Spec's grammar for action_function_declaration states one or more action_statements, but some of these p4 targets have empty action function decls. Can you clarify the expected grammar moving forward?

I am getting the following error when I want to build the module for basic routing:

Hello, I am getting the following error when installing dependencies. I wonder how I can fix it?

I struggle with implementing a kind of multicast behaviour.
Is it possible to send a packet to a fixed destination such as 10.10.10.10, to look up this address in a table and get a match, resulting in sending the packet to, say, 10.0.0.1 on egress port 1 and 10.0.1.1 on port 2?

In the p4 spec 1.0.2 in section 13 is stated to use the egress_spec and specify a multicast group.
But mapping this to the triple (packet, egress_port, egress_instance) should be done by the buffering mechanism, and i don't know how to do this?

Is there an easy way to do this or any more detailed description of doing this?

Hi all,
I am getting below errors while running l2_switch example

[root@localhost l2_switch]# make bm
Linking: bm
/usr/bin/ld: cannot find -ledit
collect2: error: ld returned 1 exit status
/home/prai/p4factory/targets/l2_switch/../../makefiles/bin.mk:29: recipe for target '/home/prai/p4factory/targets/l2_switch/build//bin/bm' failed

Thanks,
Pavan

Even after applying my changes here: #14, I get a linker error when trying to run make on a new target.

I think main.c (which seems to be checked in for all other targets) isn't created by tools/newtarget.py?

Hi everybody,

I am new to P4 and I am trying to find a topic related to P4 for my internship project. In this regard, I have some questions:

1. I know Opencl is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators. What is the benefit of using P4 over OpenCl in case of packet processing.
2. Do you have any idea about a topic related to P4 for my internship project?

Regards,

Hi! Recently I was tring Integration with Mininet.

I followed the step in README, cd the directory p4factory/targets/simple_router/ and make successfully. Then I started the Mininet by the command:

./run_demo.bash

OK, and when I opened another Terminal, cd the directory and tried the command below:

./run_add_demo_entries.bash

to install table entries, I got into trouble:

root@ubuntu:/home/wasdns/p4factory/targets/simple_router# ./run_add_demo_entries.bash 
ImportError: cannot import name TFrozenDict
ImportError: cannot import name TFrozenDict
ImportError: cannot import name TFrozenDict
ImportError: cannot import name TFrozenDict
ImportError: cannot import name TFrozenDict
ImportError: cannot import name TFrozenDict

I'm not familier with Python, but I think it may be something wrong with thrift.

My thrift version:

Thrift version 1.0.0-dev

However..I have no idea about how to deal with it. Should I install the packet named "TFrozenDict"? But I didn't find anything by asking Google.

Can you help me? Thank you. :)

I'm trying to run the test for INT Reference Application described on routing-fail-over-test

The mininet topology has the following nodes:

mininet> nodes
available nodes are:
h1 h2 h3 h4 leaf1 leaf2 spine1 spine2

I can open an Xterm terminal for h1 by typing

mininet> xterm h1

However, by typing

mininet> xterm leaf1

The mininet prompt returned without any error message, but I cannot see any Xterm popup window.

What might be the problem in this case?

I intended to modify the Test Network Topology into a linear one.

My idea is to break the line between Spine1 and Leaf2, and the line between Spine2 and Leaf1, and setup a new connection between Spine1 and Spine2.

part of the original code in p4factory/mininet/int_ref_topology.py:

link_cfgs = [
    LinkConfig( 'leaf1', 'h1', 0 ),
    LinkConfig( 'leaf1', 'h2', 1 ),
    LinkConfig( 'leaf1', 'spine1', 2, 0 ),
    LinkConfig( 'leaf1', 'spine2', 3, 0 ),

    LinkConfig( 'leaf2', 'h3', 0 ),
    LinkConfig( 'leaf2', 'h4', 1 ),
    LinkConfig( 'leaf2', 'spine1', 2, 1 ),
    LinkConfig( 'leaf2', 'spine2', 3, 1 ),
  ]

I modified it as follows:

link_cfgs = [
    LinkConfig( 'leaf1', 'h1', 0 ),
    LinkConfig( 'leaf1', 'h2', 1 ),
    LinkConfig( 'leaf1', 'spine1', 2, 0 ),
   # LinkConfig( 'leaf1', 'spine2', 3, 0 ),

    LinkConfig( 'leaf2', 'h3', 0 ),
    LinkConfig( 'leaf2', 'h4', 1 ),
   # LinkConfig( 'leaf2', 'spine1', 2, 1 ),
    LinkConfig( 'leaf2', 'spine2', 3, 1 ),

   # New connection
    LinkConfig( 'spine1', 'spine2', 1, 0),
  ]

The topology setup seemed fine, but when I tested pingall under mininet:

mininet> pingall
*** Ping: testing ping reachability
h2 -> X h1 X
h3 -> X X h4
h1 -> h2 X X
h4 -> X h3 X
*** Results: 66% dropped (4/12 received)
mininet> pingall
*** Ping: testing ping reachability
h2 -> X h1 X
h3 -> X X h4
h1 -> h2 X X
h4 -> X h3 X
*** Results: 66% dropped (4/12 received)

Spine1 and Spine2 seemed failed to connect, or failed to exchange routes with each other.

