Usage Guideline
This is an explicit Spanning Tree command that displays Spanning Tree bridge 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. See second example below.
Examples
-> bridge mode flat
-> show spantree cist
