[flow-tools] Matching RP & switch records

[Daniel MacKay]

I have a hybrid router/switch.  The RP is issuing records like the following:

129.173.23.136/0   140.194.2.20/0  0.0.0.0  17 137    137      192         2
129.173.33.35/0  24.200.233.119/0 0.0.0.0   6  1058   1214     48          1

Which contain all the data anyone could want to do statistics, 
hunting for bad guys and debugging problems, but only for the first 
packet or so of a flow.  The rest of the information about a flow 
(how many packets and bytes) comes from the switch side in V7 records 
like this:

0    192.75.95.243/0   198.166.1.9      0      0    0     2123    22
0    193.61.122.237/0  198.166.1.9      0      0    0     80      2
0    63.91.145.36/0    198.166.1.9      0      0    0     74      1

missing source IP, ports, and other tcp header info.

My question is: is there any way to match up a Cat flow record with 
the correct RP flow record so that I can get full statistics on a 
flow?  Do you do it using the timestamp or something?

Any tips appreciated.  Please reply directly to me; anyone asks for 
it I'll post the responses back to the list.
