Some guest clients stuck in DHCP_REQD state

Hi everyone,
We are regularly having issues with some (random) wireless guest users not being able to connect to our guest SSID while others are able to connect just fine. They get stuck in the DHCP_REQD state so do not even make it to the web authentication screen. We are running WLC 4404 code 7.0.98 and using the WLC (two of them) as internal DHCP servers with a /23 scope divided between the two of them. I have checked the lease allocations and there are plenty of ip addresses spare.
A couple of days ago, all the users connecting via APs associated via one of the WLCs were unable to get an ip address and were stuck in the DHCP_REQD state all day and we ended up rebooting the controller which seemed to fix the problem temporarily but today some users have again been unable to connect. The users connected to the second controller all apppeared to be working just fine. The config on both WLCs appears to be identical.
I have seen some previous discussion about this being a known Cisco bug and which have recommended a code upgrade to v7.0.116 and v7.0.220 and I just really wanted to know your thoughts about whether a code upgrade is really necessary or a misconfiguration is the more likely issue.
Just to complicate matters we are in the process of tunnelling all our guest users to anchor controllers in the DMZ but at present this issue seems to affect both users who are connecting to local WLCs and those that are being tunnelled to the DMZ controllers.
Fianlly, I just want to add that we are also looking into installing external DHCP servers in the DMZ to cater to the guest users instead of using the internal DHCP server on the WLCs. I just wanted to know of your own experiences ie whether a code upgrade will resolve the issue for now.

Thanks, Viten. We are looking at upgrading the WLC code to v7.0.220 asap. Meanwhile, the DHCP_REQD issue occurred again with all users connecting to one of our WLCs and I ended up disabling/re-enabling the guest SSID on that WLC a couple of times and that seemed to do the trick for now. Longer term, I think we may need to move to external DHCP servers in the DMZ.

Static IP clients stuck on dhcp_reqd after upgrade to LAP

I have wireless thermal printers that have static IP addresses. They are on an open wlan and the dhcp required box is not checked.
The client gets hung at DHCP_REQD even though the client has a static address.
Controllers are standalone wlc4402(x2) running 41.1.185.0. Access-points are a mix of 1510, 1231 and 1242. Clients running 802.1x PEAP and DHCP are ok (different SSID).
This is the log from the WCS troubleshooting window:

We got wireless network cameras (Axis 207W) that only connects when they are configured with DHCP, If they are configured with IP-addresses they get stuck at DHCP_REQ.
Our Laptops connects with both DHCP or IP configured, on the same WLAN as the cameras.
The cameras has no sleep mode.

your issue is the client is not doing DHCP. is the dhcp required checkbox enabled on the wlan advanced tab?

Content Switching Module (CSM): Sessions stuck in closing state

Hi guys,
I'm troubleshooting a CSM with 4.3(1).
We migrated a real server from windows to linux, since then lot's of sessions stuck in closing state until the idle timer expires.
I traced the traffic from the client to the csm and from the csm to the real server what I saw is the following behaviour at the end of a session:
windows real server: client sends FIN -> real server acks the FIN -> real server sends FIN -> client sends RST -> real server sends RST -> CSM deletes session from session table
The linux real server mostly behaves like the windows real server but sometimes behaves as follows:
client sends FIN -> real server sends FIN, but does not ack the FIN sequence number of the client -> real server sends RST -> client sends RST -> CSM does not delete session from session table, it stucks in closing state
Does anybody know how I can solve this problem of half-closed sessions other than decreasing the idle timeout?
Is it possible to configure CSM to close and delete sessions not only on FIN-ACK packets but also on RST packets?
Or to use a different fast idle timeout when sessions are half-closed?
Many thanks in advance,
Thorsten

Hi Fabrizio,
CSM_FAST_FIN_TIMEOUT is already set to 10 seconds.
What I found out while testing is that CSM_FAST_FIN_TIMEOUT works with configurations where idle timeout is configured > 0.
But when idle timeout is configured to 0 (what meas no idle timeout) the csm seems not to use CSM_FAST_FIN_TIMEOUT: Half closed sessions will stuck in closing state.
Any idea why cms behaves this way?
Regards,
Thorsten

Azure Cloud Service Stuck in "Stopping" state for a long time (12 hours)

Does anyone have suggestions what to do with the issue I have. I tried to stop my Cloud Service the service is now basically stuck in "Stopping" State and been there over 12 hours. In my Cloud service there is 16 Virtual Machines I am using in
testing.
I tried to start Cloud Service but it also failed with error "Could not start the virtual machine deployment.".
Is there something I could do or some way to get Microsoft Support (without paying extra)? I have "Visual Studio Premium with MSDN" so i have no other support but billing from Microsoft :(

Managed to find the solution. I stopped and deallocated all the Virtual Machines. After that the Cloud Service status changed to stopped state. After that it was possible to start the Cloud Service again.

SQL Azure Data Sync stuck in Processing State since 5 Sep 2014

Hi,
I've a sync group stuck in "processing" state since 5 Sep 2014, have tried to restart the client PC, restarted the sync service and also tried to regenerate the sync agent key, but still in vain. Would anyone please help me to figure it out what's
the problem? As I have many sync groups running without any problem for more than a year and encountered this problem recently (in this 3 months).

Hi Bowen,
I've checked the local agent has been offline at 2014/09/05 18:00:00 UTC+8, as the shop close every night and they will shut down the computer, but they've turned on the computer in next day morning, and they keep turning that off at night, turn
back on at next morning.
I've checked the agent was online during that "stuck" period when the computer was turned on, as I could click the "PING SYNC SERVICE" and it reported it could reach the sync server, and I could also view from the portal that the agent
was online, just the sync group stuck in the "processing" status.

