This gives the impression in conjunction with OP that there is agreement
that fxp has been replaced by em. I'm not sure if that implication was
intended or not.
However that is not true, fxp are on-band dedicated management ethernet
(please JNPR, take page from CSCO and roll proper oob ethernet, like CMP).
While em are used for internal signalling.
And current RE model uses both, but obviously for different purpose.
