2.2 Spanning Tree Protocol (STP) Commands
This section describes the commands you use to configure Spanning Tree Protocol
(STP). STP helps prevent network loops, duplicate messages, and network instability.
NOTE: STP is disabled by default. When you enable STP on the switch, STP
is still disabled on each port.
NOTE: If STP is disabled, the system does not forward BPDU messages.
2.2.1 spanning-tree
This command sets the spanning-tree operational mode to enabled.
Default disabled
Format spanning-tree
Mode Global Config
2.2.1.1 no spanning-tree
This command sets the spanning-tree operational mode to disabled. While disabled, the
spanning-tree configuration is retained and can be changed, but is not activated.
Format
no spanning-tree
Mode Global Config
2.2.2 spanning-tree bpdumigrationcheck
Use this command to force a transmission of rapid spanning tree (RSTP) and multiple
spanning tree (MSTP) BPDUs. Use the
<
unit/slot/port
>
parameter to transmit a BPDU
from a specified interface, or use the
all
keyword to transmit BPDUs from all
interfaces. This command forces the BPDU transmission when you execute it, so the
command does not change the system configuration or have a “no” version.
Format
spanning-tree bpdumigrationcheck {<unit/slot/port> | all}
Mode Global Config
