What am I doing wrong?
vlan_tci=0xffe/0x1fff looks confused, to me. It cannot ever match any packets, because it looks for a packet with no VLAN header (because bit 12 is not set in the value) but a nonzero VLAN ID (because bits 0-11 are nonzero in the value). I imagine that the root of the problem, though, is that (based on bit 12 of vlan_tci) the flow's packets have no VLAN yet the actions are trying to strip a VLAN header. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
