Field Descri
p
tion
MST ID MSTI of the blocked port.
VLAN ID VLAN of the blocked port.
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.
• Disputed—Dispute protection. A port receives a low-priority BPDU from a
non-blocked designated port.
• InconsistentPortType-Protected—Inconsistent port type protection.
• InconsistentPvid-Protected—Inconsistent PVID protection.

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. They
are 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.
Usage guidelines
In MSTP mode:
• If you do not specify any MSTI or port, this command displays the BPDU statistics of all MSTIs on all
ports. The displayed information is sorted by port name and by MSTI ID on each port.
• If you specify a port but not an MSTI, this command displays the BPDU statistics of all MSTIs on the
port. The displayed information is sorted by MSTI ID.
• If you specify both an MSTI ID and a port, this command displays the BPDU statistics of the specified
MSTI on the port.
In STP, RSTP, or PVST mode:
