Hello,
I'm wondering if/how I can establish a relation between an OVS interface (such
as vnet0) and its port number as used in openflow entries?
Everything is working fine, I'm just trying to better understand how the
various components work together.
For example:
root@qemu-kvm:/# ovs-vsctl -V
ovs-vsctl (Open vSwitch) 1.11.90
Compiled May 8 2013 11:11:41
root@qemu-kvm:/#
root@qemu-kvm:/# ovs-ofctl dump-ports-desc br0
OFPST_PORT_DESC reply (xid=0x2):

5(vnet0): addr:fe:54:00:a5:77:73

6(vnet1): addr:fe:54:00:6b:64:ed

LOCAL(br0): addr:00:50:56:a5:50:44
config: 0
state: 0
speed: 0 Mbps now, 0 Mbps max
è Vnet0 appears to have port id 5 while vnet1 has port id 6. Now if I check the
fdb on br0 I get different port numbers:
root@qemu-kvm:/# ovs-appctl fdb/show br0
port VLAN MAC Age
2 0 00:18:74:c2:40:00 151
2 0 00:50:56:a5:28:9c 66
3 0 52:54:00:a5:77:73 1
4 0 52:54:00:6b:64:ed 1
root@qemu-kvm:/#
Flow entries match numbering found in the fdb:
root@qemu-kvm:/# ovs-ofctl dump-flows br0

root@qemu-kvm:/#
è Here I see ports 3 and 4 in use (they match the previous fdb output) for
vnet0 and vnet1
How come the numbers don't match? Now I noticed that only table Interfaces has
an ofport tuple, while table Port doesn't. Am I mixing interfaces and ports?
Thanks!
Chris.
