H-REAP LWAPs losing VLAN mapping when fail to secondary WLC's

Hello,
I have three 5508 WLCs, running code 7.0.98.0 supporting 100+ LWAPs in H-REAP mode. The LWAPs are servicing 2-3 WLANs each. Some are using central authentication and local switching, some are configured for central authentication and central switching. When the LWAPs fail from one WLC to another WLC, the LWAP's lose all of their VLAN mappings and pick up the VLAN of the management interface on the new WLC.
All WLANs are configured to use the management interface on the WLC and the VLAN mappings are configured per LWAP on the H-REAP properties tab. The WLAN ID numbers and all the WLAN settings are the same across all 3 WLC's. I have created AP groups on all 3 WLC's and the AP group config matches across the 3 WLCs.
I can get the LWAPs to keep their VLAN mapping by creating an interface on the WLC with the VLAN ID of the locally switched/remote site VLAN and then setting the interface for the WLAN to the new interface. However, then the WLAN doesn't work, because the centrally located WLC doesn't have the remote site VLAN. It also seems to keep the VLAN mapping if I create the locally switched/remote site VLAN interface on the WLC , and point the WLAN to the management interface. This shouldn't be a necessary step though... In H-REAP with local switching, the LWAPs aren't using the interface on the WLC.
I found a note in the 7.0 WLC config guide that explains why the VLANs are picking up the management interface VLAN, but that same note says the VLAN mappings can be changed per LWAP/WLAN!
From config guide:
For hybrid-REAP access points, the interface mapping at the controller for WLANs that is configured for H-REAP Local Switching is inherited at the access point as the default VLAN tagging. This mapping can be easily changed per SSID, per hybrid-REAP access point
Anyone using H-REAP and been able to get the LWAPs to keep the VLAN mapping when failing from one WLC to another?
Thanks!

Shawn,
I went back and reviewed everything and everything was duplicated , Except... WLAN_ID. The Wlan ID tags were different. I created a test and failled my two test AP's and they both came up on the backup controller with the proper vlan ID. now I know. When it was working for everyone else I was begining to wonder if I found a new bug or it was my config. This is one I wont forget ..
Thank you

Vlan mapping lost when fail to secondary WLC

Hello
I have two WLCs,The primary WLC mode 5508 ,running code is 7.4.100.60, The secondary WLC mode 4402,running code is 7.0.230.0.
When ap working on 5508 wlc,it use flexconnect mode, when ap working on 4402, it will h-reap mode
ap mode:1242、1142.
question:
When ap fail to secondary WLC(4402),some ap will lost their vlan mapping information.not all of ap. during fail over, ap will doanloading firmware.
is there any way to solve? thanks!

I understand. Two controllers, two different code levels. 4400 is locked in at 7.0 code and you need 7.4 for the 2600 ap.
In your orginal post you state when aps fail over from one controller to the other you lose vlans and aps code upgrade/down grade. This is not a support deisgn. You cant properly failover betwen different code versions.
If you want them to stop failing over and clients dont roam from aps on controler to 1 to aps on controller 2, simple remove the controllers from the shared mobility group and put the controllers in their own group.

Vlan mapping missing from flexconnect AP

I am having
issue with flexconnect mode AP. They are losing vlan mapping very frequently. I need to reconfigure the vlan mapping then only client starts getting IP addresses. Please let me know what may be the issue.
AP model: AIR-CAP3602I-N-K9
WLC model: AIR-CT5508-K9
Regards,
Vijayanand

The configuration on the controller must be the same between the time the access point went into standalone mode and the time the access point came back to connected mode. Similarly, if the access point is falling back to a secondary or backup controller, the configuration between the primary and secondary or backup controller must be the same.
You need to configure the Flex connect AP—switch --- controller , for the example to go through proper steps.

