  • Mark Combs thinks this is interesting:

To disable autonegotiation on a Cisco switch port, you simply need to statically configure the speed and the duplex settings.


Cover of CCIE Routing and Switching v5.0 Official Cert Guide, Volume 1, Fifth Edition

Which is correct? Speed will always negotiate so is the paragraph wrong?
