Configuring the Switch To Use the 802.1D Spanning Tree Protocol
(STP). In the default configuration, the switch is set to RSTP (that is, 802.1w
Rapid Spanning Tree), and spanning tree operation is disabled. To reconfigure
the switch to 802.1D spanning tree, you must:
Change the spanning tree protocol version to stp.
1.
2. Use write memory to save the change to the startup-configuration.
3. Reboot the switch.
4. If you have not previously enabled spanning-tree operation on the switch,
use the spanning-tree command again to enable STP operation.
Syntax: spanning-tree protocol-version stp
write memory
boot
For example:
Figure 6-11. Steps for Changing Spanning-Tree Operation to the 802.1D Protocol
Enabling (or Disabling) Spanning Tree Operation on the Switch.
Syntax: [no] spanning-tree
This command enables (or disables) spanning tree operation
for either spanning tree version—STP/802.1D or RSTP/802.1w
(the default). (Default: Disabled.)
Before using this command, ensure that the version of
spanning tree you want to use is active on the switch. (See the
preceding topic, "Configuring the Switch To Use the 802.1D
Spanning Tree Protocol (STP)" on page 6-25.)
For example:
HPswitch spanning-tree
