Configuring Spanning Tree Protocol (STP) and Advanced STP Features
HP9300(config)# spanning-tree priority 0
The command in this example changes the priority on a device on which you have not configured port-based
VLANs. The change applies to the default VLAN. If you have configured a port-based VLAN on the device, you
can configure the parameters only at the configuration level for individual VLANs. Enter commands such as the
following:
HP9300(config)# vlan 20
HP9300(config-vlan-20)# spanning-tree priority 0
To make this change in the default VLAN, enter the following commands:
HP9300(config)# vlan 1
HP9300(config-vlan-1)# spanning-tree priority 0
Syntax: [no] spanning-tree [forward-delay <value>] | [hello-time <value>] | [maximum-age <value>] | [priority
<value>]
The forward-delay <value> parameter specifies the forward delay and can be a value from 4 – 30 seconds. The
default is 15 seconds.
NOTE: You can configure an HP device for faster convergence (including a shorter forward delay) using Fast
Span or Fast Uplink Span. See "Configuring Advanced STP Features" on page 8-19.
The hello-time <value> parameter specifies the hello time and can be a value from 1 – 10 seconds. The default
is 2 seconds.
NOTE: This parameter applies only when this device or VLAN is the root bridge for its spanning tree.
The maximum-age <value> parameter specifies the amount of time the device waits for receipt of a hello packet
before initiating a topology change. You can specify from 6 – 40 seconds. The default is 20 seconds.
The priority <value> parameter specifies the priority and can be a value from 0 – 65535. A higher numerical
value means a lower priority. Thus, the highest priority is 0. The default is 32768.
You can specify some or all of these parameters on the same command line. If you specify more than one
parameter, you must specify them in the order shown above, from left to right.
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.
