Hello vpp-devs, Has anyone looked at this?
Thanks, Juraj From: Juraj Linkes -X (jlinkes - PANTHEON TECHNOLOGIES at Cisco) Sent: Tuesday, 23 May, 2017 15:47 To: vpp-dev@lists.fd.io Cc: fds-...@lists.opnfv.org; Frank Brockners (fbrockne) <fbroc...@cisco.com>; Tomas Cechvala -X (tcechval - PANTHEON TECHNOLOGIES at Cisco) <tcech...@cisco.com>; Michal Cmarada -X (mcmarada - PANTHEON TECHNOLOGIES at Cisco) <mcmar...@cisco.com> Subject: Does VPP support vlan 0? Hi vpp-devs, I'm hitting an issue when VLAN ID is 0: 03:20:01:825468: tapcli-rx tap-0 03:20:01:825472: ethernet-input IP4: 00:25:b5:00:01:4a -> 01:00:5e:00:00:12 802.1q vlan 0 03:20:01:825473: error-drop ethernet-input: unknown vlan As I understand it, the device should treat packets with VLAN 0 as if it didn't have an ID: The null VLAN ID. Indicates that the tag header contains only priority information; no VLAN identifier is present in the frame. I'm trying this with 1704. Does VPP support this? Is there a workaround, like stripping the 802.1q header for tap ports? Thanks, Juraj
