Description

This command sets the CIST priority number on the switch. This number is used in determining the root bridge for the bridged network. The bridge with the lowest priority number acts as the root bridge. If two or more bridges have the same priority value, the bridge with the numerically lowest MAC address becomes the root bridge.To view the current CIST priority number, see SHOW MSTP on page 429.
