Onboard Fail to Redirect After Client IP Address Change.

My Onboarding (two SSID's) is working until the IP address of Onboarding client changes.    No IP address change for the ClearPass, I can still put in Onboard client browser for https://MyClearpass/guest.onboard.php and it will continue to Onboard, but client won’t redirect when open browser to say http://1.1.1.1

  • Cache and history of the browser has been clear.
  • Onboard whitelist is including ClearPass IP address
  • DNS is working
  • Onboarding licenses are available
  • Move the client back to previous IP address, it will work

Does it configure somewhere in the Onboard process for a network to allow to redirect?  Aruba OS 6.5, CPPM 6.6.8

Re: Onboard Fail to Redirect After Client IP Address Change.

Why would the device's IP address change?

Re: Onboard Fail to Redirect After Client IP Address Change.

Forgot to mention: IP address change to a new subnet because the network reconstruction. 

The redirect pause is 3 seconds

Not sure about CoA/Client bounce.  The process is client connect to "onboard", CPPM steers client to "onboard-login" role with captive portal

Re: Onboard Fail to Redirect After Client IP Address Change.

Just to be clear, you mentioned 2 SSID onboarding. The IP change you are reporting is that between the two SSIDs, or is it on the same SSID?

 

You should try to avoid switching VLAN within a SSID at all cost; your client will not detect that the VLAN has changed and keeps trying with the already assigned IP address that does not have connectivity in that new VLAN.

 

Different VLANs between different SSIDs should be fine in most cases.

Re: Onboard Fail to Redirect After Client IP Address Change.

While I am doing two SSID's onboarding, I use one subnet, so no IP address change.

Also another point to mention: the working subnet is layer 2 to ClearPass, the problem subnet is layer 3 to ClearPass.

Thanks,

Re: Onboard Fail to Redirect After Client IP Address Change.

After working with TAC ClearPass engineer and controller engineer, he found my problem is NOT ClearPass, but in the controller. 

For the redirection to work, the new subnet/Vlan interface MUST be configured with an IP address. 

Confirm by ping at the controller with source of the new vlan: 

WC03 #ping 8.8.8.8 source 100
