Quantum / Folsom - Traffic is not tagged when leaving interfaces

My interface doesn't see any tagget traffic leaving it even though it says so using dump-flows on the bridge that it should.

My switch is configured with LACP and VLAN 60-100 in tagget mode.

Rather speaking Salvatore if I try to ping .1 or .2 which is the l3 / router and dhcp address from the VM it can't be pinged.

This is what I see on the controller: 00:00:00.000000 fa:16:3e:6a:97:92 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 46: vlan 60, p 0, ethertype ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 172.16.59.1 tell 172.16.59.5, length 28

Compute dump:

00:00:00.000000 fa:16:3e:6a:97:92 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 46: vlan 60, p 0, ethertype ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 172.16.59.1 tell 172.16.59.5, length 28

The VLAN stuff seems to be working fine but there's no real traffic that works since ICMP isn't getting though.

Hi Endre,

Maybe it's related to the vlan FAQ here http://openvswitch.org/cgi-bin/gitweb...

From your pastebin: #------- os-svc02.os.lan OpenVSwitch Flow Dump (ofctl dump-flows br-virtual) -------# NXST_FLOW reply (xid=0x4): cookie=0x0, duration=132980.405s, table=0, n_packets=6, n_bytes=468, priority=2,in_port=2 actions=drop cookie=0x0, duration=132915.083s, table=0, n_packets=841, n_bytes=101410, priority=4,in_port=2,dl_vlan=1 actions=mod_vlan_vid:60,NORMAL cookie=0x0, duration=132914.768s, table=0, n_packets=0, n_bytes=0, priority=4,in_port=2,dl_vlan=2 actions=mod_vlan_vid:62,NORMAL cookie=0x0, duration=132983.387s, table=0, n_packets=15591, n_bytes=1723753, priority=1 actions=NORMAL

This configuration looks fine to me. On cmp02 tagging rules are not present because no ports are create on br-int.

I am not aware of any issues with OVS tagging and bond interfaces, even if it would be worth checking. Also, I've noticed that on svc-02 br-virtual is connected to eth1 whereas on the other two it's connected to bond0. Is there a chance this might be related to the problem you're seeing?