As the client need the sync to be fixed ASAP, cannot wait for the answer / help, I've removed the sync agent, compare the data (what data need to download from Azure to client, what data need to upload from client to Azure) and recreate back the sync group.
Hi Micheal,
Is this the workaround in your scenario? Since the Azure SQL Data Sync failed, the Microsoft support engineer will help to solve the problem from backend based on your subscription ID and Sync Group ID. Sometime delay might be expected. Your patience is
greatly appreciated. Thank you for your understanding and support.

Is there any way to know how much time swing client is on open state?

Is there any way to know how much time swing client is on open state? My requirement is to show a message some time after the swing client open i.e., 4-5 hours.

You could also consider using javax.swing.Timer and java.awt.event.ActionListener (or javax.swing.Action) which takes care of running the actionPerformed code on the EDT.

My iPhone adobe reader for iOS6 is stuck in update state and will not complete updating any ideas?

My iPhone 4 adobe reader for iOS6 is stuck in update state and will not complete updating should I uninstall and reinstall the app?

The update process is handled entirely by iOS and unfortunately, there isn't anything the Reader can do during this process to prevent "stuck updates". Generally, we don't recommend uninstalling unless you have to because uninstalling will delete all of the PDF's in your documents!
Here are some steps that work for most users:
1.       Make sure wifi and/or cellular data are turned on
2.       Test to be sure your internet connection is working by opening safari and browsing to a website (like www.adobe.com).
3.       Single tap the app’s icon on the home screen and it will pause the download. Now go back to the iTunes Apps store, switch to the “Updates” screen and click “Update” to resume the download.
4.       If this doesn't work, go to Settings -> iTunes & App Stores and tap the Apple ID to sign-out. Restart the iPad, go back to Settings -> iTunes Apps Store and sign-in. Tap the waiting icon to update the app.
Please let me know if this helps!

Workflow stuck in starting state after applying SharePoint 2010 CU December 2012

I have custom visual studio workflow which are associated with Custom content type. workflow gets triggered automatically when a file is uploaded to SharePoint. Everything was working fine till when i apply the following CU
http://blogs.msdn.com/b/joerg_sinemus/archive/2012/12/27/sharepoint-2010-and-december-2012-cu.aspx
After applying this my workflow get stuck in "Starting" state.
No error were logged in 14 hive logs.
Thanks in Advance!

It took me a while but I came up with a work around. There is a PowerShell script below that can be used to trigger the workflow. Hopefully this will hold all of us over until the official fix arrives.
First remove the auto start on change or new from the affected workflow
Edit the script below to match your environment
Add the script to Windows task scheduler with the PowerShell.exe in the command line
This assumes PowerShell.exe is in the path
Then add the full path and script name in the add arguements text box
Script:
#The purpose of this script is to start the SPD workflow with the windows task scheduler for a trigger
#This should avoid the check in-out issue caused by the December 2012 SP CU patch
#This needs to be run on an account with membership in the farm administration group for SharePoint and Shell in SQL
#You can use a find and replace to replace the server and other names with your actual names
#There are no status messages being used since this will be a scheduled task in the Windows task scheduler
#Add SharePoint modules and create variable space
add-pssnapin microsoft.sharepoint.powershell
start-spassignment -global
#Open the web site, list and the workflow
$site=get-spsite %site url%"
$web=get-spweb %Web url%

Agent get stucked in Reserved State

HI CUCCE gurus,
Need assistance on this issue. In our remote office, our Sales Team has a linegroup setup, the Sales extensions are part of the linegroup and at the same time its their ACD line when they logged in to Cisco Agent Desktop.
The issue is, when they got a call from the linegroup their CAD state change to "Reserved" and it stuck from that state and nothing they can do to change the state but to logoff, close the apps and log back in.
I enabled debug on once of the Sales CAD (see attached output).
Any troubleshooting tips that you can advise or detailed steps to check from our system.
Our CAD is 7.X
Our CUCCE is 7.X
Our CUCM 7.X
Thank you.

Hi Jhun,
Agent stuck in reserved state it means, the ICM has reserved the agent, but the call is not getting delivered to the agent extension.
If you are using SIP trunk, you would probably need to check the CSS and Partitions over the trunk. Also, any recent changes made on the CSS of the SIP trunk you would need to reset the SIP trunk.
The CSS on the SIP trunk should contain the partition of the phone.
Also, you would need to check on the Agent targetting rule in the config manager of the ICM. The agent extensions should be added to the Agent targetting rule
Hope this helps!!!
Cheers,
Dass

I have a set of 3 USB disks connected to my Time capsule (TC) via a USB hub. I usually switch the TC at night. When I restart the next day it stucks in amber state. When I disconnect the USB hub where my discs connects and restart, the TC will start properly. Any hints?

LOL.. don't switch off the TC.. this is fairly typical behaviour..
Or try a different usb hub.. but you could well and truly run out of hubs before you fix the problem.
Are you running latest firmware for your TC?
What error message is coming up in the airport utility.. amber led is a fault indicator.. look up what the actual fault is and see if it is for instance overloading the usb. You are using a powered hub??
Get one bigger USB hard disk instead of 3 smaller ones.

ISE Posture to guest clients

Hi Guys,
i'd like to know if is it possible to make a posture to Guest Clients using the Web Agent after they had been login into the portal.
thanks

Of Course it is possible. For detailed information please review the following guide
Configuring Client Posture Policies
http://www.cisco.com/en/US/docs/security/ise/1.1.1/user_guide/ise_client_prov.html
You can also create posture-specific authorization policies for all wired, wireless, and guest deployments by
specifying the Session:PostureStatus attribute in the authorization policies. This attribute has three
values, unknown, compliant, and noncompliant, which you can use n the authorization policies

Ashok
