Looking at the documentation, https://www.openvswitch.org/support/dist-docs/ovs-vswitchd.conf.db.5.html, you can limit this by setting the correct VLAN assignment: output_vlan: optional integer, in range 1 to 4,095 Output VLAN for selected packets, if nonempty. The frames will be sent out all ports that trunk output_vlan, as well as any ports with implicit VLAN output_vlan. When a mir‐ rored frame is sent out a trunk port, the frame’s VLAN tag will be set to output_vlan, replacing any existing tag; when it is sent out an implicit VLAN port, the frame will not be tagged. This type of mirroring is sometimes called RSPAN. ... > ** Add in any methods to use DPDK accelerations/offloads. > > -Fred > >> On Oct 17, 2023, at 2:58 AM, Eelco Chaudron <echau...@redhat.com> wrote: >> >> >> >> On 16 Oct 2023, at 17:12, Fred Licht via discuss wrote: >> >>> Hi All, >>> I am looking for suggestions/advice on how to setup a configuration.
