20 system. I have SP 009.
Please help.
Thank you,

ok. I received the answer from SAP. The transaction to reset processing status of custom declaration is

Mobility Group Member Down Status

The mobility group members from our guest controller have went into a down status twice since upgrading the 5508 WLC to software version 7.4.110. What can we do to remedy the problem?

1. First upgrade the WLC to 7.4.121.0 version (this is pretty stable).
2. paste the config and logs from WLC.

Can i reset nidaq status codes, after +10846 code?

(sorry for my english) I use nidaq with hard real-time acquisistion in win2000, in double-buffered mode. Sometimes, my application, don't read the halfbuffer and 10846 code (is plus, is a warning) occur. After, every check of DAQ_DB_HalfReady return 10846 code, and i can't see if another failure in read occur. How can i reset the status code? Thanks, Piero.

Search the Knowledge Base for the document titled "What Is the Difference between Data Acquisition Errors -10845 and -10846?" It will explain what the error is and how to correct it.
The status code is updated and returned after each function call in NI-DAQ. There is no function call to go in and clear the error condition in the DAQ device (this is an eror in the software buffer anyway, not the hardware, so NI-DAQ may actually be generating it, not a status bit on the card). If subsequent functions generate an error (or message) then you can ignore it or write a wrapper for whatever error handling routines you are using to clear the value of the status variable. Error handling is something you should handle in software; but, most people use the error handler in th
e examples folders.

1242 AP stuck in oper down status

Hello,
I recently deployed a 1242a\b\g AP. I can see it in WCS (version 4.1). However, the radio's are stuck in a oper down status. At first I was getting an error that the power was insufficient. It is set up with an ethernet power injector. I switched out the power brick and injector. Now I just get the down status on WCS.
The radios show they are enabled and admin status is enabled, but so far every attempt to bring the radios up has failed. Is there something else I need to check or configure?

Hi Kendall,
Just to add a note to the good info you received from Frank. If the radios are down this sounds like you are still having a power issue. Have a look at this recent thread;
http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=WLAN%20Radio%20Standards&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddc4f01
Hope this helps!

PM order for set/reset user status

I have one requriement like this I need to update the user status for many operations of single PM order at a time when user sets or resets the status. Kindly let me know is there any function module or any bapi for this or can you suggest me how to proceed with the further actions to handle this.
thanks in advance for your help.

Hi Jaya,
Before i tell you the FM, there is something u must know about changing the user statuses in PM.
User statuses are sequential in nature. Eg, if current user status is 15 and you want to set the new status to 30, you must set it to 20, then 25 and then finally 30.
For this you must first fetch all the valid statuses for the PM order depending on its status profile.
Next, call the following FM repeatedly each time passing the next status number in sequence until you reach the desired status number:
'STATUS_CHANGE_EXTERN'.
Hope this is helpful.
Thanks,
Sonal
