Join David Bombal for an in-depth discussion in this video sudo ovs-ofctl dump-flows s1, part of Practical Software-Defined Networking: 3 Learning Mininet.
- [Instructor] And let's dump the flows.…These are the flows currently programmed…by the controller…on the switch.…Now, in other videos in this course…I explained the flows in quite a bit of detail…but I'll just point out…that notice we have an idle_timeout and hard_timeout.…That determines when flows are removed.…The idle_timeout will expire…when there are no hits on the flow entry.…Then the flow entry's removed.…
Notice we have these entries for source…and destination Mac addresses,…so we have a source Mac address of this…which is this host on the left-hand side,…so scrolling up again, that's that host,…destination is this host on the right-hand side…over here, so the flow entry's essentially saying…that traffic with this source and this destination…will be sent out of port two.…The same is true for the reverse traffic,…so notice 77 as the source,…this host going to this destination of this host.…
Traffic will be sent out at port one over here.…These flow entries have a priority of 10,…so they'll take precedence over these flow entries…
