Yes but I wonder how much the v4 customers on that switch will appreciate 
it the day someone gets a DoS or even tries to do an FTP over IPv6. :) 
FastE is more than enough to do in a 3550 CPU.

Then again it's a lot easier than moving the v6 requesters to 3560s, and 
besides doing dual-stack on 3560s does bad things to your available v4 
TCAM. Some things you just can't win.
