One of the modules there can extract probable neighbour information
from some nortel devices.
I find reference to NDP (Nortel Discovery Protocol) in a few places
but it seems almost spurious as there is no technical information
under that name.
There is an (almost?) standardized Link Layer Discovery Protocol (LLDP)
that I find some hints that some Nortel devices support.
