flow-print - Display flows in formatted ASCII.

flow-print [-hlnpw] [-d debug_level] [-f format]

The flow-print utility will display flow data in ASCII using pre-defined formats selectable with -f.

Some of the less descriptive column headers are defined below

Header Description ------------------------------- Sif Source Interface ifIndex. DiF Destination Interface ifIndex. Pr Protocol. P Protocol. SrcP Source Port. DstP Destination Port. Pkts Packets. Octets Octets (Bytes). Active Time in ms the flow was active. B/Pk Bytes per Packet. Ts Type of Service. Fl Flags, for TCP the cumulative or of the TCP control bits. srcAS Source AS. dstAS Destination AS. Start Start time of the flow. End End time of the flow. router_sc V7 IP address of router producing shorcuts. peer_nexthop V6 IP address of peer next hop IP address. encap i/o Version 6 only. Encapsulation size in/out duration Time in ms the flow was active. input Input Interface ifIndex. output Output Interface ifIndex. flows Number of aggregated flows. mTos V8.x ToS of pkts that exceeded the contract. xpackets V8.x Packets that exceed the contract.

-d debug_level

Enable debugging.

-f format

Select format. The default is appropriate for the export type of the flow data. Available formats are:

    0 1 line, interfaces, hex ports
    1 2 line (includes timing and flags)
    2 2 line candidate TCP syn attack flows
    3 1 line, no interfaces, decimal ports
    4 1 line with AS number
    5 1 line, 132 column
    6 show ip accounting emulation
    7 1 line, 132 column +router_id
    8 1 line, 132 column +encapsulation
    9 1 line with tag values
   10 AS aggregation
   11 Protocol Port aggregation
   12 Source Prefix aggregation
   13 Destination Prefix aggregation
   14 Prefix aggregation
   15 Destination aggregation (Catalyst)
   16 Source Destination aggregation (Catalyst)
   17 Full Flow (Catalyst)
   18 ToS AS Aggregation
   19 ToS Proto Port aggregation
   20 ToS Source Prefix aggregation
   21 ToS Destination Prefix aggregation
   22 ToS Prefix Aggregation
   23 ToS Prefix Port aggregation
   24 Full (Catalyst)
