Can ClearPass send a disconnect request when the guest user expired?

Hi everyone:

      I have a question about the Guest user.

I regist a guest user throught the web page, and the expired time is about 1 hour. After 1 hour, the user can not login again. It will reject the authentication. I want to know, if the Clearpass can send a DM (disconnect request) message by radius packet to the NAS when the guest user become to expired status? If it's ok, how to do the configuration?

Re: Can ClearPass send a disconnect request when the guest user expired?

Yes, it will send de-auth radius packet. I have attached CPPM and Aruba wireless integration guide, which proivde basic guest regestration configuration.

Hello

    what's the meaning of de-auth radius packet.

Is that the packet in RFC3576 , Disconnect Message ?

 

2.1. Disconnect Messages (DM)

A Disconnect-Request packet is sent by the RADIUS server in order to
terminate a user session on a NAS and discard all associated session
context. The Disconnect-Request packet is sent to UDP port 3799, and
identifies the NAS as well as the user session to be terminated by
inclusion of the identification attributes described in Section 3.

Chiba, et al. Informational [Page 5]
RFC 3576 Dynamic Authorization Extensions to RADIUS July 2003

+----------+ Disconnect-Request +----------+
| | <-------------------- | |
| NAS | | RADIUS |
| | Disconnect-Response | Server |
| | ---------------------> | |
+----------+ +----------+

Hi,

 

Yes, its Radius Disconnect message.ClearPass should be configured as RFC 3576 server on the controller and Accounting should also be enabled on the controller. Need to enable insight in clearpass aswell.

Insight is not required for RADIUS Dynamic Authorization.

Hi,

 

"update your enforcement policy with Radius CoA disconnect when the the account expires."

 

how would you do that?

Re: Can ClearPass send a disconnect request when the guest user expired?

Use the Guest template (Configuration >> Start Here) to create a guest service.

This will generate the necessary enforcements and you are in need of the enforcement named "xxxxx Guest Do Expire", this enforcement will take care of sending radius disconnect message to the NAS when it is applied during guest user authentication.

 

Note: The above enforcement takes guest expiration action based on the do_expire value associated to the guest account.

You need to navigate to ClearPass Guest >> Configuration >> Guest Manager >> Expire Action and set it to either "Delete and logout at specified time" or "Disable and logout at specified time".

 

The above config is global, you can modify this value in individual forms using the filed name "do_expire".


Thank you,
