Examples # In MSTP mode, display information about ports that are blocked by spanning tree protection functions. display stp abnormal-port MSTID Blocked Port Reason 1 FortyGigE1/1/1 Root-Protected 2 FortyGigE1/1/2 Loop-Protected 12 FortyGigE1/1/3 Loopback-Protected Table 23 Command output Field MSTID Blocked Port Reason Description MSTI of the blocked port. Name of a blocked port. 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. display stp bpdu-statistics Use display stp bpdu-statistics to display the BPDU statistics on ports. Syntax display stp bpdu-statistics [ interface interface-type interface-number [ instance instance-list ] ] Views Any view Predefined user roles network-admin network-operator 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 ] }&, where & 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. 102
