can ebtables be used to add/remove vlan tags
Hi,
Sorry if this is a duplicate post , I tried to post ebtables mail group and it pointed me here.
I created a vlan 0 interface using the vlan package and vconfig under linux . I'm just wanting to set the 8021p tags not segregate traffic. However I noticed that untagged traffic is is not being allowed thru the interface that I configured( in this case eth0.0). This seems like a bug in the VLAN module since VLAN 0 is a reserved id used to indicate priority tagged traffic so I would expect it to accept traffic tagged with VLAN 0 and untagged traffic.
In any case I'm trying to see if I can create a bridge with eth0.0 interface associated with the bridge and then use ebtables to add a VLAN priority tag to an incoming untagged packet so the packet will get processed. I also want to strip off the VLAN 0 traffic with priority 0 on outgoing traffic.
Based on my research this isn't possible and I would just like someone to confirm.
Thanks
Mark

Actually vconfig is considered deprecated. The best way to add/remove vlan's is with ip command.
ip link add link eth0 name eth0.1 type vlan id 1
I think you don't understand the behavior of the reserved vlan tag 0.

What I'm trying to do is to just add 8021p priority tags to traffic on a socket that has a certain priority set by a setsockopt call. I want the priority tags only set for this traffic. So basically I want priority tagged and untagged frames accepted on the interface. I realize VLAN 0 is for non vlan priority tagged traffic but it seemed to be the only way I could get outgoing traffic tagged with the set_egress_map.
Based on my research I did see any other way of getting packets priority tagged, am I missing something here ?
Thanks
