2-­‐8.3 MSTI Priorities
When you implement a Spanning Tree protocol on the switch in the bridge instance, the CIST is the
default and is always active. To control the bridge priority, lower numeric values have better priority.
The bridge priority plus the MSTI instance number, concatenated with the 6-­‐byte MAC address of the
switch, forms a Bridge Identifier.
The section describes how to inspect the current STP MSTI bridge instance priority configurations, and
possibly change them.
Web Interface

1.

3. Click Save to save the setting.
