Lost VLAN Mapping on WLC 5508 (Flexconnect)

[jguandalini]

Hi guys, I have a WLC 5508 and some AIR-LAP1131AG-T-K9 all in flexconnect configuration.

The problem is that 1130 Access Points lost the VLAN Mapping configuration without reason, simple change the vlan mapping to 999 and I need to reconfigure that.

I search in some documents on cisco.com but I can't find anything about this issue.

Could you help me please?

Thanks guys.

Seems better with the later code versions, but again, I'm assuming that everything is configured right.  I know that with some of the older code versions, some FlexConnect AP's would loose their VLAN mappings and that when templates and scripts just make it easy.  All about making it simple and working for the end users:)

I've created reporting tool for problems with flexconnect mapping

I replied with the commands... you just have to cut and paste.

Perfect Scott, thank you so much.

Can I share the script here to help other guys (Or you share, to earn deserved stars for your big help)? I will change only the name/vlan of IPs, ok?

[Scott Fella]

Sure...

I will also post the excel sheet later so others can use it too. The excel you will just have to copy the columns in order to a text editor so you can paste all the commands in order. I typically put all the AP's in the list since its pretty quick to run.

Glad it worked.

Great, when you post it, i will check the correct answer to help other guys.

For me is working as well on my test.

Here is an excel file that can go up to 2000 AP's and also a txt file that shows an example.  You will need to cut and paste from the excel to notepad or a note editor and then you can select all and paste it into the CLI of the WLC.  The spreadsheet has only one input field for the Wlan ID and the VLAN ID, so if you have multiple WLAN to VLAN mappings, just make a change to that and paste it into the text file.

Hi Guys

  I have WLC 5508 with redundant setup. We have problem on AP vlan mapping. Randomly the VLAN mapping on all AP is changing to management Interface VLAN.

I am wondering how to fix this. We have made the same setup on both WLC.

Any idea how to fix this .

Everytime if the AP lose VLAN mapping we have to log into all AP and check the VLAN mapping.

we are running

7.0.116.0 code both WLC.

[Scott Fella]

Why not use the excel sheet I provided to the other OP? This way you don't have to see what AP's you need to change and just send the commands for all of them.

If you issue a show WLAN summary and a show AP Group summary, then all the WLC's in your network have the exact same output?

ssengotaiyan,

The main reason for you to loose the VLAN Mapping is the mis-match in configuration b/n the Pri and the Sec. WLC.

Please make sure you have the WLAN configuration exactly matching ( including the WLAN ID).

Please let me know if that helps.

Thanks

Victor

Hi Victor

We have the same problem. but we have only one WLC (a 8500) with a HA. So the AP's is not "jumping around)

any idea?
