Spanning-Tree Operation
Configuring Rapid Reconfiguration Spanning Tree (RSTP)
Figure 6-4. Example of the Spanning Tree Configuration Display (HP Series 3400cl Switch)
Enabling or Disabling RSTP. Issuing the command to enable spanning
tree on the switch implements, by default, the RSTP version of spanning tree
for all physical ports on the switch. Disabling spanning tree removes protec­
tion against redundant network paths.
Syntax:
[no] spanning-tree
Abbreviation:
[no] span
This command enables spanning tree with the current parameter settings or
disables spanning tree, using the “no” option, without losing the most-recently
configured parameter settings.
Enabling STP Instead of RSTP. If you decide, for whatever reason, that
you would prefer to run the IEEE 802.1D (STP) version of spanning tree, then
issue the following command:
Syntax:
spanning-tree protocol-version stp
Abbreviation:
span prot stp
For the STP version of spanning tree, the rest of the information in this section does not apply. Refer
to “802.1D Spanning-Tree Protocol (STP)” on page 6-21 for more information on the STP version and
its parameters.
