I don't think my DHCP option 43 is working

I get this from the console of the 1130 AG when I reset the button on the AP. I tried giving the CISCO-LWAPP-CONTROLLER.nccvt.k12.de.us the ip address of the management server's AP point but no dice.

thanks

Gary

The other network could be a problem after you connect but I don't think it is your controller issue. Try the date and time fix first. Let me know how that works out. I think your option 43 is not working well. Use option 43 with the IP Address of the Controller. Also, make sure that all the ports on your switches are trunked for the approriate vlans. The answer with the 1131 resides in your controller or network but appears to be your Option 43. I would begin a TAC call on this if you have. They will have you run several LWAPP debugs. I am betting your dns entry or IP address of the controller is not correct. Look at your dns server and see what the name of the controller resolves to. If you are resolving to the AP Manager interface and not the management interface that would be the problem.

Could you speak more about what vlan the AP will be plugged into and if that vlan has an ip helper address to the dhcp server?

DNS makes all this stuff go away...I would seriously consider it.

In DNS I took the controller name and pointed it to the ip address of the controller but I get this loop of the AP downloading the image and then it gets disassociated etc.

Here is from the console of the AP as it gets the image and then keeps recycling and downloading the image all over again.

Time to call either TAC or Meru!

Who is TAc or Meru?

Gary

Run! Run as fast as you can. Meru is a WLAN vendor that sells a system that violates the wifi alliance and 802.11 standards. They deny it of course but several trade mags have busted them on this. See the article below.

http://www.networkcomputing.com/showitem.jhtml?docid=1207f3_intro

The long and short of it is they violate the duration value built into the standard to monopolize the spectrum around them thus rendering other local WLANs useless. This is a violation not only of the standards but could be interpreted as a violation of the FCC good neighbor rules.

I have another very pervasive wireless system in the building. I did not have a problem with the 1010 AP's just the 1130 AG's. Could the other one be jamming me? I have to tell you that this is a heavy duty school building and I have trouble getting through the walls but not this other system.

Any way to deal with this?

The time is correct now but it still loops. The APs find the WLC it appears to download and then just keeps looping. In option 43 is it the ap-mamangement address or the management address?

Gary

Management interface. The MI controlls all functions to and from the controller. The AP manager is used to proxy a lot of info to the APs via the controller.

I do have dns pointing to the management ip address not the ap-management address. I have all Cisco switches and I think they are vlan1 but when I changed to controller to vlan 1 it disappeared and I had to use a console cable to the wlc to get it back. It is running untagged at the moment. Actually I have to keep it on layer 2 in the daytime as I have 1 AP that will not show up under layer 3. Those APs are the older 1010s.

Gary

This is what I get from the AP-I note the "No more AP manager IP Addresses" hmmmm

When I do a debug on the WLC I get hundreds of these lines concerning the AP that keeps joining and then unjoining.

I don't know if I asked you this or not but did you look under the AP Manager interface and insure that it was tied to the same physical port as the management interface? There used to be a bug in the software that the first time you booted a WLC the ap manager reset itself to port 0. You had to manually reset it to port 1 or port 2, apply it, and then save the configuration. This would allow the APs to download code.
