Dear All,

I am trying to setup EAP-TLS authentication mechanism for my WiMAX testing and following are the details.

1.  TATA ELXSI - WIMAX MS

2.  TATA ELXSI - WIMAX BS

3.  ARICENT ASN-GW version 4.2

4.  Free Radius AAA server version 2.1.3

Certificates exchange is through. When AAA server responds with Access-Accept, ASN-GW throws error saying "Validation of the Attributes in the Received packet failed"

Wireshark logs @ ASN-GW

I could not attach wireshark pcap logs due to size constraint. I have took print screen of only ACCESS-ACCEPT message copied to MS word.

What are the mandatory fields in Access-Accept and their valid values?

Service-Type attribute value is 2. ASN-GW is adding this attribute. Is this valid for EAP-TLS?

I am guessing this should be 8. I don’t have control over ASN-GW parameters modification.

Please let me know what fields are invalid in above ACCESS-ACCEPT.

Thanks !

Rathod.
