Hi,
I've encountered an issue like this before with flowvisor and the discovery
module. The easiest thing to do is to change the lldp value in
./src/nox/lib/packet/ethernet.py
#LLDP_TYPE = 0x88cc
LLDP_TYPE = new_value
then add this new_value, ether_type to your slice.
Hopefully that will do the trick.
