MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

SPANNING TREE PROTOCOL (STP)

CHAPTER 12: SPANNING TREE PROTOCOL (STP)

Example 12-3 shows how to enable STP using the above commands.

The

priority

command specifies the port or switch level priority. When a port(s) are

specified the priority is associated with ports and their value is 0 to 255. If no ports are
specified, then the switch (bridge) priority is specified and its value is 0 to 65535. This value
is used along with the switch MAC address to determine which switch in the network is the
root device. Lower values mean higher priority. The default value is 32768.
