Displaying Flow Information

To display information about all flow rules associated with port 0, run the following command.

flow dump 0 all

This provides a list of details for a maximum of 1000 flows. Primarily, flow rules with the highest priority in group 0 are displayed, and flow rules in group 1-32 are displayed in random order. See an example of the output as follows:

testpmd> flow dump 0 all
Flow 0x562b9da2eb50, type FLOW, port 0, caller_id 0
  FLM base (group 1, FT idx 2, ref cnt 1)
  FPGA module CAT.CFN (idx 2, nb 1, ref 0)
    CAT.KCS.FLM 1
    CAT.KCS.KM 0
    CAT.CTE 0x004d
  FPGA module FLM.RCP (idx 1, nb 1, ref 0)
  FPGA module QSL.RCP (idx 2, nb 1, ref 0)
    QSL.QST range 1-1
      QST idx 1, TX_PORT 1
 
Flow 0x562b9da2d9c0, type FLOW, port 0, caller_id 129
  FPGA module CAT.CFN (idx 1, nb 1, ref 0)
    CAT.KCS.FLM 1
    CAT.KCS.KM 0
    CAT.CTE 0x004c
  FPGA module QSL.RCP (idx 1, nb 1, ref 0)
 
Flow 0x562b9da2ec90, type FLM, port 0, caller_id 129
  FLM owner 0x562b9da2eb50 (group 1, FT idx 2, CAT.CFN 2)
  Key id 3, protocol 0, priority 0

Flow dump finished

For an individual flow, use the following format.

flow dump 0 rule 0

This command retrieves details about flow rule 0 on port 0. An example of the output:

testpmd> flow dump 0 rule 0
Flow 0x562b9da2eb50, type FLOW, port 0, caller_id 0
  FLM base (group 1, FT idx 2, ref cnt 1)
  FPGA module CAT.CFN (idx 2, nb 1, ref 0)
    CAT.KCS.FLM 1
    CAT.KCS.KM 0
    CAT.CTE 0x004d
  FPGA module FLM.RCP (idx 1, nb 1, ref 0)
  FPGA module QSL.RCP (idx 2, nb 1, ref 0)
    QSL.QST range 1-1
      QST idx 1, TX_PORT 1

You can also save the output in a file. For example:
