             Summary:
             Calculates port indexes for both sides of edges in the networkx graph object. The lowest available index is always used.
-            Once used, port indexes are removed from the free_ports uplinks or downlinks list.
+            Once used, port indexes are removed from the free_port_indexes uplinks or downlinks list.
             Design principles of a Clos network define that port radix should be equal north and south.
             Max amount of uplink or downlink ports is 24.
             Exits if the number of port indexes required exceed the max, prompts user to reduce spine, tier2 or tier1 size.
