pvstplus-protect
Prevents flooding and resulting port blocking on an interface when a Per-VLAN Spanning
Tree Plus (PVST+) packet is received on a port configured for Multiple Spanning Tree
Protocol (MSTP), blocking the PVST+ Bridge Protocol Data Unit (BPDU) and marking the
port as ERR-DISABLED.
Command Default
PVST+ Protect is disabled.
Modes
Interface configuration mode
Usage Guidelines
This command cannot be executed concurrently with the
pvst-mode command.
When you use the
pvstplus-protect command, you must also use the global
errdisable recovery pvstplus-protect command to enable ports to recovery from the error-disabled state.
The no form of the command disables PVST+ Protect.
Examples
The following example enables PVST+ Protect on a single port.
device(config)# interface ethernet 1/1/1 device(config-if-1/1/1)# pvstplus-protect
