• Path Cost – This parameter can be used to assign a higher or lower path cost to a port. This value can be
used to bias traffic toward or away from a certain path during periods of rerouting. For example, if you wish to
bias traffic away from a certain port, assign it a higher value than other ports within the VLAN or all other ports
(when VLANs are not active on the Routing Switch). Possible values are 0 – 65535. The default values are
listed in Table 6.3.

USING THE CLI
EXAMPLE:
Suppose you want to enable STP on a system in which no port-based VLANs are active and change the hello-
time from the default value of 2 to 8 seconds. Additionally, suppose you want to change the path and priority costs
for port 5 only. To do so, enter the following commands.
HP9300(config)# span hello-time 8
HP9300(config)# span ethernet 5 path-cost 15 priority 64
Here is the syntax for global STP parameters.
Syntax: span [forward-delay <value>] | [hello-time <value>] | [maximum-age <time>] | [priority <value>]
Here is the syntax for STP port parameters.
Syntax: span ethernet <portnum> path-cost <value> | priority <value>
USING THE WEB MANAGEMENT INTERFACE
To modify the STP parameters:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to display the configuration options.
3. Select the STP link to display the STP bridge and port parameters.
