Can someone set me or Kyriakos or Murphy up with a HP to test this?
It is not very easy to debug without the ability to replicate the
problem.

1. Creates a lldp packet with the 6 least significant bytes of the dpid as a
tlv (see line 65 and 66 of discovery.py).
2. The received lldp packet's tlv field is then used to compute a chassis id
(line 276), this chassis id is only 6 bytes long
You are right. The problem is that you are unable
Hi Ali
The following three lines in the code ensure that the HP isn't
dropping the LLDP packets. So, it is not that issue.
# To insure that the LLDP src mac address is not a multicast
# address, since we have no control on choice of dpid
eth.src = '\x00' + struct.pack('!Q',dpid)[3:8]

Yeah, we've run into this before. Basically, the HP drops invalid
MACs (which are just treat as a string of bits).
KK, could you push this to revival?

Hi Ali
Could you please let us know what you meant by "does not work"?
Is the HP switch dropping the LLDP packet that is being packet-out?
The only problem we used to have with HP switches was that if the LLPD
src MAC was a multicast address, then the switch would drop it. This
has been fixed for

Awesome, thanks for the patch Dave.
Hi all,
I ran into a bug in discovery when it receives an LLDP packet with a
vlan tag, the matcher takes into account the fact that it has the VLAN
tag but the actual discovery code does not and throws an assertion
error. This was happening in the .4 branch

Yeah, I guess that doesn't make much sense. This should be simple to
fix. I'll do so tomorrow.
thanks.

Hi all,
Discovery seems to be sending out LLDP packets on the "local" OpenFlow
port. This seems a little odd to me as I would expect we're unlikely to
encounter any other switches on the local port.
