Hi, I have more than 10 HiPerARCs with differents software version. I all HiPerARC where the version is: V4.1.59 - 6 or V4.1.59 - 1 the disconnected cause and the speed rx and tx attribute for the calls is sent to my radius differents like the HiPerARCs with higher software version and it doesn't understand it. This is the configuration example about accounting: TCAzuLTaSa-CI1>>shoW accoUNTING The Primary Server Status is: ENABLED Primary Server is: 200.42.89.34 Primary First Backup Server is: 0.0.0.0 Primary Second Backup Server is: 0.0.0.0 Primary Destination Port is: 1646 Primary First Backup Destination Port: 0 Primary Second Backup Destination Port: 0 Max Primary Retranmissions: 3 The Secondary Server Status is: ENABLED Secondary Server is: 200.42.89.35 Secondary First Backup Server is: 0.0.0.0 Secondary Second Backup Server is: 0.0.0.0 Secondary Destination Port is: 1646 Secondary First Backup Destination Port: 0 Secondary Second Backup Destination Port: 0 Max Secondary Retranmissions: 3 Source Port is: 1646 Retransmission Timeout: 60 seconds Accounting Start Time: CONNECTION Log Unauthenticated Calls: TRUE Vendor Specific Attribute: ENABLED Active Accounting Server (Primary): 200.42.89.34 Active Accounting Server (Secondary): 200.42.89.35 Attribute Style: STANDARD Prioritize First Server in a Server Group: DISABLED TCAzuLTaSa-CI1>>show radius RADIUS SETTINGS Fill Null Attributes : DISABLED Attribute Style: ASCEND Authentication Algorithm: ROUND_ROBIN Interim Accounting Interval Status: DISABLED Interim Accounting Interval: 240 seconds IEA Radius Source Port Authentication ENABLED IEA User Radius supplied username DISABLED Send Unauthenticated STOP record ENABLED Send Accounting records for default user: ENABLED Report Acct IP Addr only for Primary Link: DISABLED Send only STOP Acct for failed services: DISABLED I know that it surelly can be fix upgrading to a higher soft version but anyone knows if it could be and configuration problem? I didn't find information about what means each one of the fields under radius configuration, anyone have some about it o could tell me what the optimal configuration? Thanks zim
