Changing STP Port Parameters
To change STP port parameters, use either of the following methods.
USING THE CLI
To change the path and priority costs for a port, enter commands such as the following:
HP9300(config)# vlan 10
HP9300(config-vlan-10)# spanning-tree ethernet 1/5 path-cost 15 priority 64
Syntax: spanning-tree ethernet <portnum> path-cost <value> | priority <value> | disable | enable
The ethernet <portnum> parameter specifies the interface.
The path-cost <value> parameter specifies the port's cost as a path to the spanning tree's root bridge. STP
prefers the path with the lowest cost. You can specify a value from 0 – 65535.
The default depends on the port type:
• 10 Mbps – 100
• 100 Mbps – 19
• Gigabit – 4
• 10 Gigabit – 2
The priority <value> parameter specifies the preference that STP gives this port relative to other ports for
forwarding traffic out of the spanning tree. You can specify a value from 8 – 252, in increments of 4. If you enter a
8 - 6
