I'm trying to set up a wireless network, and learn at the same time. I'm using a Cisco 5508 WLC and a AIR-CAP3702I-A-K9 lightweight AP. The problem I'm having is that the LAP won't joing with the WLC. I have no switched or routers in between, only the 5508 WLC, and the AP plugged into the Ciscp PoE adapter. I have in internal DHCP server set up on the WLC, with the scope beint 172.16.16.100 - 172.16.16.200. The management interface is assigned 172.16.16.10/24 and bound to distribution port. The LAP is getting assigned an address ( see output ) which is in the correct subnet, but it never joins the controler. In fact it seems to give up after a while and request a new address from DHCP, so it keeps starting the process over with a higher IP address.

The output from : #debug capwap client event is also below. The only thing useful I can see is that it's sending a Discovery Request, but then reports

Failed to send packet to destination FF01::18C

also

Could not discover any MWAR

I don't know what MWAR means. WLC > show sysinfo

  • What is the WLC software version?

  • Also, what is the software version of the AP itself?

  • It appears that DHCP sets the gateway to 172.16.16.1 but it doesn’t exist. Either create it or remove it from the scope.

  • As an addition to user56700's requests, what do you see on debugs on the controller when the AP is trying to join? You also might try enabling more debugs on the AP to get additional messaging why it can't use the controller it found.

1 Answer 1

Reset to default

The software version that you are running on your WLC is not compatible with the 3700 series access points. You need to upgrade your code to at least 7.6.100.0 which is what Cisco indicates is the first version of code to support that AP platform.

You can find the compatibility matrix from Cisco here.

  • Yeah, this seems to be the problem. I would have expected some sort of "incompatible WCL" notification in the AP debug or vice versa though. Thanks.
