enters forwarding state (see "Displaying Interface Settings for
STA" ).
BPDU Guard – This feature protects edge ports from receiving BPDUs.
It prevents loops by shutting down an edge port when a BPDU is
received instead of putting it into the spanning tree discarding state. In
a valid configuration, configured edge ports should not receive BPDUs.
If an edge port receives a BPDU an invalid configuration exists, such as
a connection to an unauthorized device. The BPDU guard feature
provides a secure response to invalid configurations because an
administrator must manually enable the port. (Default: Disabled)
BPDU Filter – BPDU filtering allows you to avoid transmitting BPDUs
on configured edge ports that are connected to end nodes. By default,
STA sends BPDUs to all ports regardless of whether administrative edge
is enabled on a port. BDPU filtering is configured on a per-port basis.
(Default: Disabled)
