The cost command is port specific. A path cost is assigned to individual ports for the
switch to determine which ports are the forwarding points. A higher cost means the link is
“more expensive” to use and falls in the passive mode compared to the link with a lower
cost. Value ranges from 0 to 65535, with a default value of 32768.

value=<0-65535>
The port command assigns ports to STP. If you are unsure, let the software make the
decisions. The status parameter enables or disables a port from participating in STP
discovery. Its best to only allow trunk ports to participate in STP. End stations need not
participate in STP process.

status=<enable|disable>
The timers command changes the STP forward delay, hello timer and aging timer values.
The
forward-delay
parameter indicates the time duration the switch will wait from
listening to learning states and from learning to forwarding states. The value ranges from
4 to 30 seconds with a default value of 15. When the switch is the root device, the
hello
parameter represents the time between messages being transmitted. The value is from 1
to 10 seconds with a default value is 2. The
age
parameter is the maximum time a
message with STP information is allowed by the switch before the switch discards the
information and updates the address table again. Value ranges from 6 to 40 seconds with
default value of 20.
