I just come across a lab that ask me to disable SPT. The full question is
Assume SW2 will never connect to switch or bridge. Disable Spanning Tree on this interface. You may not use "no spanning-tree" commands to do this. The interface must be up.
According to the above question, their solution is by using "spanning-tree bpdufilter" but my answer is "no switchport"
I just doubt whether they give me correct solution or not? "spanning-tree bpdufilter" just filter bpdu but not disable spt, I found that f0/15 is still participate in stp by using "show spanning-tree vlan 1" and found that f0/15 still there.
If I go with "no switchport", f0/15 is removed from show spanning-tree command result. yep, becuz it's already L3 port.
Any idea?