Process flow hangs when mapping execution fails

Hi,
Has anyone faced the 'process flow hanging' problem after upgrading to OWB 9.2.0.4? Don't know why this is happening again after the upgrade. The audit browser clearly indicates one of the mappings has failed and workflow tables indicate there was a notification upon failure. The process flow runs several sub process flows each containing 5-6 mappings.
Also, the mapping that failed (due to unique key violations on the target table) executed the post mapping stored procedure although the post mapping run condition was set to 'ON SUCCESS'. Is this the expected behaviour for the post mapping operator when there are database related failures?
Our environment is OWB 9.2.0.4 on AIX 5.2.
Database version is 9.2.0.5. We recently upgraded the database from 9.2.0.4 to 9.2.0.5 and OWB from 9.2.0.2.8 to 9.2.0.4. Process flows are executed using sqlplus.
Thanks,
Chethan

Hi,
I would expect you to have less issues with 9204 as there were some fixes applied. So I have not seen this before.
To get into the mapping a little bit more, is this a row based mapping that is under the tresshold? In any case, if you specify "on success" I would expect it to only work on success... A database related error will also cause it to get an error, so this is interesting as well.
Does the error repeat at any case if there is a failure?

H-Reap vlan mapping groups

Hi
Im configuring a WLC 5508 ( version 7 ) with h-reap local switching.
All is working , yet i wonder if the vlan mapping can be done better.
Currently i need to go into each Lightweight Access point , enable h-reap, then set the native vlan , with the final step to map the vlan. This needs to be done for each AP. In an environment of 100's of APs i would take foreever. ( i thought one of the main points of the WLC is centralized management )
Am i missing something ? Is there an easier way to do this ?
Cheers, Pankaj

you should be able to set the VLAN mappings from WCS/NCS as well.
as well in 7.2 you can now do dynamic vlan assignment, though you still need to list the VLAN the HREAP can access

Problem switching from AP-specific to Group-specific VLAN mapping

Hello.
Some days ago, I updated our 5508 WLC to software version 7.5.102.0.
With that version, it should be possible to have a VLAN mapping specific for a Flexconnect group that is set within Flexconnect Group settings.
I did that for all my Flexconnect groups and it works fine with new access point.
For existing access point, which already have an AP-specific VLAN mapping, it is not possible to switch to Group-specific.
When I mark the WLAN in Flexconnect setting of the AP and select "Remove AP specific", I get the error message "Request failed: Vlan is not enabled on this flexconnect".
I wonder what the problem could be, because for newly installed access points, it works fine. Did I miss some settings?
Regards,
Sven Lindeke

Thanks for the fast reply.

Hi,
I've searched around to see if someone else has experienced the same issue regarding HREAP AP's losing their VLAN mappings; however I could not find any related topics.
Scenario
I've got a 5508 WLC running ver 7.0 with local VLANs assigned as follow:
VLAN 241 - Data Users
VLAN 253 - Voice Users
The HREAP AP's (Cisco 1242AG) running at the remote branches is mapped to the following:
VLAN 2 - Data Users
VLAN 253 - Voice
The Problem...
HREAP works perfect; users get the local DHCP addresses at the branch office and have no issues with connectivity. Once and a while some of the HREAP AP's will lose the VLAN mapping I've assigned to them. In this case I've mapped VLAN 2 to the SSID for the Data Users, I will get complaints that users can't connect to the network when I go check the HREAP AP's VLAN mapping it defaulted back to VLAN 241 (the same VLAN the local AP's at head office use for the same SSID). Of course with the Voice SSID I don't have this problem as it's using the same VLAN ID as head office.
Once I've corrected the mapping everything works perfect.
Why...
I just want to know why this happens, I've rebooted the AP's to see if they retain the mappings and they did. I've seen in the HREAP design deployment that it is preferred to use the same VLAN ID's of the head office where the WLC is located as for the same to the branch offices where the HREAP AP's are located.
I can see why as this will resolve my problem, however this network was designed without the knowledge of HREAP being deployed to the remote sites and I would like to minimize change from a LAN perspective.
Will this be my only solution by standardizing the branch office VLAN ID's the same as the head office network or should I be able to use different VLAN ID's for the branch offices?
Thanks for your time reading this and for your input. If you know any discussion regarding this, please add the url.

