Hi Ben, Thanks for the quick reply!
Ok. How do I get the lldp packets through ovs to the lldp process? Initially I think they were dropped. ovs-appctl ofproto/trace br0 in_port=3,dl_dst=01:80:c2:00:00:0e,dl_type=0x88cc Bridge: br0 Flow: metadata=0,in_port=3,vlan_tci=0x0000,dl_src=00:00:00:00:00:00,dl_dst=01:80:c2:00:00:0e,dl_type=0x88cc Rule: table=0 cookie=0 priority=0 OpenFlow actions=NORMAL no input bundle, dropping Final flow: unchanged Megaflow: skb_priority=0,in_port=3,vlan_tci=0x0000/0x1fff,dl_src=00:00:00:00:00:00,dl_dst=01:80:c2:00:00:0e,dl_type=0x88cc Datapath actions: drop I then added ovs-vsctl set Bridge br0 other_config:forward-bpdu=true Now at least the packets aren’t getting dropped. ovs-appctl ofproto/trace br0 in_port=3,dl_dst=01:80:c2:00:00:0e,dl_type=0x88cc Bridge: br0 Flow: metadata=0,in_port=3,vlan_tci=0x0000,dl_src=00:00:00:00:00:00,dl_dst=01:80:c2:00:00:0e,dl_type=0x88cc Rule: table=0 cookie=0 priority=65535,dl_dst=01:00:00:00:00:00/ff:00:00:00:00:00 OpenFlow actions=ALL Final flow: unchanged Megaflow: skb_priority=0,in_port=3,dl_dst=01:00:00:00:00:00/ff:00:00:00:00:00,dl_type=0x88cc Datapath actions: 1,2,3 But the packets still don’t get counted by lldp. I think I need to add a flow, something like this: ovs-ofctl add-flow br0 priority=65535,dl_dst=01:80:c2:00:00:0e/ff:00:00:00:00:00,idle_timeout=0,actions=all But not sure what I should be setting action to?

On the wiki it says * IETF Auto-Attach SPBM and rudimentary required LLDP support Is there any documentation on this as it looks like a new feature on this latest release? This support is only going to be useful if you want to use Auto-Attach SPBM.
