NetComm NCT480 Hello Time, Forward Delay, Hold Time, Bridge Max Age, Valid values 6 ~ 40 Seconds

Item

Description

Hello Time	The value that all bridges use for HelloTime when this bridge is acting as the root.
Forward Delay	The value that all bridges use for Forward Delay when this bridge is acting as the root.
Hold Time	This time value determines the interval length during which no more than two
	Configuration bridge PDUs shall be transmitted by this node, in units of seconds.
Bridge Max Age	The maximum age time of Spanning Tree Protocol information learned from the
	network on any port before it is discarded, in units of seconds.
	Valid values: 6 ~ 40 (Seconds)
Bridge Hello Time	The amount of time between the transmission of Configuration BPDU (Bridge Protocol
	Data Units) by this node on any port when it is the root of the spanning tree or trying to
	become so, in units of second.
	Valid values: 1 ~ 30 (Seconds)
Bridge Forward Delay	This value, measured in units of seconds, controls how fast a port changes its spanning
	state when moving towards the Forwarding state. The value determines how long the
	port stays in each of the Listening and Learning states, which precede the Forwarding
	state. This value is also used, when a topology change has been detected and is
	underway, to age all dynamic entries in the Forwarding Database.
	Valid values: 4 ~ 30 (Seconds)
	Press the ‘Apply’ button to confirm the setting.
