z
Configure PVST+ edge port with optional Bridge Port Data Unit (BPDU) guard, VLAN, port priority,
and port cost on an interface.
Syntax
spanning-tree pvst [edge-port [bpduguard [shutdown-on-violation]] | vlan vlan-range
{cost number | priority value} ]
To disable PVST+ on an interface, use the no spanning-tree pvst [edge-port [bpduguard]
[shutdown-on-violation]] | vlan vlan-range {cost number | priority value} ] command.
Parameters
spanning-tree pvst Configure PVST+ on an interface.
S6000
edge-port (OPTIONAL) Enter the keyword edge-port to configure the interface as a PVST+
edge port.
bpduguard (OPTIONAL) Enter the keyword portfast to enable Portfast to move the interface
into forwarding mode immediately after the root fails.
Enter the keyword
bpduguard to disable the port when it receives a BPDU.
shutdown-on-

(OPTIONAL) Enter the keyword shutdown-on-violation to hardware disable an
interface when a BPDU is received and the port is disabled.
vlan vlan-range (OPTIONAL) Enter the keyword vlan followed by the VLAN number(s).
