Hi, We are trying to bring up MACsec with Cisco and FR, and we are stuck because of Radius unable to send EAP-Key-Name AVP. Below is what is expected as per RFC4072 RFC4072 says "A home Diameter server receiving a Diameter-EAP-Request with a Key-Name AVP with non-empty data MUST silently discard the AVP. In addition, the home Diameter server SHOULD include this AVP in Diameter-EAP-Response only if an empty EAP-Key-Name AVP was present in Diameter-EAP-Request." But radius server is not sending EAP-Key-Name AVP (Radius Attribute Type 102) even invalid AVP present in the Diameter-EAP-Request". Below is the debug print of radius Sending Access-Accept of id 647 to 10.20.64.9 port 1645 MS-MPPE-Recv-Key = 0x84e5c624c3bcdeadca3c6210f24bd7b8336921ccc1c58399d397afc75770332c MS-MPPE-Send-Key = 0xa6c4860cc8092c251502f5adc3ee13586e05fe84cbbb8b6793b08d9523d12b1f EAP-Message = 0x03060004 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "user1" Does anyone have clue on this.
