fa0/0 versus f0/0 syntax

Unanswered Question
Feb 19th, 2007

I've been away from Cisco routers for a while, and I've spent hours trying to find where this new FastEthernet interface syntax of "fa0/0" came from. Is that "a" the second letter of "Fast", or does it mean "aggregate" or something to do with trunking or VLANs.

I have this problem too.

The "a" is there because it is the second letter in fast. Fa is an abbreviation of fast (or an abbreviation of fastethernet - depending on how you want to look at it).

Welcome back to the world of Cisco routers.
