12–6 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
ML1600# show active-stp
Current Active Mode: RSTP.
RSTP is Disabled.
ML1600# stp
ERROR: Invalid Command
ML1600# set stp type=stp
STP Mode set to STP.
ML1600# stp
ML1600(stp)##
stp enable
Successfully set the STP status
ML1600(stp)## show stp config
