Can anyone confirm that hard coded speed/duplex settings on a generic modern Cisco switch, will not prevent the switch port from sending fast link pulses, advertising the switch port's hardcoded speed/duplex settings so that the device at the other end, will be able to bring up a link if the remote device itself does not send out FLP?
Generic behaviour is that if you hard-code both speed and duplex, switch stops advertising to the other end using autoneg.
So 100/full fixed at one end and other end set to auto/auto, will result in that end thinking it is speaking to a hub that doesn't do autoneg, and it'll detect the 100, but will go to 100/half.
There are recent hw from the past 1-2 years that can advertise capabilities even when being fixed, but it has to be configured in another way.
