Syntax
mstp scope{all|pvst}
no mstp scope{all|pvst}
Command Default

No VLAN is under direct MSTP control.

Parameters
all
Configures MSTP on all VLANs.
pvst
Configures MSTP in per-VLAN spanning tree (PVST) mode.
Modes

Global configuration mode

Usage Guidelines

When the mstp scope all command is issued, the ports associated to VLANs in which any STP is configured transition to the blocking state. You must enter the mstp start command to re-converge the ports, VLANs, and VEs.

MSTP is not operational until the mstp start command is configured. You cannot start MSTP+ unless at least one MSTP+ instance of MSTP+ is configured.

The no form of this command removes the MSTP PVST mode and restores the device to non-MSTP mode.

Examples

The following example configures MSTP mode on all VLANs.

device(config)# mstp scope all

The following example enables MSTP in PVST mode.

device(config)# mstp scope pvst
