Installation and Basic Configuration Guide
Enabling or Disabling 802.1W on a Single Spanning Tree
To enable 802.1W for all ports of a single spanning tree, use the procedure in this section.
USING THE CLI
Enter a command such as the following:
HP9300(config-vlan-10)# spanning-tree single 802-1w
Syntax: [no] spanning-tree single 802-1w
USING THE WEB MANAGEMENT INTERFACE
You cannot enable or disable 802.1W on a single spanning tree using the Web management interface.
Disabling or Enabling 802.1W on an Individual Port
The sp anni ng-t r e e 80 2-1 w or sp anni ng-t r ee si ngl e 802-1w command must be used to initially enable 802.1W
on ports. Both commands enable 802.1W on all ports that belong to the VLAN or to the single spanning tree.
Once 802.1W is enabled on a port, it can be disabled on individual ports. 802.1W that have been disabled on
individual ports can then be enabled as required.
NO TE: If you change the 802.1W state of the primary port in a trunk group, the change affects all ports in that
trunk group.
USING THE CLI
To disable or enable 802.1W on an individual port, enter commands such as the following:
HP9300(config)# interface 1/1
HP9300(config-if-1/1)# no spanning-tree
Syntax: [no] spanning-tree
USING THE WEB MANAGEMENT INTERFACE
You cannot enable or disable 802.1W on individual ports using the Web management interface.
Changing 802.1W Bridge Parameters
When you make changes to 802.1W bridge parameters, the changes are applied to individual ports on the bridge.
To change 802.1W bridge parameters, use the following methods.
USING THE CLI
To designate a priority for a bridge, enter a command such as the following:
HP9300(config)# spanning-tree 802-1w priority 10
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 802-1w priority 0
To make this change in the default VLAN, enter the following commands:
HP9300(config)# vlan 1
HP9300(config-vlan-1)# spanning-tree 802-1w priority 0
Syntax: spanning-tree 802-1w [forward-delay <value>] | [hello-time <value>] | [max-age <time>] | [force-version
<value>] | [priority <value>]
The f o r w ar d-del a y <value> parameter specifies how long a port waits before it forwards an RST BPDU after a
topology change. This can be a value from 4 – 30 seconds. The default is 15 seconds.
