What is the difference between these two commands?
set spantree bpdu-guard mod/port {enable | disable | default}
set spantree portfast bpdu-guard mod/port {enable | disable | default}

None as far as I know (I'm not catos expert though). Bpduguard was initially based on portfast. It was subsequently modified to be *not* dependent on portfast (at least for its port configuration). I guess the portfast version should be deprecated.

Well as far as i know,if the portfast is applied on the access port and you connect a switch ,there is scope for loop to exists since the port direcly goes into forwarding state,if we apply bpdu guard along with the portfast ,the port will go into err-disable as soon as it will receive a BPDU.
