MULTILINK ML1600 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
CONFIGURING STP
CHAPTER 12: SPANNING TREE PROTOCOL (STP)
Note
It is always a good idea to check which mode of STP is active. If the proper mode is not
active, the configuration command
stp
will not be understood. To set the proper mode,
use the
set stp
command.
Example 12-3 shows how to enable STP using the above commands.
Example 12-3: Enabling STP

Current Active Mode: RSTP.
RSTP is Disabled.
