Cisco AP c3502-I-K9 does not join controller

Network environment: (well configured and working fine)

2 AIR-WLC2106-K9 - Software Version 7.0.235.0

2 AIR-WLC2112-K9 - Software Version 7.0.235.0

10 AIR-LAP1252AG-T-K9 - Software Version 7.0.235.0

10 AIR-LAP1131AG-A-K9 - Software Version 7.0.235.0

I am adding a Cisco AP c3502-I-K9 to network.

It does not join any of the controllers.

Led is cycling through green, red, and off - that means "discovery/join process in progress" - never ends.

As wireless network is doing fine, I had only added to dhcp server dhcpd-subnet.conf file the above configuration:

class "Cisco AP c3500" {

        match if option vendor-class-identifier = "Cisco AP c3500";

        option vendor-class-identifier "Cisco AP c3500";

        vendor-option-space CiscoAPs;

        option CiscoAPs.server-address Controller-1-IP, Controller-2-IP;

    }

AP is connected to Cisco 6509 port as shown:

interface GigabitEthernet2/25

description Ponto 22.321 - Sala 121-A

switchport

switchport access vlan cisco-aps

switchport mode access

end

I am concerned with capwap protocol. Does it ask for any special configuration ?

Thanks

Rosa

NO there is no special configuration for CAPWAP.  Your current AP are using CAPWAP to talk to the WLC, so that should be working fine.

what is the real config line of

option CiscoAPs.server-address Controller-1-IP, Controller-2-IP;

For the AP the option 43 should be in hex not ASCII.

The AP you showed is a -A, Brazil should be a -T for the regulatory domain.

You should go back to the vendor that provided you the AP and have them get you the correct model.

Yup.  Steve's right.  You have an invalid Regulatory Domain for the WAP and the WLC.
