Urgent help? for Standalone AP users are not getting ip addresses

Dear friends,
i have Cisco LAP1140 series access points and i wanted to use them as autonomous , so i converted their ios from light weight to autonomous to
c1140-k9w7-tar.124-25d.JA image.
my network senario is
CORE SW + Access SW + Access points
Core SW:
act as a dhcp server for wireless user
for WLAN vlan 16 is configured on it
configured dhcp pool here for vlan 16
Access SW:
access points are cooneted with it
and every switch port assign to vlan 16 that is connected to AP
Standalone Access Points:
connected to access switch and have assigned static management IPs from vlan 16 that i have excluded in DHCP Pool in core switch.
configure only one ssid and broadcast
both radio 5ghz and 4.2 ghz are up
i can ping the gateway from each Access point to core switch
but the users can not get the ip address from the ssid that is configured on APs.
below is the attached of configuration of the access point
please review the configuration and advise me where i have mistaken and what i have missing in the configuration?
please reply me ASAP because this is very urdent for me and your reply is very important for me
Thanks

Thanks for your reply Ven
actually i did not check that and it does make sence too may be problem with DHCP Scope
but you know why i did not check because there is an other scope on the core switch for Data users only the difference
of vlan numbers and names
but that data vlan users are getting ip addresses and connect normally to internet.
did you view the configuration that i attached with my 1st post?
if no please view it and advise me if i have any missing there.
further i ll check for DHCP in the morning to connect my laptop dirct with switch port to is that getting ip address or no.
Thanks

LAN was down ie Users are not getting ip from DHCP server after enabling DHCP snooping

Hi All ,
Enclosed file has network connectivity diagram.
1. L3 vlan's ie 2,3,4,5 and 6 are configured on ACC-CR1 and ACC-CR2.
2.Trunk is configured between Core switches ( CR1 and CR2) and access switches .VTP mode is transparent on all switches.L2 vlans are configured on all access switches.
3.DHCP is server is located at different location and is reachable over MPLS.
Without enabling dhcp snooping , users connected to access switches (Sw1,sw2,sw3 and Sw4 ) are getting ip address from DHCP server without any problem and everything is working fine.
But users connected to Sw3 and Sw4 are getting ip address from rouge DHCP server which is not pingable from any one of the switch.
So we have configured DHCP snooping for all vlan's on CR1 , CR2 , SW3 and SW4 and "trusted uplink ports" which are connected to WAN routers from CR1 and CR2 and also "trusted uplink ports " of Sw3 and Sw4 which are connected to CR1 and CR2.
As soon we have enabled DHCP snooping and trusted respective uplink ports , users are not getting ip address from remote DHCP server and even users connected to Sw1 and SW2 are facing same issue.
Note : DHCP snooping is not configured on SW1 and SW2.
Why users are not getting ip address from remote DHCP server as soon as we enabled dhcp snooping on Core switches and two access switches ie sw3 and sw4 ? what could have caused DHCP packets to be dropped ? Any idea would be appreciated .

Hi,
as you say: " HSRP is configured between CR1 and CR2 and Vlans are active on CR1" does it mean there are L3 intrefaces configured in each VLAN on your CR switches and ip hepler-address pointing to the remote DHCP server is configured on each of them?
I know it's difficult in a productive environment but IMHO you need to find out where are the DHCP offers dropped.
Either by enabling DHCP debugging or by capturing packets via Wireshark, e.g.

Cisco Flex Connect and users can not get IP Address by WAN

Hello my name is Ivan
I have a wlc 5508 with license base to 50 aps, i use a deployment flex connect. I already registered all my access points, I use web authentication to authenticate users guest, and the service dhcp is in the central site.
My issue is the users in each remote site, can not get an ip address by dhcp from the central site, they can authenticate in the guest ssid, but any users can not get an ip.
The request is passing by the wan in this way
Central Site DHCP - Router WAN - Remote Site - Users with notebooks. I use flex connect central deployment (all the traffic consulting to the wlc) .
perhaps i should use local deploy? The wlc is in the central site.
Can you help me to resolving this issue please? , perhaps any advice?
Regards
Ivan.

