[ovs-discuss] 回复： 回复： how to use ovs to controll one port's forward

[Alex Wang]

You can have a look of "man ovs-ofctl" and the "tutorial" directory,

An example of adding flow is:

ovs-ofctl add-flow [bridge_name] 'in_port=[OpenFlow port number], arp,
actions=drop'

[bridge_name]: the name of the bridge,
[OpenFlow port number]: can be obtained by the "ovs-ofctl show" command
The command will make the specified port drop all arp received.
There are more options listed in "man ovs-ofctl" with explanation, have a
look and apply what you need,
