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)
