- New support for multiple VLANs (802.1ad or "QinQ"), including a new
"dot1q-tunnel" port VLAN mode.
+ - In ovn-vsctl and vtep-ctl, record UUIDs in commands may now be
+ abbreviated to 4 hex digits.
- OVN:
* IPAM for IPv4 can now exclude user-defined addresses from assignment.
* IPAM can now assign IPv6 addresses.
* Allow ovn-controller SSL configuration to be obtained from vswitchd
database.
* ovn-trace now has basic support for tracing distributed firewalls.
+ * In ovn-nbctl and ovn-sbctl, record UUIDs in commands may now be
+ abbreviated to 4 hex digits.
- Add the command 'ovs-appctl stp/show' (see ovs-vswitchd(8)).
- OpenFlow:
* Increased support for OpenFlow 1.6 (draft).
