https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D240825 Bug ID: 240825 Summary: Vlan interfaces does not work on lagg from em0, em1 Product: Base System Version: 12.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: yar@shvets.name Created attachment 207816 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D207816&action= =3Dedit network configuration in rc.conf After upgrading from 11.3-RELEASE-p3 to 12.0-RELEASE-p10 vlan-interfaces on lagg0 (em0, em1) stopped working. Vlan interfaces look like working but not working. Network configuration is: em0 and em1 aggregated to lagg0. Based on lagg0 created vlan-interfaces. On the other end is a cisco switch (port channel from two ethernet ports, t= he mode is LACP). The network configuration worked on 9.x-releng, 10.x-releng, 11.2-releng, 11.3-releng. And does not work on 12.0-releng, 12-stable, 12.1-PRERELEASE. The lagg0 interface works. But does not work vlans on lagg0. Looks like that untagged ethernet frames passed from/to lagg0, but tagged ethernet frames not passed. After downgrading to 11.3-releng vlans on lagg0 works again. Kernel of the system based on GENERIC, i.e "device vlan" is in the kernel configuration. See rc.conf, console.log in attachment. --=20 You are receiving this mail because: You are the assignee for the bug.=
