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

1 2 ... 35 36 37 38 39 40 41 42 43 44 45 ... 303 304
