SDN Test Setup

1. Run mul

    sudo ./mul 
   

   This is the mul debug console

2. Log into MUL CLI

    telnet localhost 7000
   

3. [MUL CLI documentation] (https://github.com/openmul/openmul/blob/master/docs/openmul-CLI_GUIDE-basic.pdf)

4. Run mininet

    sudo mn --controller=remote,ip=127.0.0.1 --switch ovsk --topo linear,1
   

5. [Mininet CLI documentation] (http://mininet.org/walkthrough/#part-3-mininet-command-line-interface-cli-commands)

6. Run wireshark and capture lo0 interface

    sudo wireshark
   

7. Some useful commands:

• Mininet - network with 1 switch and 2 hosts

      sudo mn --controller=remote,ip=127.0.0.1 --switch ovsk 
          --topo single,2 -v debug --mac
  

• Mininet - network with a host per switch (2 switches, 2 hosts)

       sudo mn --controller=remote,ip=127.0.0.1 --switch ovsk 
           --topo linear,2 -v debug --mac
  

• Mininet - check for operation, ping

       h1 ping h2
       h1 ifconfig
  

• Mul -

• Mul - Add flows from VTY

       $ dpctl add-flow tcp:127.0.0.1:6633 in_port=1,actions=output:2
       $ dpctl add-flow tcp:127.0.0.1:6633 in_port=2,actions=output:1
  

• Mul - Controller configuration mode >enable #configure terminal (config)#mul-conf (mul-main)#

• Mul - Set a flow on a wildcard (0.0.0.0/0) or a specific host ip from mil-main config mode

       of-flow add switch 0x1 dip 0.0.0.0/0 sip 0.0.0.0/0 proto * tos * 
           dport * sport * smac * dmac * eth-type * vid * vlan-pcp * in-port * 
  

Add an action: (Add an action after the flow is added) (config-flow-action)# action-add vlan-id 2 (config-flow-action)# commit

View the flow on the switch: show of-flow switch
