Table 7-1:STP Configuration Commands

Command	Description
create stpd <stpd_name>	Creates an STPD. When created, an STPD has
	the following default parameters:
	■ Bridge priority — 32,768
	■ Hello time — 2 seconds
	■ Forward delay — 15 seconds
enable stpd [<stpd_name> all]	Enables the STP protocol for one or all STPDs.
	The default setting is disabled.
enable stpd port <portlist>	Enables the STP protocol on one or more ports.
	If STPD is enabled for a port, BPDUs will be
	generated on that port if STP is enabled for the
	associated STPD. The default setting is enabled.
config stpd <stpd_name> add vlan <name>	Adds a VLAN to the STPD.
config stpd <stpd_name> hellotime <value>	Specifies the time delay (in seconds) between
	the transmission of BPDUs from this STPD when
	it is the Root Bridge.
	The range is 1 through 10. The default setting is
	2 seconds.
config stpd <stpd_name> forwarddelay	Specifies the time (in seconds) that the ports in
<value>	this STPD spend in the listening and learning
	states when the switch is the Root Bridge.
	The range is 4 through 30. The default setting is
	15 seconds.
config stpd <stpd_name> maxage <value>	Specifies the maximum age of a BPDU in this
	STPD.
	The range is 6 through 40. The default setting is
	20 seconds.
	Note that the time must be greater than, or equal
	to 2 X (Hello Time + 1) and less than, or equal to
	2 X (Forward Delay –1).
config stpd <stpd_name> priority <value>	Specifies the priority of the STPD. By changing
	the priority of the STPD, you can make it more or
	less likely to become the Root Bridge.
	The range is 0 through 65,535. The default
	setting is 32,768. A setting of 0 indicates the
	highest priority.
