[mininet-discuss] Setting iperf source port

I do not think you can change it without modifying the system implementations.
ps:This is not a problem about mininet.

Recommendations for Transport-Protocol Port Randomization
   The IP address and
   port number of the client are normally left unspecified by the client
   application and thus are chosen automatically by the client
   networking stack.  Ports chosen automatically by the networking stack
   are known as ephemeral ports [Stevens

   While the server IP address, the well-known port, and the client IP
   address may be known by an attacker, the ephemeral port of the client
   is usually unknown and must be guessed.