What did I miss?

When i run the "git submodule update --init --recursive " under p4factory directory, it gives error for three submodules as:

• submodules/bigcode
• submodules/p4ofagent/submodules/indigo
• submodules/p4ofagent

I followed the README file under p4lang/p4factory and built the p4dockerswitch image successfully.

But I cannot find any instruction how to play with it.

p4factory/targets/switch/bmv2/README.md shows we can build bmv2 switch through make bm. However submodule bmv2 uses autoconf tool, and error occurs as no makefile found.

After run ./autogen and ./configure in p4factory/submodules/bm, it works fine when make bm in p4factory/targets/switch/bmv2/.

The install script install_deps.sh fails on Ubuntu 14.04 when either Java or Haskell is installed.

The reason is that when compiling thrift 0.6.2, it will try to build bindings for all languages that are currently installed on the system. The problem is, haskell and java bindings fail to build.

Since I think most language bindings are not needed for P4, is it possible to deactivate all unneeded languages? By default, thrift tries to build them all:

./configure --help
  --with-qt4              build the Qt library [default=yes]
  --with-c_glib           build the C (GLib) library [default=yes]

  --with-go               build the Go library [default=yes]
  --with-d                build the D library [default=yes]

The newtarget.py script is very useful, however, it only generates code to build with the old bm, not the new bmv2.

I managed to get a working environment for a new target by copying bmv2/Makefile, bmv2/main.c, bmv2/run_bm.sh and adapting all references to the target name, but it would be nice if the newtarget.py script did all that automatically!

Spec states "dynamic_action_selection" keyword whereas dc_example and sai_p4 targets use "selector". Is this a keyword change expected in next version of spec?

I was trying to add a ternary match rule in PD-CLI , which requires a priority, and I worked out the syntax is add_entry TABLE_NAME MATCH_FIELDS... ACTION_NAME ACTION_PARAMETERS... PRIORITY. However actually trying to do this causes an unhandled exception in Python to be raised. Some digging reveals that add_entry in pd_thrift_client.py puts the action specification before the priority:

if action_spec_tuple != ():
    add_entry_parameters.append(self.get_action_spec(action_name, action_spec_tuple))

if priority != None:
    add_entry_parameters.append(priority)

whereas the function at the other end of the RPC is expecting the action specification after the priority. Swapping the order of the above two blocks seems to fix the problem.

Running the command ./run_add_demo_entries.bash gives me the following error:
ImportError: No module named p4_pd_rpc.simple_router
ImportError: No module named p4_pd_rpc.simple_router
ImportError: No module named p4_pd_rpc.simple_router
ImportError: No module named p4_pd_rpc.simple_router
ImportError: No module named p4_pd_rpc.simple_router
ImportError: No module named p4_pd_rpc.simple_router

Can someone please help me with this.

My operation OS is Ubuntu 14.04.
I followed by the README.md step by step, and wanna to build a docker image.
But when I ran
make docker-image
in p4factory/targets/switch directory, the program seem work well, but when it processed step 14, there are something wrong.
First, it shows that
fatal: Not a git repository: ../../.git/modules/submodules/bm
but when I go to that directory, I tried
git status
the git showes that bm is a git repo.
Then after checking ,it shows

could you give me some instructions? Thank you!

When I try to launch the target switch https://github.com/p4lang/p4factory/tree/master/targets/switch/bmv2 with my own JSON file (my_program.json instead by given switch_bmv2.json) I get the following error message:

lt-simple_switch: ../../include/bm/bm_sim/bytecontainer.h:95: bm::ByteContainer::ByteContainer(const string&): Assertion `(size - idx) > 0' failed.

The JSON file is generated by command: p4c-bmv2 my_program.p4 --json my_program.json

The switch is started by command: sudo ./switch_bmv2 --log-console -i 0@veth0 -i 1@veth2 -i 2@veth4 -i 3@veth6 -i 4@veth8 -i 5@veth10 -i 6@veth12 -i 7@veth14 -i 8@veth16 -i 64@veth250 --thrift-port 10001 --pcap my_program.json. This command produces the error message.

Is it not possible to feed this bmv2 switch with my own p4 program?

When I try to make https://github.com/p4lang/p4factory/tree/master/targets/simple_router
I get these errors? How do I fix them?

The travis CI build for p4factory is broken. This is because travis recently added --recursive to their git submodule update --init command, which means we do not have an opportunity to replace ssh access by https access in the floodlight submodules before cloning them. I don't see an easy solution for this.

I got a problem when trying to use multiple P4 switches in Mininet. It seems that the interface MAC Address and IP Address of P4 switch isn't the same as shown using ifconfig command. In the 1sw_demo.py example, the MAC Addr seem to be 00:aa:bb:00:00:00 and 00:aa:bb:00:00:01. I wander how could I find the correct MAC and IP Address if I want to set the host arp when using multiple P4 switches. Thank you!

I was trying to setup the environment instructed by reference implementation of the Inband Network Telemetry.

