[ovs-discuss] Match on vlan_vid

[Eder Leão Fernandes]

Hi,

I'm trying to match on vlan_vid using Open vSwitch, set as an OpenFlow 1.3
switch.
The flows are the following:

At table 0:  tag the packet, set the vid to 100 and send it to table 1.
$ sudo ovs-ofctl -O OpenFlow13 add-flow s1
table=0,in_port=1,actions=push_vlan:0x8100,set_field:100-\>vlan_vid,goto_table:1

At table 1: Match on in_port and vlan_vid, then output to port 2
$ sudo ovs-ofctl -O OpenFlow13 add-flow s1
table=1,in_port=1,vlan_vid=100,actions=output:2

Sending packets through the interface 1, the packets match the flow at
table 0, but do not match the flow at table 2.

This is the dump flows result
$ sudo  ovs-ofctl -O OpenFlow13  dump-flows s1
OFPST_FLOW reply (OF1.3) (xid=0x2):
 cookie=0x0, duration=94.936s, table=0, n_packets=7, n_bytes=294, in_port=1
actions=push_vlan:0x8100,set_field:100->vlan_vid,goto_table:1
 cookie=0x0, duration=75.93s, table=1, n_packets=0, n_bytes=0,
in_port=1,vlan_tci=0x0064/0x1fff actions=output:2

Reading the ofctl man page I can see that the vlan_tci  value shown by the
dump-flows looks right.

Am I doing something wrong?

Thanks.
