We have configured FreeRadius 2.1.12 on RedHat ; Requirement ========== In a given WiMax-Packet-Flow-Descriptor VSA, we want to have following multiple WiMAX-Uplink-Classifier (attribute 9) as shown in the below packet capture: WiMAX-Uplink-Classifier: =================== 1. permit in ip src any dst any 0-66 priority 3 2. permit in ip src any dst any 69-65535 priority 3 1st Packet Capture (Expected Behavior) =============================== AVP: l=125 t=Vendor-Specific(26) v=WiMAX(24757) VSA: l=119 t=WiMAX-Packet-Flow-Descriptor(28) C=0x00: 8 TLV(s) inside TLV: l=4 t=WiMAX-Packet-Data-Flow-Id(1): 111 WiMAX-Packet-Data-Flow-Id: 111 TLV: l=4 t=WiMAX-Service-Data-Flow-Id(2): 101 WiMAX-Service-Data-Flow-Id: 101 TLV: l=3 t=WiMAX-Direction(4): Uplink(1) WiMAX-Direction: Uplink (1) TLV: l=3 t=WiMAX-Activation-Trigger(5): 4 WiMAX-Activation-Trigger: 4 TLV: l=3 t=WiMAX-Transport-Type(6): IPv4-CS(1) WiMAX-Transport-Type: IPv4-CS (1) TLV: l=3 t=WiMAX-Uplink-QOS-Id(7): 111 WiMAX-Uplink-QOS-Id: 111 TLV: l=46 t=WiMAX-Uplink-Classifier(9): permit in ip src any dst any 0-66 priority 3 WiMAX-Uplink-Classifier: permit in ip src any dst any 0-66 priority 3 TLV: l=50 t=WiMAX-Uplink-Classifier(9): permit in ip src any dst any 69-65535 priority 3 WiMAX-Uplink-Classifier: permit in ip src any dst any 69-65535 priority 3 Configuration in MySQL ================== Here are the inserts we have in the radreply table: //--- WiMAX Capabilities attributes INSERT INTO radreply (username, attribute, op, value) VALUES ('testuser', 'WiMAX-Accounting-Capabilities', ':=', '1'), ('testuser', 'WiMAX-Hotlining-Capabilities', ':=', '1'), ('testuser', 'WiMAX-Idle-Mode-Notification-Cap', ':=', '0'), ('testuser', 'WiMAX-ROHC-Support', ':=', '01');

Issue/Problem: ============ Version 2.1.2 and 2.20 -------------------------- In both FreeRadius versions 2.1.2 and 2.20 on RedHat, the 2nd Uplink-Classifier (permit in ip src any dst any 69-65535 priority 3) is showing up in a separate VSA on its own as shown below; Expecting to see it in the same VSA as show in the first packet capture. 2nd Packet Capture (Not an expected Behavior) ================================== AVP: l=125 t=Vendor-Specific(26) v=WiMAX(24757) VSA: l=119 t=WiMAX-Packet-Flow-Descriptor(28) C=0x00: 7 TLV(s) inside TLV: l=4 t=WiMAX-Packet-Data-Flow-Id(1): 111 WiMAX-Packet-Data-Flow-Id: 111 TLV: l=4 t=WiMAX-Service-Data-Flow-Id(2): 101 WiMAX-Service-Data-Flow-Id: 101 TLV: l=3 t=WiMAX-Direction(4): Uplink(1) WiMAX-Direction: Uplink (1) TLV: l=3 t=WiMAX-Activation-Trigger(5): 4 WiMAX-Activation-Trigger: 4 TLV: l=3 t=WiMAX-Transport-Type(6): IPv4-CS(1) WiMAX-Transport-Type: IPv4-CS (1) TLV: l=3 t=WiMAX-Uplink-QOS-Id(7): 111 WiMAX-Uplink-QOS-Id: 111 TLV: l=46 t=WiMAX-Uplink-Classifier(9): permit in ip src any dst any 0-66 priority 3 WiMAX-Uplink-Classifier: permit in ip src any dst any 0-66 priority 3 VSA: l=50 t=WiMAX-Packet-Flow-Descriptor(28) C=0x00: 1 TLV(s) inside TLV: l=50 t=WiMAX-Uplink-Classifier(9): permit in ip src any dst any 69-65535 priority 3 WiMAX-Uplink-Classifier: permit in ip src any dst any 69-65535 priority 3 Master Branch ------------------ If we configure the FreeRadius using the "Master" branch, we get the 2nd Uplink-Classifier in the same VSA as expected (as shown in the first packet capture) Wondering if the behavior in versions 2.1.2 and 2.20 is a bug and was fixed in the "master" branch or are we missing any configuration in 2.1.2/2.20 which is causing the undesired behavior? For our production implementation, don't want to go to the "master" branch if possible. Sorry for the last email, but want to provide as much details as possible. Thanks -Hanu
