Hi All,
I am trying to configure vlan stacking (802.1ad) to few ovs bridge ports, in
Normal mode bridge operation. I am using ovs-master code
Version 2.3.9 for my experiments.
I am seeing no support for stacked vlans both from the configuration interface
perspective and datapath as well.
I am trying to come up with the design and implementation of configuration
interface support for 802.1ad (ovs-vsctl) and also datapath support.
Currently as I understand ovs-vsctl vlan configuration has the following modes
defined in ovsdb: access, native−tagged, native−untagged, and trunk.
I have the following configuration in my mind for 1ad support.
1.Access port :
Adds C-VLAN ,does 802.1q tagging as usual, Ex: tag =10)
3.Trunk port without qinq support : On ingress by default
receives all vlan tagged traffic(single) , sends the same out of egress.
(double tagged traffic currently misbehaving)
4.Trunk port with qinq support : On ingress adds a
specific S-VLAN for a specific customer. On egress pops S-VLAN.
As I understand access port doesn’t require qinq support , so supporting the
same for trunk ports only
It would be really helpful , if you could let me know your suggestions and
comments towards my approach. Also let me know how the ovs community is
approaching towards
802.1ad, So that it will be in sync with ovs community thoughts.
Version 11 of the 802.1ad patch was submitted about 1 week ago. I am
currently working on version 12 which incorporates some comments from
reviewers.
Also I am seeing multiple patches for 1ad support in datapath, though few not
working for me. Please, let me know if any working patch is available that
would greatly save my
time in this experiment.
Please send information about what version of the patch you tried and
with information about the failure case.
Thanks in Advance,
Uday
