Client PC IP Address in the RADIUS Accounting Log

[Jagdeep Gambhir]

I cannot obtain the client PC IP Address in the RADIUS Accounting Log after successfully login via PEAP with machine authentication method. I had checked and sure about the entire setup was configure correctly as all login attempt was successful without failure. I am able to grap all the information I need like Hostname, MAC Address, Login Time and Date, Group Name except IP Address. Any solution for this?

The setup scenario consist of:

1 x Cisco Catalyst 4500 Switch running CATOS version cat4000-k8.8-4-5-GLX.

1 x Win2000 Domain Controller running Active Directory and DNS Server.

1 x Win2000 running DHCP serving 2 network scope.

1 x Win2000 running Entreprise CA and Cisco ACS 3.2 with External Windows DB configured.

All the servers join to the domain as member server.

All the servers loaded with servicepack 4 and latest patch updates.

1 x WinXP Pro loaded with servicepack 2 acting as Client PC with PEAP and Machine Authentication selected.

Thanks

No solution for the Sup in question. You need DHCP-Snooping to achieve this. Let me know if you'd like to walk through how to achieve this on an IOS-based platform for the 4k.

Hope this helps.
