Parameters
instance instance-list: Displays the historical port role calculation information for 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.
slot slot-number: Displays the historical port role calculation information on the specified card.
slot-number represents the number of the slot that houses the card. If this option is not specified, this
command displays the historical port role calculation information on all cards. (MSR4000.)
Usage guidelines
In STP or RSTP mode, the displayed information is sorted by port role calculation time.
In MSTP mode:
• If you do not specify any MSTI, this command displays the historical port role calculation
information for all MSTIs. The displayed information is sorted by MSTI ID and by port role
calculation time in each MSTI.
• If you specify an MSTI, this command displays the historical port role calculation information for the
specified MSTI by the sequence of port role calculation time.
Examples
On an MSR2000 or MSR3000:
# In MSTP mode, display the historical port role calculation information for MSTI 2.
<Sysname> display stp instance 2 history
