Table 46: STP Disable and Reset Commands
Command Description
delete stpd <stpd_name> Removes an STPD. An STPD can only be removed if
all VLANs have been deleted from it. The default
STPD, s0, cannot be deleted.
disable ignore-bpdu vlan <name> Allows the switch to recognize STP BPDUs.
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 stpd ports <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 will be
disregarded.
