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
