MSTI Priorities
When you implement a Spanning Tree Instance on the Switch the CIST is the default Instance which is always active and
controls the Bridge Priority. MSTI Priorities allows you to configure the Priority of the MSTI Instances of the Switch. The
Priority value is Descending (i.e. 100 has a higher priority than 1000).
To configure MSTI Priorities, select Configuration > Spanning Tree > MSTI Priorities from the navigation menu.
MSTI Configuration
MSTI: Displays the bridge instance, CIST is the default instance and is always active.
Priority: Allows you to set the Bridge Priority per Instance Priority. Value is descending (i.e. 100 has a higher priority than
1000). It is typically recommended to keep the MSTI Instance Priority lower than the CIST Priority.
