FDR Notes

• When using the flow detail records feature, you will need to reset the Packeteer unit if you ever change its management IP address. FDRs will not be sent until the unit is reset.
  
  
• If your collector is on the LAN and FDR packets are being sent on the INSIDE link, you will not see any measurement data on the NetFlowV5 or FlowRecords classes. Measurement data is recorded on these classes only if FDR packets are sent to the OUTSIDE link. In addition, when FDR packets are sent on the INSIDE link, policies and partitions cannot be activated on these classes.
  
  
• FDR records the DSCP value at the time the flow finishes. If you change a DSCP policy in the middle of a flow, the value assigned with this policy is the one recorded in the flow detail record. If you change a DSCP policy for UDP traffic during a time when there are no more packets for the flow (before the flow times out), FDR records the DSCP value that the packet entered the PacketShaper with; in other words, it does not record the value that was assigned to the flow with a DSCP policy.
  
  
• Changes made to FDR behavior impact the records emitted to all FDR collectors. For example, you cannot configure your unit to emit intermediate FDRs only to a NetFlow-5 collector, while sending end-of-flow FDRs to a Packeteer-2 collector, such as ReportCenter (which cannot process intermediate FDRs).
  
  
• The flow detail records feature works in conjunction with the following Packeteer features:
  
  
• Xpress — Flow records sent to an FDR collector through a compression tunnel will not be compressed.
  
• Direct Standby — To emit flow detail records from both direct standby units, both units must have FDR collectors defined and enabled. Because both units see the same traffic, the collector will receive duplicate FDR records. However, each FDR record contains a PacketShaper ID so that the collector will be able to distinguish which records came from which PacketShaper.
  
• Hot Standby — Both hot standby units should have FDR collectors defined and enabled. However, only the active PacketShaper unit will emit FDRs.
