Studying for 200-301.. just got through your STP Portfast/BPDUGuard video.
I'm curious as to why one would want to enable the PORTFAST and BPDUGUARD settings.
I understand the protections they provide. In the video you said they could be used instead of STP to decrease the time and resources used within the switch when connecting a port to something that will never need STP such as a workstation.
But when one considers how quickly RPVST moves, wouldn't it be safer (and fewer trouble tickets to recover) to use RPVST rather than take the chance that someone plugs the wrong type device into the wrong port? And as far as resources.. it would only happen when connecting a device to the port... mostly that happens one at a time. The only time that would REALLY be taxing is when the switch is powering up for some reason. And if the switch is already doing that.. there were bigger problems to worry about than a temporary crowding of resources. Right?
