Usage Guidelines
• This is an explicit Spanning Tree command that displays Spanning Tree port information for the flat
mode CIST instance 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 the CIST is
not active in this mode.
Examples
-> show spantree cist ports
