+# P4 Testbed
+
+In this repository we're have scripts to setup a network testbed with
+2 nodes and a Tofino Wedge 100BF-32X 100GBE Baremetal Switch.
+
+## Prerequisites
+
+- Hardware
+  - Tofino Wedge 100BF-32X 100GBE Baremetal Switch
+  - 2x 2m 40G QSFP+ to 4x 10G SFP+ Breakout Cable
+  - 2x Server with each 4 usable SFP+ Ports
+- Software
+  - Barefoot SDE
+  - SSH config for nodes
+
+## Setup and Usage
+
+The setup looks as follows.
+Depending on the setup of the QSFP Breakout cable the port numbers or the $n$
+may differ for $31/n$ and $32/n$ and the order may be different.
+
+The ports shown in this setup are only the connections between the wedge and
+the nodes (data plane).
+A separate network connection is needed to SSH into the wedge/nodes (control plane).
+
+For this testbed we're setting up a simple switch which forwards all traffic
+according to rules in the ingress.
+Look at [l1switch.p4](../l1switch/l1switch.p4) for more information.

+### 00-wedge_on_reboot.sh
+
+> This script needs to be run on the Tofino Wedge.
+
+When the wedge has just restarted for the first time we'll need to run this script
+on the wedge to load the necessary kernel module.
+
+### 01-wedge_compile_code.sh
+
+> This script needs to be run on the Tofino Wedge.
+
+### 02-run_switch_program.sh
+
+> This script needs to be run on the Tofino Wedge.
+
+### 03-wedge_port_configure.sh
+
+> This script does not need to be run.
+
+This script is just a placeholder and needs not to be run.
+Instead look at the [./03-wedge_port_configure.command](./03-wedge_port_configure.command)
+script.
+
+### 03-wedge_port_configure.command
+
+> This script needs to be run with a special command on the Tofino Wedge.
+
+Enter the configuration shell of the current switch program and setup the ports:
+
+- 31/0
+- 31/1
+- 31/2
+- 31/3
+- 32/0
+- 32/1
+- 32/2
+- 32/3
+
+That script needs to be run like this:
+`bfshell -f ./03-wedge_port_configure.command`
+
+### 04-wedge_route_configure.py
+
+> This script needs to be run with a special command on the Tofino Wedge.
+
+This script needs to be run on the Tofino Wedge.
+
+Configure the ingress of the switch program. Maps the `D_P` ports to the
+respective IP.
+
+This script is run with `bfshell -b $(pwd)/04-wedge_route_configure.py`
+
+### 10-host_setup.sh
+
+> This script needs to be run on the respective nodes with the section
+> of the hosts commented in and the other sections commented out.
+
+This script executes multiple scripts which setup the hosts.
+In our setup we'll only have two hosts, but this can be extended to other
+hosts as well.
+Information needed to do so is:
+
+- The interface name which is connected to the switch
+- MAC address of the interface
+- Unused IP address
+- And take a look at the appendix under "Adding new node"
+
+### 19-cleanup.sh
+
+> This script needs to be run on a node
+
+Removes all namespaces.
+
+### 30/31/... Scripts
+
+> These are helper scripts
+
+These scripts are executed by [./10-host_setup.sh](./10-host_setup.sh).
+
+### Run traffic
+
+From here on out you can run traffic between the hosts.
+
+## Appendix
+
+### Node and Wedge Ports
+
+How the port setup etc. looks like on the nodes and ports after everything is
+set up.

+### Adding new node
+
+We want to add a new node: =ncs-node3= to our network.
+
+We'll connect the 4 sfp+ ports of our node via a qsfp+ breakout cable to the
+Tofino Wedge on port 30.
+
+Given that the 4 interfaces on =ncs-node3= have the names:
+
+- enp6s1 with 00:00:00:00:00:01 (MAC) and 10.0.3.1 (IP)
+- enp6s2 with 00:00:00:00:00:02 (MAC) and 10.0.3.2 (IP)
+- enp6s3 with 00:00:00:00:00:03 (MAC) and 10.0.3.3 (IP)
+- enp6s4 with 00:00:00:00:00:04 (MAC) and 10.0.3.4 (IP)
+
+Find and replace the actual MAC addresses of the actual interfaces by running
+`ip a s` on the node.
+
+#### Adjust ./03-wedge_port_configure.command
+
+Add:
+
+```command
+port-add 30/- 10G NONE
+an-set 30/- 2
+port-enb 30/-
+```
+
+- port-add: Add the port
+- an-set: Set auto negotiation
+- port-enb: Enable the port
+
+To the command script before the
+
+```command
+exit
+exit
+```
+
+When running this take note of the `D_P` column of the new ports. You'll need
+to enter them as `egress_port` in the next script.
+
+#### Adjust ./04-wedge_route_configure.py
+
+Add the following:
+
+Replace `???` by the actual port number for the respective interface.
+
+```py
+
+bfrt.l1switch.pipe.SwitchIngress.t_l1_forwarding.add_with_send(
+    egress_port=???, dst_addr="10.0.3.1"
+)
+bfrt.l1switch.pipe.SwitchIngress.t_l1_forwarding.add_with_send(
+    egress_port=???, dst_addr="10.0.3.2"
+)
+bfrt.l1switch.pipe.SwitchIngress.t_l1_forwarding.add_with_send(
+    egress_port=???, dst_addr="10.0.3.3"
+)
+bfrt.l1switch.pipe.SwitchIngress.t_l1_forwarding.add_with_send(
+    egress_port=???, dst_addr="10.0.3.4"
+)
+```
+
+- egress_port: Value at the `D_P` column at the output of the last script.
+
+#### Adjust ./10-host_setup.sh
+
+Add a section for you new node like this:
+
+```sh
+# node3
+sudo ./30-add_namespaces.sh tb_node3_if0
+sudo ./30-add_namespaces.sh tb_node3_if1
+sudo ./30-add_namespaces.sh tb_node3_if2
+sudo ./30-add_namespaces.sh tb_node3_if3
+
+sudo ./31-configure_interfaces.sh tb_node3_if0 enp6s1 10.0.4.1/16
+sudo ./31-configure_interfaces.sh tb_node3_if1 enp6s2 10.0.4.2/16
+sudo ./31-configure_interfaces.sh tb_node3_if2 enp6s3 10.0.4.3/16
+sudo ./31-configure_interfaces.sh tb_node3_if3 enp6s4 10.0.4.4/16
+
+sudo ./32-setup_arp.sh tb_node3_if0 enp6s1
+sudo ./32-setup_arp.sh tb_node3_if1 enp6s2
+sudo ./32-setup_arp.sh tb_node3_if2 enp6s3
+sudo ./32-setup_arp.sh tb_node3_if3 enp6s4
+```
+
+Adjust [./32-setup_arp.sh](./32-setup_arp.sh) before running this script.
+
+#### Adjust ./32-setup_arp.sh
+
+Add the following section for your new interfaces like this:
+Replace the placeholder mac address with the actual MAC addresses of the interfaces.
+
+```sh
+ip netns exec "$NS" arp -i "$IF" -s 10.0.3.1 00:00:00:00:00:01
+ip netns exec "$NS" arp -i "$IF" -s 10.0.3.2 00:00:00:00:00:02
+ip netns exec "$NS" arp -i "$IF" -s 10.0.3.3 00:00:00:00:00:03
+ip netns exec "$NS" arp -i "$IF" -s 10.0.3.4 00:00:00:00:00:04
+```