Thanks Osita
If I configure Central Authentication and I configure central switching I need to create a dynamic interafce for each remote site and each dynamic interface associated with a different VLAN ID, because I can not associate a single interface dynamic to the same VLAN ID, but in my case the client remote in each remote site have the same network segment with the same VLAN ID with the same SSID for guests. My goal is to configure web authentication with the local DHCP server at each remote site, will this work?.Each remote site have its own server dhcp.
If I configure authentication central authentication with central switching with web authenticacion as I set in my scenario?
My issues are the interfaces dynamics, because I have the same network to the customer guest with the same ID VLan in each remote site

Guest users not getting IP address

I am setting up Cisco wireless along with ISE 1.3 for guest wireless. The client is going to use the self-registration portal for guest wireless users. I followed this Cisco doc to configure the self-registration portal:
http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/118742-configure-ise-00.html
I tested this in my home lab and everything works fine. However, at the client users are not getting IP addresses from the DHCP server. This is the same DHCP server that is used for corporate wireless and if you connect that SSID, you get an IP address. I have looked what I configured at home and the client and everything looks the same. In the back of my mind, I feel something is missing, but I can't figure out what it is.
Edit: Not sure if this makes a difference or not, but they are using a Nexus 5K for their core switch and it hosts the SVI for this network.
Let me know what information you need and I will post it.
TIA,
Dan

Hello,
Some verifications below :
Did you verify if DHCP Proxy is enabled in wlc's wlan interface ? Case DHCP proxy is disabled, did you verify if the ip helper address is enabled in Nexus SVI ?
DHCP Scope is enabled in the DHCP Server or is enabled in the WLC ?
Verify if Trunk in the switch is enabled correctly passing all VLANs to WLANs ?
Verify if ACL to redirect configured in the WLC is allowing DHCP Server and DHCP Client to client receive IP Address and ports 8443 to Cisco ISE and DNS to resolve some address and get access to ISE Portal ?
The scenario is Local Switching or Central Switching ?

In Sales Order Users are not allowed to change price for any material

Dear all,
Please give me the solution :
In Sales Order va02 Users are not allowed to change price for any material .

Hi Amit
If you want that in VA01 manual as well as other pricing condiion entry and cahnges to be allowed and only in va02 users should be restricted ,then you have following alternative.
Go to T.Code SHD0
Select Transaction VA02.
Create a new variant ,give suitable name.
select option change with processing.
So u can run a va02 transaction and for every screen u can create screen variant and control data entry whether required , dispaly or hide.
in this for LV69a pricing screen disable update button .
so system wont change anything updated or cahnged in pricing.
further you can create the variant transactions from this transaction variant and assign to different users as per control requirements.
I think this will help you

Hi Sateesh,
This message will appear if either the background jobs are not scheduled, or UWL cannot tell that the background jobs are scheduled. The message no longer appears once you ensure the background jobs are scheduled to run via the user id UWL_SERVICE and that user is mapped to my portal user ID UWL_SERVICE.

T/F: iPhone users are not required to pay $15/month extra for Good Technology

I have a personal Droid RAZR M. You may wonder why I am posting in the iPhone forum but you are about to find out.
I have access to corporate e-mail via Good Technology. When I got this service set up at the same time I acquired the phone, I was required to upgrade from a $30/month 2GB plan to a $45/month 2GB plan just to have this access ("needed for access to company servers"). That was a surprise but I got over it. However, since then, I have come to learn the following:
1. It appears that other than VZW, no other carriers are charging users extra for access to Good Technology.
2. Based on a colleague's information from a Good Technology support engineer and a office mate who is using a VZW iPhone, VZW iPhone users are *not* *required* to move to an Enterprise plan aren't paying an extra $15/month. If one searches the Internet, I am not the only one asking about this.
If you are using a Verizon Wireless iPhone and have Good Technology on your phone, would you let me know if were *required* to upgrade your data plan and pay extra just for using Good Technology?
Thanks,
Techvet

I need to check some information at work about this, since they have some guidance on how their employees can connect to their corporate email with android and iphone devices.

