configured spanning-tree operation on the switch, execute
spanning-tree.
Note: When you activate spanning-tree operation or change
the spanning-tree configuration while spanning tree is
enabled, the switch must recalculate the network paths it
uses.To minimize traffic delays while this convergence occurs,
HP recommends that you not activate spanning tree operation
until you have finished configuring all devices in your
network. Refer to “Enabling an Entire MST Region at Once or
Exchanging One Region Configuration for Another” on
page 6-72.
Note The following commands are available only when the switch is configured for
MSTP protocol operation.
