Including inside a particular vendor's own implementation. For
instance some junipers advertise the interface name (ge-0/0/0) and
some the description ("To Bob's ISP") for the "interface name" field
in the CLI. So depending on the platform and version of code you
get totally different information from "show lldp neighbors".
It really makes it difficult to consume the data by script. Lots
of special cases.
