Table 9.4: STP Disable and Reset Commands

if all VLANs were deleted from it. The default
STPD, s0, cannot be deleted.
disable ignore-stp vlan <name> Allows a VLAN to use STP port information.
disable stpd [<stpd_name> | all] Disables the STP mechanism on a particular STPD
or for all STPDs.
disable ignore-bpdu vlan <vlan-name> Disables the ignoring of Bridge Protocol Data Units
(BPDUs) on a VLAN.
disable stpd port <portlist> Disables STP on one or more ports. Disabling STP
on one or more ports puts those ports in forwarding
state; all BPDUs received on those ports are
disregarded.

to all STPDs.
