History
Usage
The BPDU guard option prevents the port from participating in an active STP
Information
topology in case a BPDU appears on a port unintentionally, or is misconfigured, or
is subject to a DOS attack. This option places the port into the Error Disable state if
a BPDU appears, and a message is logged so that the administrator can take
corrective action. When BPDU guard and BPDU filter is enabled on the port, then
BPDU filter takes the highest precedence.

be configured as an edge port. Consider an edge port similar to a port with a
