Requirements for VLAN select feature in 5508 WLC

Lovro Lazarin

Hello,

We implemented WLC 5508 software version 7.3, with 8 Aironet devices, most of them are AIR-LAP1131AG-E-K9, and two AIR-LAP1242AG-E-K9.

I could really have benefits of VLAN select feature, but I noticed that it's not working like it should. Two interfaces are in Interface group, but from 45 clients only few of them has IP address from one subnet, others have from second sub.

I see requirements for this to work is 32 MB of flash on LWAP devices..I only have 16 MB..

Is there a way to work this thing out? upgrade of flash on devices or something ?

Thank you in advance and kind regards..

Lovro

I guess I was assuming you were doing AAA override.  So if the AP's are in local mode, will not work in FlexConnect, and the interface group is defined in the WLAN or in the AP Group, it should work. 

So since the WLC knows of the clients, your best bet is to bounce the WLC before you do your testing so the algorithm starts over.  Then look at the clients ip address and also look at what AP's they are connected to and see if you see a pattern.  See if the clients on the 1131 are working and not the 1242 or vice vesa.  I doubt that your interface is marked dirty unless you are using small subnet's.  To check that, in the CLI you would issue:

show interface group detailed 

Thanks,

Scott
