set spantree
portcost
Changes the cost that transmission through a network port or ports in
the default VLAN on a wireless LAN switch adds to the total cost of a
path to the STP root bridge.
Syntax —
set spantree portcost port-list cost cost
■ port-list — List of ports. MSS applies the cost change to all the
specified ports.
■ cost cost — Numeric value. You can specify a value from 1 through
65,535. STP selects lower-cost paths over higher-cost paths.
Defaults — The default port cost depends on the port speed:
■ 10Mbps — the default is 100.
■ 100Mbps — the default is 19.
■ 1000Mbps — the default is 4.
Access — Enabled.
History — Introduced in MSS Version 3.0.
Usage — This command applies only to the default VLAN (VLAN 1). To
change the cost of a port in another VLAN, use the set spantree
portvlancost command.
Examples — The following command changes the cost on ports 3 and 4
to 20:
WX1200# set spantree portcost 3,4 cost 20
success: change accepted.
