I tried to inject a flow using Open vswitch Command. I have been able to redirect it to proper Ethernet port. I checked through wireshark and I am also receiving UDP packets at the intended machine's receiver ethernet port. However, IP and mac dest are not changed in the packets. following is my added flow.
root@my-lap:~/mininetScripts$ sudo ovs-ofctl add-flow s1 "table=0, priority=200, in_port=4, dl_vlan=65535, dl_src=9e:13:f8:e8:cb:c7 dl_dst=1e:f6:b5:ac:e9:b1, actions=output:5,mod_nw_dst:10.0.0.6,mod_dl_dst=ea:70:c4:0b:15:cb" root@my-lap:~/mininetScripts$ sudo ovs-ofctl dump-flows s1 NXST_FLOW reply (xid=0x4): cookie=0x0, duration=118.034s, table=0, n_packets=124, n_bytes=5680, idle_age=1, priority=200,in_port=4,vlan_tci=0x0000,dl_src=9e:13:f8:e8:cb:c7,dl_dst=1e:f6:b5:ac:e9:b1 actions=output:5,mod_nw_dst:10.0.0.6,mod_dl_dst:ea:70:c4:0b:15:cb root@my-lap:~/mininetScripts$ On 7 January 2014 01:23, hardik soni <[email protected]> wrote: > Thanks Justin for giving the specific command. > Thanks for L2 destination remark, I totally missed it. > > yes, I meant destination TCP/UDP port as destination transport. > > > On 7 January 2014 01:03, Justin Pettit <[email protected]> wrote: > >> If by "destination transport", you mean the TCP/UDP port, then you can do >> what you describe.
