Built-in Commands

stpForceVersion

Description:	Puts Spanning Tree into STP compatibility mode (0) or the default RSTP
	mode (2).

Syntax:	stpForceVersion [ 0 2 status ]

Options:	stpForceVersion 0 – Indicates STP compatibility.
	Enable stpForceVersion 0 only if the user does not want to “run 802.1w,”
	which does not allow transmission of RSTP BPDUs. The bridge will only
	transmit config BPDUs and TCNs. Therefore, to another bridge, it looks like
	it is running 802.1D (with few exceptions). This is only used if the potential of
	looping for 3 seconds (the time it takes a bridge to determine it is connected to
	a legacy device) could not be tolerated. The necessity of using this
	configuration is rare.
	stpForceVersion 2 – Indicates RSTP support.
	Status – Displays current value.

Example:	-> stpForceVersion 2
	ForceVersion set to 2
