Status

	Hello Time:	Amount of time between configuration messages sent by the Spanning Tree algorithm
	Maximum Age	Amount of time before a configuration message is discarded by the system
	Forward Delay	Amount of time system spent transitioning from the ‘learning’ to the ‘listening’ to the ‘forwarding’
		states
	Bridge Priority	Priority setting among other switches in the Spanning Tree
	Cost & Priority:	Refer to the following table for complete information
	Parameters	Range		Description
	Prty (Priority)	0-240		STP uses this to determine which path (port) to use for forwarding. The port
				with the lowest number has the highest priority.
	Cost	0-200000000		The switch uses this to determine which port is the forwarding port when the
				priority is equal. The path with the lowest cost to the root bridge is the active
				path. The estimated path cost is the industry standard for the port speed. The
				default path cost is the maximum speed for the port.
Commands
	Set Cist Bridge Priority:		Sets the Cist bridge priority.
	Set Cist Bridge Hello Time:		Sets the interval between two hello packets.
	Set Cist Bridge Maximum Age:		Sets the maximum age time.
	Set Cist bridge Forward Delay		Sets the forward delay.
	Set MSTP Max Hop Count		Sets the maximum hop count delay.
	Delay:

Rapid Spanning Tree

When a port running the standard STP is connected, it goes through the STP negotiation (listening -> learning -> forwarding or blocking) before it is available. If a client is trying to access a server through the switch running the STP negotiation, it cannot connect to it immediately. RSPT solves the lag time issue by setting the port directly to forwarding mode, which allows any server access request to be forwarded. RSPT is used on end node ports. For example, ports connected to PCs or servers, and not on uplink ports to other switches.
