I've been labeling all my diagrams using Fe as an abbreviation for FastEthernet. And know I see a colleauge using Fa instead.
Are the two interchangeable? Is one for a router and the other for a switch? Is one for the way it looks on the back of the router and the other for commands?
It is quite reasonable to choose the abbreviation as FastEthernet or asFAstEthernet. (FE equivalent to FA)
So as Edison says yes the abbreviations are quite interchangeable.
