Layer 2 Network Topology with Edgecore Wedge100BF-32X P4 Tofino Switch on FABRIC

I have a question regarding the tutorial “Layer 2 Network Topology with Edgecore Wedge100BF-32X P4 Tofino Switch on FABRIC.”

I have been using this tutorial for a while and have been able to modify it for my own experiments. However, I have recently started experiencing problems with the setup.

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

# Create Network
net1 = slice.add_l2network(name=network1_name, subnet=IPv4Network(“192.168.0.0/24”))
net2 = slice.add_l2network(name=network2_name, subnet=IPv4Network(“192.168.0.0/24”))

# 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’)
net1.add_interface(iface1)
iface1.set_ip_addr(IPv4Address(“192.168.0.1”))

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

net1.add_interface(iface2)
net2.add_interface(iface3)

# Create Node 2 and its links
node2 = slice.add_node(name=node2_name, site=site1)
iface4 = node2.add_component(model=model, name=’nic1′).get_interfaces()[0]
iface4.set_mode(‘config’)
net2.add_interface(iface4)
iface4.set_ip_addr(IPv4Address(“192.168.0.2″))

# Submit Slice Request
slice.submit()”

Although the above code creates three nodes : “Node1”, “Node2”, and “P4”, for some reason it only displays one. Nevertheless, I am able to retrieve node information for Node1 and Node2 as shown below::

node1 = slice.get_node(“Node1”)
node2 = slice.get_node(“Node2”)
print(node1)
print(node2)

However, switch = slice.get_node("P4") returns a “not found” error, and I haven’t found a way to retrieve information about the switch. Strangely, the switch does appear in the slice’s graphical display.

To reiterate, I’ve been using this code without issues for months; the problem started today.

Thank you for help on this matter
