show spantree msti
Displays Spanning Tree bridge information for a Multiple Spanning Tree Instance (MSTI).
show spantree msti [msti_id]
Syntax Definitions
msti_id
An existing MSTI ID number (0-4094).
Defaults
Platforms Supported
OmniSwitch 6400, 6850, 6855, 9000, 9000E
Usage Guidelines
• If an msti_id number is not specified, this command displays the Spanning Tree status, protocol, and
priority values for all MSTIs.
• This is an explicit Spanning Tree command that displays Spanning Tree bridge 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, this command will fail if MSTP is not the selected flat mode proto-
col.
col.
• 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.
