Enabling or Disabling RSTP. Issuing the command to enable Spanning Tree on the switch imple-

Spanning Tree removes protection against redundant network paths.

Abbreviation: [no] span

using the “no” option, without losing the most-recently configured parameter settings.

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

for more information on the STP version and its parameters.
