Hi,
I'm trying to use ovs-vswitchd and NOX together to control my
switches. I am not sure if I am doing this correctly, but it doesn't
work. So I was wondering if somebody could shed some light.
I use Ubuntu with 2.6.26 kernel. Everything compiles well and loads
well. Here's my ovs-vswitchd.conf file:
face.mybr.internal=true
bridge.mybr.port=eth1
bridge.mybr.port=eth2
bridge.mybr.controller=tcp:10.0.2.15:2525
bridge.mybr.datapath-id=000000000001
bridge.mybr.in-band=false
NOX is configured as an out-of-band controller, and connectivity is
fine. With this configuration file, I run ovs-vswitchd with -v, then I
get the log copied at the end of this email. It seems that there is no
error. However, when I actually bring up 2 hosts and try to ping each
other, ARP requests never pass through. I used tcpdump to verify that
either eth1 or eth2 receives the ARP requests, and they do receive the
packets.
Any help would be greatly appreciated. Thanks!
