Enables Per-VLAN Spanning Tree Plus (PVST+) support on a port immediately.

pvst-mode
no pvst-mode

PVST+ support is automatically enabled when the port receives a PVST BPDU.

Interface configuration mode

This command cannot be executed concurrently with the pvstplus-protect command.

If you disable PVST+ support, the software still automatically enables PVST+ support if the port receives a BPDU with the PVST+ format.

The no form of the command disables the PVST+ support.

The following example shows how to enable the PVST+ mode. 

device(config)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# pvst-mode
