Hi Guys, Thanks for your response. Just to be clear can this be done by running ovs-vswitchd, setting up mirroring using ovs-vsctl and then setting up/modifying some flows using ovs-ofctl (assuming ovs-ofctl can be used along with ovs-switchd). Or do I need to go with ovs-openflowd and then defining all the flows using ovs-ofctl/open flow primitives for a learning bridge and then for the policy based port mirroring.
Thanks in advance.
