BPDU Guard Role
If I understand BPDU Guard is configured on Edge Ports along with Portfast.
Reading this Cisco artcile:
It does not say the Portfast has to be configured for BPDU Guard to have effect.
It also states:
you can configure BPDU Guard at the interface level regardless of the typ of the configuration.. what I understand from that, you can even configure it if the interface is a Trunk.
Any Expert to shade some lights on this topic?
