Cisco Switch not accept CoA from FortiNAC

[Lyyiheang]

Dear team,

I noticed that Cisco Switch are not accept Radius CoA/Disconnect Message from FortiNAC-F 7.4. I'm not sure if we need to have any customer RADIUS Attribute to pass to the Cisco Switch. I would like to share debug of pcap and Switch here.

Anyone who has experience this issue, Please kindly share

Note: RFC5176 Mode: system defined and Switch is configured CoA Port 3799

Thank You

Mac auth is not going to continue being viable much longer, if it could be said to be even viable at all now. All mobile devices sold within the last few years have the ability to use virtual mac addresses at the flip of a switch and I expect desktop operating systems will begin offering this as a standard feature as well. It's possible to do on basically any OS currently but not built in https://mobdro.bio/ .

Hello  Lyyiheang,

checking the CoA NAK response it complains about the session identifier.

For this you can use either "User Name" or the "Calling-station-ID".

Additionally i see you are adding in the CoA message itself the Access list attributes. This is not correct. In the CoA message you need to add an action such as bouncing the port or re-authentication. Then you add the Access lists in the Radius response (Accept-Accept) once the host re-authenticates.

This article provides you with the example when FortiSwitch is acting as NAS:

For FortiSwitch we use the Fortinet proprietary arrtibute 

Fortinet-Host-Port-AVPair

action=reauth-port

In your case of Cisco you can try any the following:
