  • 1.  AP AND Controller in Diff VLAN

    Posted Aug 31, 2012 07:02 AM

    Hi

     

    controller is in vlan 100 connected to HP core switch in IDF Side I've a old nortel switch were i couldn't create a native vlan 100 for AP, so i forced to connect AP in vlan 1, now the issue is AP is not provisioning its keep on reloading please find the below AP boot process. in VLAN 1 i've a DHCP server for users and AP is getting an IP address from that server, i've configured master ip address in AP eventhough its not provisioning. L3 is enabled on switch.

     

    Hope airheads will help!!!!!!!!!!!

    - Make sure no firewall between AP and controller

    - Make sure TFTP are allowed from vlan 1 to vlan 100

    - add "setenv serverip X.X.X.X' on AP (X.X.X.X = controller ip address)

    Remove the IP from VLAN1.  By default the switches uses the lowest numbered VLAN as the Controller's IP address.  In this case, you left VLAN1, which is the default VLAN at 172.16.0.254, so now when a client finds the controller it will be redirected to that IP.  Remove the ip address from VLAN 1 and it should work:

     

     

    config t

    interface vlan 1

    no ip address

     

    It will ask yo to reboot, but then it will use the next highest numbered VLAN interface as the controller's switch ip.

     

    Alternatively, you can always hardcode it to a particular vlan with the "controller-ip" command:

     

    config t

    controller-ip vlan X