Hi,
I'm having the same problem. And I have two WLCs (WISM) with 7.0.220 version.
I think because of this BUG: http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtw92394&from=summary
Anyone knows how can I solve this problem?
I Have 42 HREAP APs, and when I have some link problem on the remote Branch and the AP lose for a few seconds Connectivity to the 1º Controller its loses the VLAN Mappings (all turned to the Native VLAN).

Adobe Premiere CC 2014.2: losing rendered files when using warp stabilizer

Hi,
I am constantly losing rendered files when using the warp stabilizer. So far I have tried about every hint I could find on the web such as cleaning the cache, rebuilding the rendered files, creating additional sequences etc etc.
Honestly I am getting tired of using a product that isnt cheap in the first place to rent and where a bug like this apparently persists over several product versions without being fully fixed (I have had this problem throughout 2014 but according to forum postings others seem to have problems with much earlier versions as well).
I would be really grateful if somebofy has any suggestion how this can be addressed.
I am also happy to help testing fixes - if there are any fixes available.
Thanks a lot and Happy New Year!
Martin

Hi Catherine,
Welcome to the Adobe forums.
Please try the steps mentioned below and check if it works for you.
1. Launch Premiere Pro and create a Project, go to File menu>Project Settings>Renderer and change the Renderer to Software only mode, delete previews if you get a prompt and then try to import the clip.
2. If step 1 fails or the Renderer is already on Software only mode, go to Start Menu and search for Device Manager, go into Display Adapters and Right click on the Graphics card to select Update driver software option, on the next screen choose "Browse my computer for driver software", then choose "Let me Pick from a list..." option and from the list select "Standard VGA Graphics adapters. You might need to change the screen resolution of your screen and once done restart the machine again.
Launch Premiere Pro and import the clip to check.

Unable to open xsl file in Jdev 10.1.3.4.0.4270 (XSL Map generation failed)

Hi Guys,
I am trying to edit an XSL file using Jdeveloper 10.1.3.4 and it gives me the error "XSL Map generation failed. Please use the source editor to correct the problems and return to the design editor".
In the Mapper Message Log i find these lines.
Line Number:(44) : Error: "xsl:import" XSL Element Currently not Supported
Line Number:(68) : Error: "xsl:apply-templates" XSL Element Currently not Supported
Line Number:(67) : Error: <xsl:template match="/"> and <xsl:template name="..."> are the only permitted <template> elements in the XSL
Any help / pointers is very much appreciated.
Regards,

Perhaps better late than never...
This is a limitation in JDeveloper that it cannot render an XSL in design/mapper view when it contains these features of XSL. Pretty much 100% of AIA transformations fall into this category.

Flex Connect Groups - WLAN to VLAN mapping

I have a question about configuring WLAN to VLAN mapping on FlexConnect Groups.
Do the mappings that are configured in the FC Group get inherited by the APs when they are placed in the group?
It seems like they do not.
I am playing around in a lab with a virtual WLC running 7.5 and an old 1131 AP.
If I configure the WLAN to VLAN mapping on the individual AP, it works as expected.
If I configure the WLAN to VLAN mapping within the FC group and add the AP to the group, it does not.
The AP does not inherit the settings from the Group.
I am wondering how you would deploy a lot of APs without having to configure each AP individually.
Thanks

Yes, you are correct. It is not like normal AP groups where it will map WLAN to AP belong to that AP group.
Anyway since you have to convert each AP manually to FlexConnect mode, you should do the WLAN mapping at that point as additional step.
FlexConnect Group is mainly to give fast roaming feature for FC APs in brach deployment solution (typically not so many APs). Also keep in mind you can have maximum 25 APs in FlexConnect AP group for WiSM2 or 5508 & you can go upto 100 in 7500 WLC. (see table 7.3 in below link)