However, when I build a docker image for the switch:

make docker-image

After a few minutes' running, I got these errors:

I had installed the dependencies, and cloned p4lang/thrift, installed and checked.

Hi,

Hi,

I'm new to P4. I'm trying to install p4factory. however, when I try to run ''./autogen.sh " I encounter the following errors:
./autogen.sh: 1: ./autogen.sh: ./autogen.sh: not found
./autogen.sh: 2: cd: can't cd to submodules/bm/
./autogen.sh: 3: cd: can't cd to submodules/p4c-bm/pd_mk/
./autogen.sh: 4: cd: can't cd to submodules/p4ofagent

If fact, there is no autogen.sh file in submodules sub-directories.
I have already ran ./install_deps.sh and sudo p4factory/tools/veth_setup.sh commands.

Any idea?

I studied and followed the instruction on p4factory/tree/master/apps/int

The environment was setup successfully. And running the reference application was OK on the terminal, but seemed no interaction with the Web client.

When I try to restarting-the-reference-application by running:

cd p4factory/mininet
sudo ./int_cleanup.sh

I received such output:

docker: "stop" requires a minimum of 1 argument.
See 'docker stop --help'.

When the first installation,I follow the README.
cd p4factory/targets/basic_routing/ make bm sudo ./behavioral-model
It is successful.
But today,I want to do the same thing,use these code
sudo ./behavioral-mode
error

I have a table with an action profile to implement ecmp. The code complies, how ever i am unable to add any entries to the table. A error is thrown saying the table does not exists. How do you add entries to a table that has an action profile?

My testing OS is ubuntu-14.04.3-desktop-amd64.

I followed every steps to setup the environment, and repeat several times, but always stuck on building the docker image.

After I run:

make docker-image

it executed for a while, and stuck after these output:

I have already run "make bm-p4ofagent PLUGIN_OPENFLOW=1" command in p4factory/targets/switch to build the switch target with the Openflow Agent, but when I execute the openflow_l2.py there is the error message:

How could I fix it ? Thank you!

I used the instructions in the README.md file for the INT code at the URL below.

https://github.com/p4lang/p4factory/tree/master/apps/int

The code fails to build with a Thrift error. I am using the correct version of Linux kernel (4.2.0-42-generic) and Ubuntu 15.10.

My P4 factory install worked fine and tested OK. The Docker install tested OK as well.

However, I just can't get "sudo make docker-image" to work and it complains that Thrift.h is not installed but I have installed Thrift. The error is below.

"configure: error: Thrift headers not found. Install Thrift from http://thrift.apache.org/docs/install/"

It would also be good to add notes to the INT README.md file as to why Docker is needed. Is it to replace a VM for Mininet use? Also, many instructions need sudo privilege to execute but the README.md file does not include the sudo in the notes.

Is there a way to get the status of a port ( whether its up or down ) in p4?

What does this const value mean exactly and how to decide it?

I have followed the steps of the readme, running the example in both VM and docker container. However, veth_setup.sh was not working on docker container.

Hi, Thank you for looking my questions! Sorry to have troubled you, I hope you don't mind.

When I followed the part Towards a better behavioral model: bmv2:

cd targets/l2_switch/bmv2/
  make bm
  ./run_bm.sh       # to start the data plane 
  sudo ./drivers    # in a second terminal, to start the PD APIs (RPC server)

I tried ./run_bm.sh, it happened that:

/home/wasdns/p4factory/submodules/bm/targets/simple_switch/.libs/lt-simple_switch: error while loading shared libraries: libnanomsg.so.5.0.0: cannot open shared object file: No such file or directory

But I had installed the nanomsg. Did I install the dependencies the wrong way? If not, how can I solved this problem?
I installed the p4factory again, but it still happened.

Thank you very much !

When I first runned the scripts named run_demo.sh and run_add_demo_entries.bash, they could work without errors and h1 could ping h2 successfully. However, some days later, the script of the run_add_demo_entries.bash could not connet to the port of 22222. I found that the the script of the run_demo.bash could not enable correspoing port (22222) successfully!
How could I solve this problem？

Integration with Mininet

Integration with Mininet provides a way to instantiate a network of nodes each running a data plane described in P4.

We provide a Mininet integration for one of our existing targets: simple_router

To run it, do the following:

cd p4factory/targets/simple_router/
make bm
./run_demo.bash
To install some table entries, run the following (in a different terminal):

./run_add_demo_entries.bash
You can then type commands in the Mininet CLI:

mininet> h1 ping h2

I tried the "Integration with Mininet" example of P4. When I enter "./run_add_demo_entries.bash", I get a thrift exception

I get the following message

Do you know what I am doing wrong?

Is there a way to dump data/the whole packet into the logfile or elsewhere?

The pcap dumps that are generated by mininet seem to not include all the packets going in on the device.

If there is a better place to ask questions like this, please just tell me, thanks!

When i use the following steps am getting the below mentioned Error message....

To run a simple test, run this in a different terminal:
cd p4factory/targets/basic_routing/
sudo python run_tests.py --test-dir tests/ptf-tests/

Can anyone give a solution. Thank you in advance.
