Hi Everyone,

I have the following scenario:

Two L2 Switches using a 1GB Fiber in a factory. I'm thinking use two AP 1510 as a Backup link between these two L2 Switches.

Can I do that ? I didn't find any documentation about that...

I had problem in my lab cause the 1510 are not forwarding the BPDU packets (STP) and both ports in my switch are forwarding...

Thanks in Advanced

Hi Andrew,

Thanks a lot for you reply

I think is not possible to configure the 1500 series using CLI.

Can you send me how can i get the same configuration (bridge-group 1 spanning-disabled)using the Controller GUI ??

Thanks in Advanced,

Hi Andrew,

I think I found what's is happening but I can't find a solution yet.

I make a lab using 2 switches, one crossover cable and 2 AP 1510 and 1 controller 2106.

When the crossover is connect, everthing works.. but when i disconnect the crossover cable, the AP don't send a LWAPP Discover packet using Wireless. I think the AP keeps send the LWAPP Discover packet using LAN cause it doesn't know that the LAN are not more avaliable

I wanna know how can i force the AP sends the LWAPP Discover packet using both LAN and Wireless

Thanks a lot for yours replys...

My Best Regards,

Are your 1510 in RAP or MAP mode? In RAP, the AP will only use its LAN cable to get to a controller. In MAP, it will try to use both, preferring the cable if possible. It will use its radio, but just to go through a RAP and find the controller...

OTAP might be useful to provide the WLC address, but it won't solve the issue of finding this controller...

Hi Andrew and Jeromehenry

Thanks a lot for your help

Here the informations:

WLC 2100 4.0.206

We are using LWAPP Transport Mode Layer 3

I think OTAP not works in WLC 2100

The 1510 near the controller is using RAP mode and the other controller is using MAP

What we are trying to do today.

Implement a filter in Switches to deny LWAPP packets to force the association between

the APs use only the wireless, not the cable.

Thanks a lot again,

My Best Regards,

Andre Lomonaco
