Hi,

When i set vlan_mode native-untagged or access as option on our bond0 interface
Openvswitch sends LACP packets still out as 802.1Q with a VLAN 0 tag.


On our switch:
17:41:22.773956 00:1c:73:13:a5:d9 (oui Arista Networks) > 01:80:c2:00:00:02 (oui Unknown), ethertype Slow Protocols (0x8809), length 124: LACPv1, length 110

From the documentation:


https://man7.org/linux/man-pages/man7/ovs-actions.7.html

2.  VLAN output processing: This stage adjusts the packet
                  to represent the VLAN in the correct way for the
                  output port. Its behavior varies based on the
                  vlan-mode in the output port’s Port record:

                  trunk
                  native-tagged
                  native-untagged
                       If the packet is in VLAN 0 (for native-untagged,
                       if the packet is in the native VLAN) drops any
                       802.1Q header. Otherwise, ensures that there is
                       an 802.1Q header designating the VLAN.

                  access
                       Remove any 802.1Q header that was present.




How can i remove this VLAN 0 tag / 802.1Q for LACP packets?


Have a nice day.

thanks!