OK.
Please follow this step.
1. As you said you are in coexistence step , so for now all endpoint already point to Exchange 2010 right?
2. Check legacy owa redirect that you already configure
3. In Exchange 2010 , Make sure that you already configure "Autodiscoverinternaluri" by this command set-clientaccessserver -identity "servername" -autodiscoverinternaluri
https://autodiscover.domain.com/autodiscover/autodiscover.xml. and don't forget to create autodiscover record in DNS
4. in Exchange 2010 , Make sure that you already configure "EWS" path by this command set-webservicesvertualdirectory -identity "XXX\Default web site name" -internalurl
https://yourinternalurl/EWS/Exchange.asmx -externalurl https://yourexternalurl/EWS/Exchange.asmx
5. don't forget to replicate freebusy from Exchange 2003 to Excahnge 2010 via public folder.
You error look like client cannot get autodiscover process please check it again.

Requisition users are not belonging to any purchasing organization

hi friends,
im using oracle 11i. as per our organization policy, requisition users should be able to make Receipts (for expense items only, not any inventory items) i.e. they will do receiving transactions. they are already assigned with Receiving responsibility . but when anyone clicks on Receipt the Select Organization Window is not appearing which normally appears to inventory users. and as a result Requisition users are not being able to find any PO to make receiving transactions.
requisition users are not belonging to any purchasing organization. pls help me how to make Select Organization Window available to those users.
Thanks,
LISAN

Hi Lesan,
You need to revisit "Receiving responsibility", check what are the menu and function excluded from the Responsibility and what is the main menu attached to this responsibility (e.g : Purchasing Receiver GUI)...
the best practice will be in your Receiving Responsibility, *1) Attach Menu : Purchasing Receiver GUI 2) Remove all entries for menu exclusions.. Save it.. Assign this responsibility to yourself.. Now try to receive.. I am sure now system will prompt you for an organization :)*
Please test and confirm..

Few users are not showing up in Corporate directory

We have few users at a repote site who are not showing up in Corporate directory. they have UDP profile and they are logged in . i ahve compared the configration with other user of the same site who is showing up in corporate directory and config seems fine
the User is LDAP integrated in CUCM and not a local user
the corporate directory is activated as default parameter for entire cluster
Please help if we have any further things to be checked ?

There was a similar issue a couple weeks ago here
https://supportforums.cisco.com/discussion/12343101/how-refresh-corporate-directory-cucm-91
Did you check if the users are not listed if you are registered at the subscriber?
this was the solution in that mentioned post:
"worked with cisco we found that the issue only occurs when the phones are registered to the subscriber server...when the phone is registered to the publisher, the directory shows the current information. this indicates and issue with the database replication between the 2 servers.
the databases have been reset and are replication is resyncing...this will take a couple of hours..."

Hello Jay,
here we are facing this problem, this company users not able to access both the portals at at time
If you want to access HTC and Armed at the same time you gotta complete SSO Config or User mapping between these two Portals. You can refer to the below link for more details.

CRM_ICSS_CREATE_COMPONENT...The component gets created but the material and serial number are not getting updated...It is very very urgent..please help....

I am not sure what information you are passing in given FM.
But in my case I have used FM 'CRM_CREATE_IBASE_FROM_EQUI' to create Ibase and component. It creates IBase and Component along with other details like material number and serial number.
you may refer the below code for the same >
Call the standard handling for crm equi load.
call function 'CRM_CREATE_IBASE_FROM_EQUI'
    exporting
      is_header         = is_header

    changing
      et_error_segments = ct_error_segment
