Note
A port that is not participating in spanning tree is immediately
placed in the forwarding state. It cannot be placed in the blocking
state by STP should there be a loop in the network topology.
Consequently, it is incumbent on the network administrator to
insure that no loop will develop should STP be disabled on a port.
Note
A change to the port priority parameter takes effect immediately. A
change to the port cost value requires you to reset the switch. A new
port cost value is not implemented until the unit is reset.
Description
This command is used to set the following parameter settings for STP on
the switch ports:
❑ Port cost
❑ Port priority
❑ Fast mode
Examples
The following command sets the port cost to 15 and the port priority to
100 on Port 6:
set stp port=6 portcost=15 portpriority=100
The following command activates fast mode on Port 10:
set stp port=10 fastmode=enabled