Error : XSL map generation failed

I am trying to map two XSD and generate the XSL file which will transform from one xml to another.
Source XML
+<root>+
+<Hello>Well</Hello>+
+<World>Thats</World>+
+</root>+
Destination XML
+<root>+
+<property name="Consumer" value="Well"/>+
+<property name="Consumer" value="Thats"/>+
+</root>+
Since the the destination XSD has same element twice, in its XSD it appears only once. So there only one node in the XSL Map tree in the right side of the JDeveloper (version 11.1.1.5.0)
I can only drag lines from either <hello> or <world> from the 1st XSD to the <property> element of the second XSD.
When I changed the XML map's xsl source to match my requirement as follows
     +<xsl:template match="/">+
          +<root>+
          +<ns0:property>+
               +<xsl:attribute name="name">+
                    +<xsl:text disable-output-escaping="no">Consumer</xsl:text>+
               +</xsl:attribute>+
               +<xsl:attribute name="value">+
                    +<xsl:value-of select="/root/Hello"/>+
               +</xsl:attribute>+
          +</ns0:property>+
          +<ns0:property>+
               +<xsl:attribute name="name">+
                    +<xsl:text disable-output-escaping="no">Consumer</xsl:text>+
               +</xsl:attribute>+
               +<xsl:attribute name="value">+
                    +<xsl:value-of select="/root/World"/>+
               +</xsl:attribute>+
          +</ns0:property>+
          +</root>+
     +</xsl:template>+
+</xsl:stylesheet>+
It works when I test the xsl but I can not go back to the design mode, it is showing the following error
Error : XSL map generation failed
Error: This node is already mapped, repeating nodes not supported :
I am not able to map (drag lines) any more due this error. Please suggest how to create repeating nodes in the destination XSD
Edited by: neilghoshidc on May 21, 2012 6:53 PM

The XSL Map error is only in Design mode. Runtime shouldn't generate an error.
Also refer
Notes on the Mapper
http://docs.oracle.com/cd/B31017_01/integrate.1013/b28211/xslt_mpr.htm
When you map duplicate elements in the XSLT Mapper, the style sheet becomes invalid and you cannot work in the Design view. The Log Window shows the following error messages when you map an element with a duplicate name:
Error: This Node is Already Mapped :
+"/ns0:rulebase/for-each/ns0:if/ns0:atom/ns0:rel"+
Error: This Node is Already Mapped :
+"/ns0:rulebase/for-each/ns0:if/ns0:atom/choice_1/ns0:ind"+
Error: This Node is Already Mapped :
+"/ns0:rulebase/for-each/ns0:if/ns0:atom/choice_1/ns0:var"+
The workaround is to give each element a unique name.

snmp-server enable traps
do i miss anything else? any recommendation? Why i am getting that error message?
Thank you for your support and asistance.
Kind Regards,
mico

Hi Joe,
thank you so much for your kind reply. I configured the snmp RW community string on the switch matching the credentials on the LMS server but still getting the same error message when i try to assign ports no a different VLAN
here is my commands for the switch:
snmp-server community xxxxxx ro
snmp-server community yyyyyy rw
snmp-server host x.y.w.z version 2c yyyyyy

External drive error, does not mount: "Partition map check failed because no slices were found"

Hardware: MacBook late 2009 (2.26Ghz Core 2 Duo 2 GB RAM 250GB HDD) running 10.9.4, Hackintosh MacPro (3.29Ghz i3 16GB RAM 1TB HDD) running 10.9.4, external 3 TB Seagate Backup+ drive
As you can can see from the screenshot below,
The external drive was initially plugged in a Netgear WNDR4500 router by USB to be used as NAS. I was in the middle of updating the firmware when there was a power outage. Upon reboot, the drive no longer mounts, whatever it is plugged in (router, Mac, PC, etc.).
I ran DiskUtility on the partition map and volume, same errors. Here's an what I see:
As you can see above, the "Mount" icon is greyed out and I get the error message "Partition map check failed because no slices were found". If I select "the Archive" partition, the "Mount" icon is not greyed out but clicking it doesn't do anything. My HDD is basically unreadable.
I issued a few Terminal commands to see what was the problem, here are the results:
What can I do?
Currently running analysis on TestDisk and it is 50% after 48hrs. Need some help!

@ Allan Eckert: Unfortunately, reformatting is out of the question, I have 5 years of work on this!
@ Loner T: Yes, the firmware did successfully upgrade after router reboot and a bit of troubleshoot.
