To disable STP or return STP settings to their defaults, use the commands listed in Table 7-2.

Table 7-2:STP Disable and Reset Commands

Command

Description

delete stpd <stpd_name>

disable stpd [<stpd_name> all]

disable stpd port <portlist>

Removes an STPD. An STPD can only be removed if all VLANs have been deleted from it.

Disables the STP mechanism on a particular STPD, or for all STPDs.

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.

unconfig stpd {<stpd_name> all}	Restores default STP values to a particular STPD or
	to all STPDs.
