Subject: can ebtables be used to add/remove vlan tags
Date: Thu, 22 Sep 2011 10:27:38 -0600 [thread overview]
Message-ID: <4E7B61FA.7010403@dim.com> (raw)
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
