General Attributes parameters

Parameter	Description	Default Value	Acceptable Values
Spanning Tree Name	Enter a name for the spanning tree. The spanning tree name should begin with an alphabet.	Spanning Tree	A to Z a to z 0 to 9 space
Spanning Tree Type	Select the spanning tree type from the drop down options. CSTP: Protocol defined by IEEE 802.1-1D standard; a Layer 2 link management protocol that prevents loops in the network. RSTP: Protocol defined by IEEE 802.1-1W standard; is the rapid convergence of ports to a forwarding state. MSTP: Protocol defined by IEEE 802.1-1S standard; is an extension of the RSTP protocol and allows for the independent configuration as a separate spanning tree for each VLAN group. This feature is not supported in this product release.	RSTP	CSTP MSTP RSTP
