The value of instance-id ranges from 0 to 32, where 0 represents the CIST. |: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide. begin: Displays the first line that matches the specified regular expression and all lines that follow. exclude: Displays all lines that do not match the specified regular expression. include: Displays all lines that match the specified regular expression. regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters. Description Use display stp bpdu-statistics to display the BPDU statistics on ports. In MSTP mode, follow these guidelines: • 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 or RSTP mode, follow these guidelines: • If you do not specify any port, this command displays the BPDU statistics of on all ports. The displayed information is sorted by port name. 95
