From ce4b6451787389c5b0ebfac413c350ef3a424b8b Mon Sep 17 00:00:00 2001 From: Ting Xu Date: Sun, 24 Apr 2022 06:14:25 +0000 Subject: packetforge: add packetforge for generic flow to extras Add a new tool packetforge to extras. This tool is to support generic flow. Packetforge is a library to translate naming or json profile format flow pattern to the required input of generic flow, i.e. spec and mask. Using python script flow_create.py, it can add and enable a new flow rule for an interface via flow VAPI, and can delete an existed flow rule as well. Command examples are shown below. Json profile examples can be found in ./parsegraph/samples. Naming format input: python flow_create.py --add -p "mac()/ipv4(src=1.1.1.1,dst=2.2.2.2)/udp()" -a "redirect-to-queue 3" -i 1 python flow_create.py --del -i 1 -I 0 Json profile format input: python flow_create.py -f "./flow_rule_examples/mac_ipv4.json" -i 1 With this command, flow rule can be added or deleted, and the flow entry can be listed with "show flow entry" command in VPP CLI. Packetforge is based on a parsegraph. The parsegraph can be built by users. A Spec can be found in ./parsegraph as guidance. More details about packetforge are in README file.
