Hi,
I’m running an OVS rpm (no source code) on RHEL 7.0
ovs-vswitchd (Open vSwitch) 2.3.1
Compiled Dec 26 2014 15:35:15
OpenFlow versions 0x1:0x1
Is there support in this version for LLDP?
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?
What exactly has to be configured to get LLDP working?
I have lldpad installed on my OS. When I send lldp packets to an interface
which is not connected to an ovs bridge, the lldp process receives the packets.
If lldp packets go through an ovs bridge, then the packets never make it to the
lldp process.
I can see from tcpdump, the lldp pkts coming in on the physical interface, but
lldptool doesn’t see any lldp packets. I also do not see any drops on the ovs
stats for the interface.
I have set other-config,
ovs-vsctl set Bridge br0 other_config:forward-bpdu=true
But that hasn’t helped either.
The interface in question is tied to an ovs bridge named br0, where enp130s0f0
is the physical interface,.
Bridge "br0"
Port "mgmt0"
Interface "mgmt0"
type: internal
Port "enp130s0f0"
Interface "enp130s0f0"
Port "br0"
Interface "br0"
type: internal
ovs_version: "2.3.1"
ovs-vsctl list bridge br0

What is rudimentary required LLDP support?
Thanks,
