Purpose
Enters configuration mode.
Specifies the interface to configure, and enters the

• spanning-tree bpdufilter {enable | disable}
Enables or disables BPDU Filtering for the
specified spanning tree edge interface. By
default, BPDU Filtering is disabled.
• no spanning-tree bpdufilter
Enables BPDU Filtering on the interface if
the interface is an operational spanning tree
edge port and if you enter the spanning-tree
port type edge bpdufilter default command.
Exits interface mode.
(Optional)
Displays summary STP information.
(Optional)
Copies the running configuration to the startup
