Facility port and p4

Hi,

I have a question regarding an experimental setup with a node, a facility port, and a P4 switch in between. My issue is that I am unable to create a connection between the facility port and the node.

To provide some context, I was able to replicate the “facility_port” example for FIU and can ping the FABRIC node from FIU, and vice versa.

I can also replicate “Layer 2 Network Topology with Edgecore Wedge100BF-32X P4 Tofino Switch on FABRIC,” where a P4 switch is connected to two nodes that can ping each other.

My goal in this experiment is to combine the two: instead of connecting two nodes to the P4 switch, I want to replace one of the nodes with a facility port. After creating the node and facility port, I set up SDX for the FIU facility port and defined the physical ports. Then I set up the P4 switch so it could transmit packets. However, I have not been able to ping the FIU server from the node or vice versa (slice ID: b6b88889-1024-451a-8d5c-727a465c3e7d). Below is how I set up the slice (please see the slice for more details):

facility_port_vlan=’4017′
facility_port_name = “AmLight-EXP-Layer2-FIU”
slice_name = “DDoS with p4”
node1_name = “DestNode”
p4_name = “P4”
network1_name = “net1”
network2_name = “net2”
model = “NIC_Basic”

# print(f”VM Site: {site1}”)
# print(f”P4 Site: {site2}”)
# print(f”Facility Port Site: {facility_port_site}”)

from ipaddress import ip_address, IPv4Address, IPv6Address, IPv4Network, IPv6Network

# Create Slice
slice = fablib.new_slice(name=slice_name)

# Create Node 1 and its links
node1 = slice.add_node(name=node1_name, site=site1)
iface1 = node1.add_component(model=model, name=”nic1″).get_interfaces()[0]
# iface1.set_mode(“config”)

# Optional: Uncomment if Node1 needs an IP address
# iface1.set_ip_addr(IPv4Address(“192.168.0.2”))

# Create P4 switch and its links
p4 = slice.add_switch(name=p4_name, site=site2)
iface2 = p4.get_interfaces()[0] # Connects to net1
iface3 = p4.get_interfaces()[1] # Connects to net2

# Set VLAN tag on P4 switch’s interface (iface3) to match facility port
iface3.set_vlan(facility_port_vlan) # Sets VLAN to ‘4018’ (string)

# Add Facility Port
facility_port = slice.add_facility_port(name=facility_port_name, site=facility_port_site, vlan=facility_port_vlan)
facility_port_interface = facility_port.get_interfaces()[0]

# Create Networks
net1 = slice.add_l2network(name=network1_name, subnet=IPv4Network(“192.168.1.0/24”))
net1.add_interface(iface1)
net1.add_interface(iface2)
net2 = slice.add_l2network(name=network2_name, subnet=IPv4Network(“192.168.1.0/24″)) # Layer 2 network for facility port
net2.add_interface(iface3)
net2.add_interface(facility_port_interface)

# Submit Slice Request
try:
slice.submit()
except Exception as e:
print(f”Slice submission failed: {e}”)

Hello Hadi,

An announcement was posted earlier about FIU dataplane down which could be affecting your experiment. Updates should be posted on this thread about when it will be fixed:

FABRIC FIU Dataplane connection is down

Best,

Benjamin
