Hi,
I have a question regarding the behaviour of the drop action.
The FAQ states:
"An empty set of actions causes a packet to be dropped. You can
specify an empty set of actions with "actions=" on the ovs-ofctl
command line".
So, for example if I add a flow using ofctl, specifying the action as 'drop', I
assume that a flow table entry, consisting of the flow key and an empty actions
field is added to the vswitchd's flow table.
In terms of how the drop action actually works, is there an explicit DROP
action that is executed for flows that match this flow entry (similar to the
PUSH_VLAN, OUTPUT, SET, etc. actions), and if not, what is the mechanism by
which packets are dropped?
Thanks,
Mark
