Usage Guidelines
•
If an msti_id number is not specified, this command displays the Spanning Tree port operational status,
path cost, and role values for all associated MSTIs.
•
This is an explicit Spanning Tree command that displays Spanning Tree port information for an MSTI
regardless of which mode (1x1 or flat) is active on the switch.
•
Note that minimal information is displayed when this command is used in the 1x1 mode, as MSTIs are
not active in this mode. In addition, if MSTP is not the selected flat mode protocol, this command will
fail.
•
The configured keyword is only available when an instance number is specified with this command. In
addition, this keyword cannot be used in combination with either the forwarding or blocking
keywords.
•
Note that MSTI 0 also represents the CIST instance that is always present on the switch. To view the
CIST instance using this command, specify zero (0) for the
msti_id number.
