Blocked Port Name of a blocked port.
Reason
Reason that the port was blocked:
• Root-Protected—Root guard function.
• Loop-Protected—Loop guard function.
• Loopback-Protected—Self-loop protection. A port in the MSTI receives a BPDU that
it sends.

Parameters
interface interface-type interface-number: Displays the BPDU statistics on a specified port, where
interface-type interface-number indicates the port type and number.
instance instance-list: Displays the BPDU statistics of the MSTIs that are specified by an instance list, in the
format of instance-list = { instance-id [ to instance-id ] }&<1-10>, where &<1-10> indicates that you can
specify up to 10 instances or instance ranges. The value range for the instance-id argument is 0 to 4094,
and the value 0 represents the CIST.
